  Tags: nitrogen potassium mineral fertilizers movable forms soy-beans. phosphor leached chernozem
  Description

  Data on influence of macro fertilizers on dynamics of content of more deficit elements of mineral nutrition in leached chernozem on sowings of soy-beans in conditions of perennial stationary experience of the chair of agrochemisrty are casted in the article. Content of ammonium nitrogen in soil depends in great extent on nitric and phosphoric fertilizers. Content of nitric nitrogen is higher than ammonium one. High coefficients of correlation (R=0,822 0,912) speak about authentic effectiveness of applied fertilizers in the rate N60P120K20 ; N60P120 K60. Content of movable phosphates in soil under application of duplex and triplicate rates of phosphor fertilizers separately and in combination with nitric and potassic fertilizers is increased. Potassic fertilizers determine soil enrichment with metabolic potassium among three applied macro fertilizers.
