Agrochemical characteristics of soils of natural fodder crop lands and effective application of chemicals allowing an increase in productivity of meadows and pastures.

摘要

Information is presented on grouping of soils for the degree of acidity and approximate doses of lime application in different soils of fodder crop lands in Russia. Data are tabulated on soil grading for the mobile phosphorus and exchangeable potassium contents. Data are tabulated on grouping of soils of natural meadows and pastures of the forest zone for the mobile phosphorus and exchangeable potassium contents, and for mobile forms content of trace elements. Information is included on optimal parameters of mobile phosphorus and trace elements content. Data are tabulated on fertilizer doses used on non-irrigated meadows and pastures in the forest zone, and doses and methods of trace element application in fodder crops (legumes and Poaceae for hay and green fodder). It is concluded that use of micro fertilizers on soils with low and medium mobile elements content allows achieving a balanced plant nutrition, and a significant increase in yield and quality of fodders.
