The last decades in biological science have been marked by amazing discoveries, a number of which indicate that symbiosis and association with microorganisms are the basis of plant life. The roots of plants are densely surrounded by bacteria and microscopic fungi, forming a comfortable environment for the life of the plant. At the same time, the composition of microbial communities of the root zone is not always acceptable for the harmonious growth and development of plants. This is due to unfavorable ecological conditions, excessive chemicalization of agriculture, etc. In this regard, the idea of artificial provision of agricultural crops with agronomically valuable microorganisms arose. This process can be optimized by the use of specific microbial preparations such as Ryzohumin, Polimiksobakteryn, Albobakteryn, Diazobakteryn, Biohran, Khetomik, Mikrohumin, which are also called microbiological fertilizers.
Microbiological preparations for plant growing are the cultures of microorganisms obtained by selecting among the most active nitrogen-fixing, phosphate-mobilizing, growth-stimulating bacteria and fungi, and propagated in nutrient medium by biotechnological methods. The number of microorganisms in the preparations is 1-10 billion in 1 g (milliliter), which makes it possible to ensure the dominance of the required bacteria or micromycete in the root zone of plants using a small amount of the preparation during the pre-sowing treatment of seeds of cultivated plants (50-300 g, depending on the plant species and seeding rate).
The use of biofertilizers contributes to the following.
1. Increase and acceleration of germination, health of seeds.
2. Improvement of the microbiological composition of the soil.
3. Increase of the level of resistance of plants to external influences.
4. Improvement of nitrogen and phosphorus nutrition of plants.
5. Increase of the mineral fertilizers use coefficients.
6. Increase of the crop yield.
7. Improvement of the quality of products.
8. Restoration of natural soil fertility.
These effects are explained, first of all, by the production of phytohormones (auxins, gibberellins, cytokinins) by microorganisms. This contributes to the formation of a powerful root system, which positively affects the absorption of nutrients. Phytohormones also, through changes in the activity of plant enzyme systems, contribute to the accumulation of sugars in the tillering nodes of winter crops, which affects their overwintering. Rhizosphere colonization by necessary microorganisms and constant supply of plants with phytohormones activates the process of photosynthesis. In addition, the activity of nitrogen fixation and phosphate mobilization increases. Formed plant-microbial associations and symbiosis can resist infection with pathogenic microorganisms for a long time.
The sum of these effects contributes to an increase of the yield of crops and the improvement of the quality of plant products.
Microbial preparations are effective when used in organic farming systems. At the same time they are one of the most powerful factors affecting the productivity of plants. Together with this, biopreparations influence the production process of agricultural crops when they are used in traditional agricultural technologies (using mineral fertilizers). In this case, due to the increase in the size of the root system and its absorptive capacity, the degree of absorption of the active substance from fertilizers increases substantially. Agrochemists and agricultural practicians know that nitrogen absorption from fertilizers does not exceed 35-50%, phosphorus absorption does not exceed 20%, and potassium absorption is within 25-60%, depending on the type of soil. Bacterized plants are able to absorb 20-30% more nutrients. This makes it possible to increase the effectiveness of fertilizers (if necessary, to abandon the corresponding part of fertilizers without reducing the yield of agricultural crops).
