| description | The article presents the results of studies on the influence of mineral, biomodified mineral fertilizers and BisolbiFit biologics on the balance of basic nutrients in soil under fallow crops. According to the results of correlation and regression analysis, the total removal (grain plus straw) of basic nutrients strongly depended on the level of grain yield. The increase in grain yield from 2.85 to 3.45 t/ha was accompanied by an increase in the total removal of nitrogen from 73.6 to 130.1 kg/ha, phosphorus – from 30.8 to 68.4 kg/ha, and potassium – from 41.6 to 74.0 kg/ha. The balance of basic nutrients depended not only on the grain yield, but also on the doses of fertilizers applied. For all variants of the experiment, the nitrogen balance was consistently reduced from –55.4 to –22.1 kg/ha as the yield increased from 2.85 to 3.45 t/ha. The phosphorus balance decreased from –52.4 to –30.8 kg/ha, and its negative balance increased from background 1 (zero) to background 3 (½ NH4NO3m). The balance of potassium, as well as the balance of nitrogen and phosphorus, was negative for all variants of the experiment, and decreased from –60.9 to –40.0 kg/ha. |
