Efficiency of Biofertilizers Azobacterin and Kaliplant for Grain Crops Growingon Eroded Sod-Podzolic Soils
Adaptation of plants is of importance under growing in stress conditions on eroded soils. Application of biofertilizers azobacterin and kaliplant lead to the improvement of plant adaptive potential as a result of direct stimulation effect (phytohormons, plant nutrition improvement) as well as indirect influence (biological control of phytopatogens). Additive impact of azobacterin and kaliplant on plant growth and nutrition provided crop yields and crop quality increase on eroded soddy-podzolic soils. As a rule the largest positive effect on crop yield was observed in stress conditions on moderately and severely eroded soils. Azobacterin application resulted in the increase of crude protein content in grain of spring barley and winter rye. Kaliplant application resulted in the increase of critical and indispensable amino acids contents in spring wheat protein.
