REMOVAL OF POTASH BY A CROP OF CULTURES СROP ROTATION DEPENDING ON ACIDIC SOD-PODZOLIC LIGHT LOAMY SOIL, LEVEL OF SECURITY MOBILE POTASH AND DOZES POTASH OF FERTILIZER

Abstract

In clause the data of researches for 2006-2009 are submitted., in which the changes removal potash by a grain yield spring triticale, grain of peas, spring rape seeds, green weight pea-oat mixture are analysed depending on acidic light loamy soil, level of its security mobile potash and dozes potash of fertilizer. Is established, that on removal potash by basic production of the specified cultures the paramount influence is rendered by their biological features and level of productivity. The growth of a level of security of soil mobile potash with 200-250 up to 300-350 мг/kg increases removal of an element on variants with fertilizers on 0,3-38,1 of % depending on a kind of cultures. At the expense of decrease acidic of soil on control variants with среднекислой up to close to neutral, removal potash with the basic crop of researched cultures grows by 10,1-36,0%.
