EFFECT OF FERTILIZERS IN THE GRAIN-ROW CROP ROTATION ON SOD-PODZOLIC LIGHT LOAMY SOIL WITH VERY HIGH PHOSPHORUS MAINTENANCE AND POTASSIUM UNDER VARIOUS WEATHER CONDITIONS
Abstract
On sod-podzolic light loamy soil with very high phosphorus maintenance and potassium the high cost efficiency of introduction in a crop rotation of N330-630 is established. The greatest efficiency and delay of degradation of fertility is reached at application of N630P90K195 against the background of 50 t/hectare of manure. The efficiency of use of phosphoric and potash fertilizers in low doses (P15-20K30-60) is established that promotes increase in stability of efficiency in years with adverse weather conditions.
