Title	The World Financial Crisis and The Polish Economy
Słowa kluczowe	financial crisis, effects of financial crisis, anti-crisis action, Poland
Key words	financial crisis, effects of financial crisis, anti-crisis action, Poland
Abstrakt	The subject of the work is to provide an overview of the global financial crisis in the years 2007-2011; its course, symptoms and effects in the world and in Poland. The work presents the causes and the sources of crisis as well as corrective measures taken by governments and financial institutions. The subject literature and information from different national and international financial institutions and organisations were used as a source of research materials and data for analysis. The financial crisis appeared in Poland with some delay and was less intensive than in other developed countries. Anti-crisis measures taken in Poland complied with the recommendations of the European Union and the International Monetary Fund. The measures taken by the Polish central bank concerned the institutional sphere, the manner in which the financial policy worked and how it was pursued, as well as the real sphere of the economy, including especially enterprises, households and public institutions.

Tytuł	THE ROLE OF PRO-INVESTMENT MECHANISMS OF THE COMMON AGRICULTURAL POLICY IN ASSET REPRODUCTION OF FARMS IN CENTRAL AND EASTERN EUROPE
Title
Słowa kluczowe	common agricultural policy, central and eastern europe, pro-investment mechanisms
Key words
Abstrakt	The aim of this paper is to identify the role and importance of pro-investment mechanisms within the CommonAgricultural Policy in the reproduction of farm assets in countries of Central and Eastern Europe. Theexperimental material comprised unpublished microdata of farms originating from the FADN database of theEuropean Commission (data source: EU-FADN – DG AGRI). The time frame covered the years 2004–2015.Among all the farms selected for analyses only those ensuring data continuity throughout the entire investigatedperiod were used in the study. In each of the studied countries farms were divided into two groups: thegroup of beneficiaries of CAP pro-investment funds and the control group. For each farm the value of fixedassets was determined (excluding the value of land) and next the mean value for each group was calculatedin an individual country. The study showed that in most investigated countries both farms being and thosenot being beneficiaries of CAP pro-investment mechanisms are capable of reproducing their fixed assets;nevertheless, it is the farms receiving financial support for their investments that show a capacity to increasethe value of their fixed assets.

Tytuł	Classification of border subregions of Eastern Poland according to theIR level of socio-economic development
Title	Klasyfikacja podregionów przygranicznych Polski Wschodniej według poziomu rozwoju społeczno-gospodarczego
Słowa kluczowe	socio-economic development, demographic factors, infrastructure, spatial peripherality, economic peripherality, NUTS 3, Hellwig's measure of development
Key words	peryferyjność przestrzenna, peryferyjność gospodarcza, NUTS 3, miara rozwoju Hellwiga
Abstrakt	The paper presents the classification of subregions (NUTS 3) with permanent border crossings, in terms of the level of socio-economic development in 2008-2018. The study covered 9 subregions located in the following provinces: Warminsko-Mazurskie, Podlaskie, Lubelskie and Podkarpackie. Application of Hellwig's measure of development made it possible to group subregions according to three categories of the level of development: high, medium and low. The relatively high level of development characterized two metropolitan subregions: Olsztyński and Białostocki. Łomżyński subregion proved to be the weakest, but it was not completely devoid of any development potential. In comparison with the average values in the designated higher development classes, Łomżyński subregion was characterized by: positive natural increase, low values of indices describing ageing of local society and proportion of investment expenditure of local self-government units at a level similar to the leaders of the ranking. However, there is a concern that the relatively low level of spending of the EU funds and the persistent trend of population migration outflow, due to global trends of population ageing and depopulation of rural areas, may negatively affect the socio-economic situation of the subregion in the future.
Abstract	W artykule przeprowadzono klasyfikację podregionów (NUTS 3), na obszarze których znajdowały się stałe przejścia graniczne, pod względem poziomu rozwoju społeczno-gospodarczego. Badaniem objęto 9 podregionów usytuowanych w województwach: warmińsko-mazurskim, podlaskim, lubelskim oraz podkarpackim. Zastosowanie taksonomicznej miary rozwoju Hellwiga umożliwiło pogrupowanie podregionów wg trzech kategorii poziomu rozwoju: wysokiego, średniego oraz niskiego. Relatywnie wysoki poziom rozwoju charakteryzował dwa podregiony metropolitarne: białostocki i olsztyński. Najsłabszym okazał się podregion przemyski, jednak nie był on obszarem pozbawionym zupełnie potencjału rozwojowego. W porównaniu z przeciętnymi wartościami w wyznaczonych wyższych klasach rozwoju, podregion przemyski charakteryzowały: najniższy udział dróg gminnych i powiatowych o nawierzchni gruntowej i największa liczba stałych przejść granicznych. Mimo, że w badanym okresie w podregionie ubywało ludności, przyrost naturalny był dodatni. Ponadto, na terenie podregionu przemyskiego zarejestrowanych było najwięcej (w przeliczeniu na 10 tys. mieszkańców) fundacji, stowarzyszeń i organizacji społecznych, co świadczy o aktywności społecznej. Natomiast znacząca aktywność samorządów lokalnych przejawiała się w relatywnie wysokim przeciętnym wydatkowaniu środków z funduszy unijnych, co w przyszłości może skutkować poprawą sytuacji społeczno-gospodarczej, m.in. w zakresie infrastruktury, rynku pracy i demografii.

Title	Agribusiness Sector in Poland and Ukraine
Słowa kluczowe	agrobiznes, handel zagraniczny, wydajność pracy, struktura agrobiznesu, Ukraina
Key words	agribusiness, foreign trade, labor productivity, agribusiness structure, Ukraine
Abstrakt	W artykule podjęto próbę oceny porównawczej znaczenia agrobiznesu w gospodarce na Ukrainie i w Polsce. Analizą objęto lata 2001-2015. Dane pochodziły z oficjalnych źródeł statystycznych. Stwierdzono, że znaczenie agrobiznesu w Polsce w całym okresie zmniejszało się, a jego udział w wartości dodanej brutto w gospodarce wynosił w 2015 roku 6%, podczas, gdy na Ukrainie było to aż 15% i w ostatnich latach wzrastało. Agrobiznes miał też wysoki udział w eksporcie. W Polsce było to 15%, a na Ukrainie aż 38% w 2015 roku. W strukturze zatrudnienia w agrobiznesie dominowało rolnictwo z udziałem około 80% w obu krajach. Wewnętrzna struktura agrobiznesu była nowocześniejsza w Polsce, gdzie aż 58% wartości dodanej brutto było generowane w sektorze przetwórstwa żywności. Na Ukrainie było to tylko 24%. Znaczenie agrobiznesu w gospodarce ukraińskiej było wyższe niż w polskiej, ma on też tam bardziej surowcowy charakter. Na Ukrainie większy jest potencjał dalszego rozwoju wynikający z dużych zasobów ziemi rolniczej i możliwości wzrostu przetwórstwa żywności i jej eksportu.
Abstract	The article attempts to compare the importance of agribusiness in the economy in Ukraine and Poland. The analysis covered the years 2001-2015. The data came from official statistical sources. It was found that the importance of agribusiness to the Polish economy decreased over the entire period considered, its share in GVA in whole economy in 2015 was 6%, while in Ukraine it was as much as 15% and in recent years has been increasing. Agrobusiness also had a high share in exports. In Poland, it was 15, and in Ukraine as much as 38% in 2015. The employment structure in agribusiness was dominated by employment in agriculture with a share of about 80% in both countries. The internal structure of agribusiness was more modern in Poland, where as much as 58% of gross value added of agribusiness was generated in the food processing sector. In Ukraine, it was only 24%. The importance of agribusiness in the Ukrainian economy was higher than in Poland, it also has there a more raw character. The bigger potential for further development of agribusiness is in Ukraine, due to the large agricultural land resources and the large potential for increased production and processing of food and its exports.

Tytuł	Zmiany w produkcji i eksporcie malin i wiśni w krajach Europy Południowej i Wschodniej i ich znaczenie dla produkcji w Polsce
Title	Changes in Raspberry and Sour Cherry Production and Export in Southern and Eastern Europe and Implications for Polish Production
Słowa kluczowe	produkcja malin, eksport malin, produkcja wiśni, eksport wiśni
Key words	raspberry production, raspberry export, sour cherry production, sour cherry export
Abstrakt	Celem pracy było zbadanie jak zmieniała się produkcja i eksport owoców, które są domeną polskiej produkcji na rynku międzynarodowym, czyli malin i wiśni, w krajach Europy Wschodniej i Południowej w okresie 2006-2017. Do analizy produkcji owoców wykorzystano dane pochodzące z bazy Faostat, a wielkości eksportu – dane z bazy Comtrade. Przeprowadzona analiza wskazała na rozwój produkcji oraz wzrost eksportu malin w krajach o mniejszym areale upraw tych owoców oraz stabilizację w krajach posiadających dużą powierzchnię upraw malin. W przypadku wiśni, w większości krajów, zarówno o dużej jak i małej powierzchni nasadzeń, potencjał produkcyjny oraz zbiory owoców tego gatunku zmniejszały się. Eksport wiśni zwiększał się szczególnie z krajów o mniejszym potencjale w produkcji wiśni. Rozwój produkcji i eksportu malin z krajów o dotychczas mniejszym potencjale produkcyjnym może w przyszłości stanowić konkurencję dla Polski na rynkach międzynarodowych.
Abstract	The aim of the study was to examine the changes in production and export of raspberries and sour cherries, which are the domain of Polish production on the international markets, in the countries of Eastern and Southern Europe during the 2006-2017. There was used data from Faostat database for the analysis of fruit production, and from Comtrade database for the analysis of export volume. Study points to the development of production and an increase in the export of raspberries in countries with a smaller area of cultivation of this fruit crops and stability in countries with a large area of crops of raspberries. In the case of sour cherries, in most countries, both large and small area plantings, production potential, and volume of production of fruit of this species declined. The export of sour cherries increased particularly from countries with less potential in the production of sour cherries. The development of the production and export of raspberries from countries with lower production capacity may in the future be competition for Poland on the international markets.

Title	Changes on the Pork Meat Market in Poland in the years 2001 2017
Słowa kluczowe	pogłowie trzody, produkcja wieprzowiny, eksport, import, ceny
Key words	pig population, pork production, exports, imports, price
Abstrakt	Przedstawiono zmiany w podaży wieprzowiny w Polsce w latach 2001-2017. Pogłowie trzody chlewnej charakteryzowało się tendencją spadkową we wszystkich grupach zwierząt. W latach 2001-2007 import żywca wzrastał rocznie o 71 tys. szt., a w latach 2008-2017 o 603,5 tys. szt. Rosnąca skala importu żywca powodowała spowolnienie spadku produkcji mięsa. Eksport żywca charakteryzował się dużą zmiennością i był niewielki. Import mięsa charakteryzował się rosnącą skalą i tempem (prawie 32% rocznie w latach 2001-2008 i 3,1% w latach 2009-2017). Eksport mięsa rósł, a dynamika wzrostu od 2009 r. przewyższała skalę wzrostu importu, co zmniejszyło ujemne saldo handlu mięsem. Eksport przetworów z wieprzowiny charakteryzował się szybką tendencją wzrostową, a import niewielką. Ceny wieprzowiny w Polsce "podążały" za średnimi cenami w krajach UE. W średnim okresie tempo wzrostu cen w UE i w Polsce będzie niewielkie (0,8% rocznie), a Polska pozostanie nadal znacznym importerem żywych świń.
Abstract	Changes in pork supply in Poland in the years 2001-2017 were presented. The pig population was characterized by a downward trend in all groups of animals. In the years 2001-2007, livestock imports grew annually by 71 thousand pcs, and in the years 2008-2017 by 603.5 thousand pcs. The increasing scale of livestock import slowed the decline in meat production. Livestock export was characterized by high variability and was small. Meat imports were characterized by a growing scale and pace (almost 32% per annum in 2001-2008 and 3.1% in 2009-2017). Meat exports grew, and the growth rate since 2009 exceeded the scale of import growth, which improved the negative balance of meat trade. Exports of pork products were characterized by a rapid upward trend, and small imports. Pork prices in Poland "followed" average prices in EU countries. In the medium term, the growth rate of prices in the EU and in Poland will be small (0.8% per year). In the medium term Poland will remain a significant livestock importer.

Title	Marketing Margins and Added Value in the Food Supply Chain in Poland
Słowa kluczowe	marża marketingowa, wartość dodana, łańcuch dostaw żywności
Key words	marketing margin, added value, food supply chain
Abstrakt	Zagadnienie udziału producenta rolnego w finalnej cenie żywności budzi zainteresowanie naukowców oraz polityków. Komisja Europejska (2014, 2016) podjęła działania mające na celu wzmocnienie sektora rolnego w ramach łańcucha dostaw żywności. W Polsce zintensyfikowano promocję sprzedaży bezpośredniej. Działanie te mają na celu skrócenie łańcucha dostaw żywności oraz poprawę siły rynkowej producentów rolnych. Siła rynkowa oznacza zdolność przedsiębiorstwa do podniesienia ceny własnego produktu bez obniżenia poziomu sprzedaży na rzecz konkurentów. Celem badań było wskazanie tendencji w zakresie kształtowania się marż marketingowych oraz wartości dodanych w łańcuchu dostaw żywności. Pomiar ten służył poszukiwaniu odpowiedzi – które grupy produktów cechuje najwyższy poziom wartości dodanej i największa zdolność poprawy dochodów producentów rolnych? Szacowanie wartości dodanej obrazuje - gdzie trafia „złotówka żywnościowa” finalnego konsumenta?
Abstract	The issue of agricultural producer participation in the final food price is of interest to scientists and politicians. The European Commission (2014, 2016) commissioned the preparation of expertise in this area, as a result of which actions were taken to strengthen the agricultural sector. In Poland, for example, the promotion of direct sales has been intensified. These activities are aimed at shortening the food supply chain and improving the market power of agricultural producers. Market power means the ability of an enterprise to increase the price of its own product without reducing the level of sales to competitors. The aim of the research was to indicate trends in the area of marketing margins and added value in the food supply chain. This measurement served the search for the answer - which product groups have the highest level of added value and the greatest ability to improve the income of agricultural producers? The estimation of the value added illustrates - where does the "food zloty" of the final consumer go?

Słowa kluczowe	gospodarstwa specjalizujące się w uprawach polowych, wielkość ekonomiczna, efektywność, zadłużenie gospodarstw
Key words	field farms, economic size, efficiency, farm debt
Abstrakt	Celem badań była ocena wyników ekonomicznych i efektywności produkcji w gospodarstwach specjalizujących się w uprawach polowych sklasyfikowanych według wielkości ekonomicznej w pięciu krajach UE, tj. w Polsce, Bułgarii i Rumunii oraz na Litwie i Węgrzech. W badaniach wykorzystano średnie dwuletnie dane FADN EU, tzn. z lat 2015-2016. Zbadano dochodowość ziemi, efektywność produkcji oraz zadłużenie gospodarstw. Średnio w próbie najwyższy dochód bez dopłat na 1 ha UR uzyskano w gospodarstwach rumuńskich, natomiast w bułgarskich odnotowano stratę. W gospodarstwach bułgarskich z klas wielkości ekonomicznej 3-6 i litewskich z klas 1-3 koszty przewyższały wartość produkcji. Podobna sytuacja wystąpiła w gospodarstwach węgierskich i polskich z szóstej klasy wielkości ekonomicznej. Oznacza to, że produkcja była ekonomicznie nieefektywna. Zadłużenie gospodarstw zwiększało się wraz ze wzrostem wielkości ekonomicznej, jednak nie przekroczyło granicznej wartości, za którą przyjmuje się 50%.
Abstract	The aim of the research was to assess economic results and production efficiency in farms specializing in field crops classified by economic size in five EU countries: Poland, Bulgaria, Romania, Lithuania and Hungary. The analysis utilized the average two-year FADN EU data, from 2015-2016. The profitability of land, production efficiency, and farm debt were tested. On average, in the sample, the highest income without subsidies per 1 ha of UAA was obtained on Romanian farms, while on Bulgarian farms a loss was recorded. In Bulgarian farms from economic size classes 3-6 and Lithuanian from classes 1-3, the costs exceeded the value of production. A similar situation occurred in Hungarian and Polish farms from the sixth class of economic size. This means that production was economically ineffective. The debt of farms increased with the increase of economic size, but it did not exceed the limit value for which 50% is assumed.

Title	The Wood Pellet Sector: Barriers to Growth and Opinions of Manufacturers in Poland
Słowa kluczowe	renewable energy, wood pellet stoves, raw material, imports, quality, rural household
Key words	renewable energy, wood pellet stoves, raw material, imports, quality, rural household
Abstrakt	Biomass is a major source of renewable energy in the EU and Poland, stimulating the growth of the wood pellet sector. Wood pellet demand is stimulated by a complex interaction of market forces and policies including EU climate, energy, and environmental regulations, Poland’s program to improve air quality, and subsidies for the replacement of inefficient stoves used by households. This article focuses on the growth of the wood pellet industry, imports and exports in Poland, and wood pellet quality and use by households. The main issues faced by the EU wood pellet sector between 2013 and 2016 are further considered in the context of opinions of Polish wood pellet manufacturers. Industry opinions were collected in response to an open-ended question that probed for the main issues faced by wood pellet producers during the survey implemented by the authors in 2019. Respondents identified difficulties in obtaining raw material for pellet production and poor pellet quality as major problems. Although the majority did not feel concerned about competition from imported wood pellets, a small number of respondents viewed such competition as a problem reflecting the reversal of decreasing imports in 2017. Overall, the domestic wood pellet industry can be expected to grow because of increasing pressure to expand the use of renewable energy and will be driven by the household sector switching to more efficient, wood burning stoves. Additionally, the expanding area of private Polish forests may become a source of much-needed raw material for wood pellet manufacturing.

Title	The Impact of Innovation on the Global Competitiveness of Polish Meat and Dairy Enterprises
Słowa kluczowe	innovation, competitiveness, meat, dairy, enterprise, global market, Poland
Key words	innovation, competitiveness, meat, dairy, enterprise, global market, Poland
Abstrakt	The aim of the study was to analyse innovations implemented in the milk and meat industries, and their impact on increasing competitiveness. The study showed that the 2010-12 period saw the most product and process innovations being introduced. On the other hand, innovations in marketing were found to be more popular in 2013. Three groups of similar innovations were distinguished. The milk industry stood out when it comes to the extent of innovations implemented. Fewer innovations were found in the poultry meat industry. Beef and pork meat processing was the least innovative. The innovativeness of enterprises is greater with larger numbers of employees and the increase in scope of their field of operation. The implementation of innovations resulted in: improvement of the quality of goods (services), increase in stock, productive capabilities and revenues from sales, emergence of new markets, increase in competitiveness and prestige of the firm. Those are confirmed by the very good performance of foreign trade and better competitiveness rates of Polish meat producers.

Słowa kluczowe	Wspólna Polityka Rolna, płatności bezpośrednie, płatność redystrybucyjna, Polska
Key words	Common Agricultural Policy, direct payments, redistributive payment, Poland
Abstrakt	W niniejszym opracowaniu, w ramach badań diagnostycznych, dokonano pomiaru aktualnego stopnia koncentracji pomocy dystrybuowanej w ramach systemu wsparcia bezpośredniego dla rolników w Polsce oraz przedstawiono jego zróżnicowanie regionalne. Z kolei w ramach badań symulacyjnych dokonano kwantyfikacji skutków redystrybucyjnych stosowania – w różnych wariantach – instrumentu wyrównującego przyznawane kwoty wsparcia między gospodarstwami. Może to stanowić podstawę oceny ex ante alternatywnych opcji wdrożeniowych płatności redystrybucyjnej. Badania doprowadziły m.in. do wyznaczenia przedziałów obszarowych gospodarstw korzystających na stosowaniu płatności redystrybucyjnej – w obecnym kształcie oraz w przykładowych wariantach alternatywnych. W części końcowej artykułu sformułowano kilka rekomendacji w zakresie projektowania płatności redystrybucyjnej na poziomie krajowym w zależności od celów, które mają być osiągane za pomocą tego instrumentu.
Abstract	The article describes a diagnostic study measuring the degree of concentration of the aid which is currently distributed under the direct support system for farmers in Poland; it also presents the regional differentiation in aid concentration. The author conducted a simulation test quantifying the redistributive effects of applying various variants of an instrument equalising the amounts of support granted to farms. This can make the basis for an ex-ante assessment of alternative options of the implementation of redistributive payment. The research enabled the identification of ranges of the areas of farms which benefit from the current shape of redistributive payment and which may benefit from alternative variants given as examples. The final part of the article contains several recommendations on how to design redistributive payment at a national level, depending on the goals to be achieved with this instrument.

Słowa kluczowe	handel międzynarodowy, przemysł spożywczy, handel wartością dodaną, globalne łańcuchy wartości, GVC
Key words	international trade, food industry, value-added trade, global value chains, GVC
Abstrakt	Celem artykułu jest wskazanie różnic w liczeniu udziału poszczególnych gałęzi produkcyjnych w eksporcie, w zależności od danych przyjętych do obliczeń, na przykładzie produktów spożywczych, napojów i tytoniu. Dane te mogą być statystykami przedstawiającymi eksport mierzony brutto jak i w ujęciu wartości dodanej. W związku z rozwojem powiązań gospodarczych między krajami i uczestnictwem w globalnych łańcuchach wartości, statystyki prezentujące eksport krajowej wartości dodanej precyzyjniej obrazują znaczenie poszczególnych gałęzi dla gospodarek badanych krajów. Porównania udziałów w eksporcie w ujęciu tradycyjnym i wartości dodanej pozwalają wskazać gałęzie, których znaczenie jest przeszacowywane lub nieoszacowywane w statystykach brutto.
Abstract	The aim of the article is to indicate differences in counting the share of exports for individual branches of production, based on the data used for the calculation, on the example of food, beverages and tobacco. Statistics can measure exports in two ways: gross export and in terms of value added. In connection with the development of economic ties between countries and participation in global value chains, statistics presenting exports of domestic value added illustrate more precisely the importance of particular industries for the economies of different countries. Comparisons of export shares in traditional and value-added terms helps to show those branches whose importance is overestimated or underestimated in gross statistics.

Title	Rural Demographic Problem Areas in Poland
Słowa kluczowe	rural areas, demographic problems, Poland
Key words	rural areas, demographic problems, Poland
Abstrakt	Demographic problem areas are perceived as one of the most important types of problem areas and require special research interest. Problem areas conditioned by population factor most often refer to rural areas. Presented article aims to identify and delimit rural demographic problem areas in Poland. The study covered rural areas distinguished on the basis of the classification of the European Commission DEGURBA The analysis enabled to identify depopulation areas, areas with disrupted population reproduction (ie areas of permanent natural decline), areas of permanent outflow of population, areas with impaired population structure by age and areas with disrupted population structure by sex in the group of people of marriage age (20-34 years). To indicate clusters of communes characterised by the presence of the unfavourable demographic phenomena and processes (rural demographic problem areas) the measure of local spatial autocorrelation (Anselin Local Moran's I) was applied. The application value resulting from the research may be the improvement of the effectiveness of public intervention carried out as part of the development policy.

Title	Environmental Assessment of the Life Cycle of Bovine Compound Feeds from a Feed Milling Plant in a Large Commercial Farm in Wielkopolska Region, Poland
Słowa kluczowe	environment, life cycle analysis, impact category indicator, compound feed, feed mill, Poland
Key words	environment, life cycle analysis, impact category indicator, compound feed, feed mill, Poland
Abstrakt	In recent years, the importance of environmental threats associated with intensive livestock production has been emphasized. Compound feeds make up a part of the animal production chain. A complete assessment of the animal production system with regard to environmental criteria is therefore impossible without considering the environmental consequences of feed production. The goal of this research is to fill the gap in an environmental assessment of production processes of compound feeds in Poland. The study presents an assessment of production impacts of bovine compound feeds according to Life Cycle Analysis (LCA) methodology. The data for analysis were based on the set of information obtained from the feed milling plant located in a commercial agricultural enterprise in the Wielkopolska region in the years 2015-2016. An inventory table of inputs was prepared in relation to the functional unit of 1 ton of compound feeds and two phases of production processes, i.e. upstream and core. For average compound feed, the impact category indicators for the global warming potential, acidification, eutrophication, photochemical ozone formation, consumption of mineral resources, fossil fuel resources and the emission of the respirable particles were respectively: 605.9 kg CO2 eq, 8.73 kg SO2 eq, 3.32 kg PO4 eq, 0.73 kg ethylene eq, 3.4x10-3 kg antimony eq, 5141.1 MJ and 2.25 kg PM2.5 eq. The upstream phase had the greatest effect on investigated impacts, while the core processes phase had a relatively low impact on environmental threats. It is recommended to broaden the scope of the research for a larger group of feed milling plants with more complex manufacturing processes, with a more branched supply structure and a wide range of compound feeds for different animal types. The obtained data can be a valuable source base in prospective analyses of the life cycle of various animal products in Poland.

Title	The Impact of Climate Change on the Efficiency of Nitrogen Use and its Losses
Słowa kluczowe	zmiany klimatu, plony, efektywność, azot, straty
Key words	climate change, yield, NUE, nitrogen, losses
Abstrakt	Celem badań było określenie przewidywanych plonów, efektywności wykorzystania N (NUE), wymywania N, emisji N2O i NH3 w zależności od zmian klimatu do 2050 r. Badania wykonano, z zastosowaniem modelu DNDC, dla okresów lat 1991-2010, 2011-2030 i 2031-2050 oraz 10 lokalizacji w Polsce. W symulacjach uwzględniono zmianowanie roślin: kukurydza na ziarno – jęczmień jary – rzepak ozimy – pszenica ozima, które uprawiano na glebach lekkich, średnich i ciężkich, przy nawożeniu wynoszącym odpowiednio: 140, 90, 160 i 120 kg N ha-1. Stwierdzono, że zmiany klimatu przyczynić się mogą do wzrostów plonów kukurydzy na ziarno (6-43%) i rzepaku ozimego (2-8%), spadków plonów pszenicy ozimej (od -18 do -5%) oraz nieistotnych zmian w plonach jęczmienia jarego. NUE wzrośnie w uprawie kukurydzy (2-17%), zmaleje w uprawach pszenicy ozimej (3-22%) i jęczmienia jarego (3-17%) oraz nie ulegnie zmianie w przypadku rzepaku ozimego. Zmiany NUE oraz straty N nie wpływały na konieczność zmniejszenia dawek azotu w przyszłej uprawie badanych roślin.
Abstract	The aim of the study was to determine the expected yields, the efficiency of N (NUE) use, N leaching, N2O and NH3 emissions depending on climate change until 2050. The research was carried out using the DNDC model for the years 1991-2010, 2011-2030 and 2031-2050 as well as 10 locations in Poland. In the simulations, the crop rotation were considered: maize for grain - spring barley - winter rape - winter wheat, which was grown on light, medium and heavy soils, with fertilization of, respectively: 140, 90, 160 and 120 kg N ha-1. It was found that climate change can contribute to increase in the yield of maize (6-43%) and winter rape (2-8%), decreases in winter wheat yield (from -18 to -5%) and negligible changes in yields of spring barley. NUE will increase in the cultivation of maize (2-17%), it will decrease in winter wheat (3-22%) and spring barley (3-17%) crops and will not change in the case of winter oilseed rape. NUE changes and N losses did not affect the need to reduce nitrogen doses in the future cultivation of the studied plants.

Title	Verification of the Possibilities to Reduce Ammonia Emission for Various Slurry Application Practices in Poland
Słowa kluczowe	rolnictwo, gnojowica, amoniak, emisje, ograniczenie emisji
Key words	agriculture, slurry, ammonia, emission, emission reduction
Abstrakt	Rolnictwo polskie zobowiązane jest do redukcji emisji amoniaku (NH3), w stosunku do 2005 r., o 1% corocznie w latach 2020-29 oraz o 17% corocznie od 2030 r. Znaczącym źródłem emisji jest stosowanie gnojowicy. W Polsce aplikuje się ją głównie rozbryzgowo na powierzchnię pola i przyoruje po 4-24 godzinach od aplikacji. W pracy zastosowano model ALFAM2 do scharakteryzowania emisji NH3 z rozbryzgowego stosowania gnojowicy w zależności od specyficznych dla Polski: dawek gnojowicy, jej suchej masy, temperatury powietrza, prędkości wiatru, opadów oraz pH gnojowicy. W stosunku do emisji NH3 z gnojowicy stosowanej na powierzchnię pola oszacowano emisje powstające przy aplikacji gnojowicy za pomocą wężów wleczonych, wężów z redlicami oraz aplikacji do otwartych szczelin, płytko doglebowo i głęboko doglebowo. Na podstawie uzyskanych wyników oszacowano wielkości redukcji emisji dla podstawowych praktyk jej aplikacji.
Abstract	Polish agriculture is obliged to reduce ammonia (NH3) emissions, compared to 2005, by 1% annually in 2020-29 and by 17% annually from 2030. A significant source of emissions is the use of slurry. In Poland, it is mainly broadcast on the field surface and incorporated 4-24 hours after application. The ALFAM2 model was used to characterize the NH3 emissions from the slurry broadcast depending on the specific parameters for Poland: doses of slurry, its dry matter, air temperature, wind speed, precipitation and the pH of the slurry. In relation to the NH3 emission from the slurry applied broadcast to the field surface, the emissions resulting from the application of slurry by trailing hoses, trailing shoe, open slot injection, shallow and deep injection were estimated. On the basis of the obtained results, the emission reduction values were estimated for the basic practices of its application.
