| 5. The balance of phosphorus in the agriculture of Poland - Arkadiusz Tujaka, Henryk Terelak Abstract. Agriculture is a major factor interfering in the natural cycle of nutrients, particularly through the intensifi cation of production. Phosphorus compounds are regarded as the most hazardous threat generated by farming. The balances of phosphorus, as one of many agroenvironmental indicators, are very important source of information about rural infl uence on formation of environment conditions. They apply to all levels of agriculture, starting with a single cultivated fi eld, through the farm, up to the catchments, regions and whole countries. Regarding NUTS 0 level, Poland belongs to the group of countries with the lowest balance of phosphorus from among the other UE and OECD countries taken into comparison in the paper. The greater values of phosphorus balance were noticed in the countries with intensive agriculture i.e. in Germany and Denmark. The study of national and regional phosphorus balance (soil surface nutrient balance according to OECD) showed that the difference stems from the climatic and soil conditions as well as from phosphorus management practices. The differentiation of phosphorus balance on the greatest river catchments level in Poland was not found, whereas a larger diversity, concerning the range of phosphorus management propriety, was found at a province level (NUTS 2). key words: phosphorus balance, effi ciency use, OECD methodology |
