Effects of Apatite Concentrate in Combination with Phosphate-Solubilizing Microorganisms on the Yield of Ryegrass Cultivar Izorskiy

Soil microorganisms play a vital role in increasing the availability of phosphorus (P) for plants through mineralization organic P and solubilization precipitated compounds. In this two-year study, we analyzed several P-solubilizing (PSMs) genus Bacillus their consortiums ability to release soluble from apatite concentrates various grinding degrees using ryegrass (Lolium multiflorum Lam.) as model plant. The effects were accessed by analyzing plant growth nutrient assimilation. greatest effect on root system development biomass accumulation (dry weight) was observed concentrate standard combination with megaterium BI14 subtilis BI2 velezensis BS89 strains. Although introduction led an increase content total strontium soil, levels did not exceed maximum allowable concentration, mobile unchanged; importantly, use tested PSMs decrease green ryegrass. Our results indicate that biologized represent promising fertilizers can provide source be readily assimilated plants.
