Microbial Solution of Growth-Promoting Bacteria Sprayed on Monoammonium Phosphate for Soybean and Corn Production

Common fertilizers present a low use efficiency caused by nutrient losses (e.g., through leaching, volatilization, adsorption, and precipitation in solution as well microbial reduction immobilization) that create significant limiting factor crop production. Inoculation with Plant Growth-Promoting Bacteria (PGPB) is presented an alternative to increasing fertilizer efficiency. The goal of the study was test hypothesis PGPB (solution Bacillus subtilis, amyloliquefaciens, licheniformis, pumilus) can be strategy increase monoammonium phosphate (MAP) efficiency, root growth, assimilation soybean corn cultivated arenosol oxisol. A greenhouse developed rates (rates: 0, 1, 1.33, 1.66–2.0 L per ton fertilizer) sprayed on MAP applied oxisol corn. Results showed both soils crops, there variation soil biological activity during experiment. On day 45, + promoted beta-glucosidase ammonium-oxidizing microorganism activities arenosol. increased growth crops. dry matter associated phosphorous content soil, indicating absorbed plants, consequently resulting higher accumulation plant. Based results, conclusion increases oxisol, direct effect rooting.
