DEPENDENCE OF THE VOLUME OF NATURAL FERTILIZER CONSUMPTION IN RELATION TO THE LEVEL OF LIVESTOCK DENSITY IN POLAND

Abstract

The article presents the results of an analysis of the dependence of the volume ofconsumption of various types of natural fertilizers in Poland, on the intensity of animal husbandry. As a measure of the intensity of animal husbandry, the level of animal stocking rate was adopted. The scope of the analysis covered the years 2017-2020. The amount of natural fertilizer consumption was determined at the level of voivodeships. The study showed that the size of animal stocking rates in Poland is determined by the share of cattle, followed by pig and poultry stocking rates. Analysis of basic statistical indicators, confirmed spatial inequality with regard to the location of animal husbandry in Poland at the regional level. The intensity ofmanure application is a reflection of the level of livestock stocking, and this relationship isexplained by a 2 polynomial regression, where R2 = 0.7326. The highest intensity oflivestock and natural fertilization in Poland was the Podlaskie Voivodeship, where theaverage level of natural fertilizer use in recent years was 11.48 t/ha UAA, and the stocking rate was 85.2 LU/100 ha UAA, while the average level of use for Poland is 4.64 t/ha UAA. The amount of each type of manure applied per large animal unit (LU) is relatively constant, and in Poland in recent years has been: 6.0 t of manure, 0.8 t of poultry manure, 1.3 m3 of liquid manure and 2.4 m3 of slurry.
