ABSTRACT
Use the resources and structure of the soil has been studied in Podkarpackie province in the years 1946-2005, divided into three periods of time due to administrative changes in the country and the region (I: 1946-1970, II: 1975-1995, III: 2000-2005). The three time periods studied decreased share of agricultural land and arable land in the general area of the province. In the years 2000-2005 has increased significantly the share of forests and other lands, at the expense of the exclusion of the arable lands and grasslands in agricultural production, which turned into fallow and uncultivated land. The farms 32.7% of arable lands was excluded from the cultivation and has evolved into a fallow and uncultivated land. The holdings of the public sector, this situation was even more unfavorable as it was, and took 86.1% of arable lands for fallow and outfield. During the study period, the structure of individual crops sown undergone substantial changes in the direction of simplification cereal monoculture. The soils of Podkarpackie province are acidic and urgently require liming treatment. Unfavorably was presented a richness soils of available forms macronutrients (P and K) in Podkarpackie province, especially in available phosphorus, which was the result of limitations of organic fertilization and low consumption of mineral fertilizers. Over 90% of agricultural soils of Podkarpackie province exhibits natural content of metals (Cd, Cu, Pb and Zn). The aim of the study was to analyze the structure of the Earth's land use and soils, taking into account the structure of crops and some elements of soil fertility and degradation in the context of a slowdown adverse changes.
