Description
Questions of microbial plant protection become more relevant. The use of microorganisms can solve the following problems: biologization of agriculture and sanitation of soil. Application of various physical factors affecting the microorganisms reduces their number. This influences the efficiency of their use. This article gives examples of the application of pressure in the biotechnological process of microbial preparations and their use in the process of spraying. The effect of pressure on nonspore bacteria - Azotobacter chroococcum, spore-forming bacteria - Bacillus megatherium and fungi - Trichoderma viride has been presented in this article. These microorganisms are used in the tank medium for protecting plants against diseases and pests developed by Ltd. "Kuban agrotehnoloogy" of Kuban State Agrarian University. Efficiency is the simultaneous application of tank medium of microorganisms with herbicide. It was found that the application of the tank medium of microorganisms for spraying is necessary to limit the pressure of 4.5 atm. Тhe use of higher spraying modes effects on reducing the number of viable bacteria. This fact has not been checked against fungi

Description
The article presents the results of a study of microbiological content of the soil after microbial protection of plants. Preparations were obtained by the technology developed by Ltd. "Kuban agrotehnoloogy". We have established the presence of bacteria Azotobacter chroococcum and fungus Trichoderma viride in the soil. Investigation of Trichoderma viride was made with using plant residues. It is proved that the use of microbiological preparations for plant protection have positive effect to improve the microbiological composition of soil. We have substantiated the example of the summary application of Azotobacter chroococcum and Trichoderma viride for plant protection. A number of provisions of the article have a scientific basis of view for the "food chain" microorgaisms. Trichoderma viride enzymatic hydrolysis products are good food source for Azotobacter chroococcum . Azotobacter chroococcum facilitates transfer of available nitrogen for plant nutrition. These microbiological preparatioты were recommended for seed treatment of plants during the growing season and crop residues after harvest. We used such culture media as Capek, Beijerinck and Ashby. Soil samples for research were selected by "Temizhbekskaya" Ltd in the Stavropol region. The study may be interested for agronomists, biotechnologists, mycologists, microbiologists
