INFLUENCE OF FERTILIZER SYSTEMS BALANCE OF NUTRIENTS ANDAGROCHEMICAL INDEXES OF SOD-PODZOLIC LOAMY SAND SOIL

Abstract

On sod-podzolic sand soil at high efficiency of crop rotation (473,9 centner of fodder unit) N433Р290К590 application against 60 t/hectare of manure was insufficient for preservation of humus content in soil at initial level, this rate of fertilizers has provided only a small gain of mobile forms of phosphorus and potassium. Due to tillage of straw the humus content in soil has increased on 0,04-0,07 %, mobile forms P2O5 - on 8-16 mg/kg, K2O - on 20-29 mg/kg.
