Were isolated and obtained. 2473, Enterobacter aerogenes 3271, Agrobacterium radiobacter 5006, Enterobacter nimipressuralis 5213, Bacillus sp. 6503, which are capable of transforming the poorly soluble organic and mineral compounds of soil phosphorus into easily absorbed plants, and the model of transformation of soil phosphorus inaccessible to plants into the available and nature of the inoculum bacterial activity on the surface of the seeds and in the corn root zone is carried out. The mechanism of conversion of phosphate-mobilizing bacteria to phosphorus compounds inaccessible to plants is accessible due to the ability of bacteria to produce carboxylic acids, in particular acetate and oily, and levans exopolysaccharides. The mechanism of action of active strains of phosphate-mobilizing bacteria on the corn production process is the products of metabolism of microorganisms - phytohormonal substances and enzymes. The preservation of a sufficient number of bacterial cells is shown P. polymyxa KV, A. radiobacter 599, A. radiobacter 1333, Bacillus sp. 2473, E. aerogenes 3271, A. radiobacter 5006, E. nimipressuralis 5213 (up to 100 thousand seeds / seed) on corn seeds for up to two months and bacteria Bacillus sp. 2473 and Bacillus sp. 6503 for a term up to three months (over 200 thousand seeds / seed) and application in the root zone of corn plants. The application of phosphate-mobilizing bacteria by applying them to seeds contributes to the increase in the number of bacteria that transform phosphorus compounds and increase phosphatase activity in the root zone of maize plants, which is a significant factor in improving the microbiological state of the soil when cultivating this crop. In the root zone of maize plants, the phosphate motility bacteria increased the degree of mobility of phosphates. Product Description popup.authors popup.nrat_date 2020-04-02 Close
