Effect of the bacterial fertilizer Kaliplant on the yield and quality of spring wheat grown on eroded soils
Prospects and economic substantiation of the bacterial fertilizer Kaliplant (K-mobilizing bacteria) application for spring wheat growing are established in the field experiment conducted in accordance with the geomorphologic profile of Luvisol sandy loam soil on loess loam. Introduction of the bacterial fertilizer Kaliplant resulted in the increase of spring wheat productivity at all slope elements - by 7.0-9.1 c/ha f.u. The most significant positive effect is observed when spring wheat is grown on severely eroded soil, that indicates antistressful properties of the Kaliplant. The bacterial fertilizer has a good influence on biological value of spring wheat protein owing to the increase of critical and irreplaceable amino acids content including lysine. The most significant improvements of protein biological values are observed when spring wheat is grown on moderately eroded and not eroded soils.
