CROP ROTATION PRODUCTIVITY AND FERTILITY OF LUVISOL LOAMY SAND SOIL UNDER DIFFERENT FERTILIZER SYSTEM
Abstract
Under the implementation of different fertilizer systems of agricultural cultures in rotation such as pea-oat mixture - winter rye sowing with clover - madow clover - winter triticale cultivated in sod-podzolic sandy loam soil the most effective-is the organo-mineral system of fertilization, involving the use of phosphorus and potassium fertilizers (R40K80) the rate of 100% compensation for removal of P2O5 and K2O and the introduction of 84 kg of nitrogen-fertilizers in three terms against the 8 t/ha of organic fertilizer, which provides a pro-inductance rotation of 95.9 kg/ha. However, the fertility of the soil at the same time has worsened: the acidity of the soil has increased by 0.33 units; the content of mobile phosphorus and potassium has decreased by 23 and 44 mg/kg soil respectively.
