Microbiological processes in rhizosphere of plants of peas at application of fertilizers and rhizohumin

Abstract

The purpose. To investigate influence of application of fertilizers and microbic preparation rhizohumin upon microbiological processes in rhizosphere of plants of peas and productivity of culture. Methods. Field researches, microbiological and biochemical methods of researches. Results. Favorable for development of agronomically valuable microorganisms at cultivation of peas on leached chernozem and formation of productivity of culture is after-action of dung, and also dose of mineral fertilizers, which do not exceed N60P60K60. Use of rhizohumin is effective. Influence of biological product upon formation of productivity of peas in experiment is equivalent to action of fertilizers in the dose of N30P30K30. Conclusions. Technique of cultivation of peas should necessarily include pre-seeding bacterization. At cultivation of the culture on leached chernozem the optimum backgrounds as to ecological-and-economic parameters are after-action of dung, application of fertilizers in dose which do not exceed N60P60K60.
