Due to the increase in organic matter in the soil, water absorption capacity and
efficiency of moisture use by plants significantly increases. In the conditions of modern
resource provision of the agricultural sector, in particular the high cost of mineral
fertilizers, the missing volumes of organic application should be developed and modern
approaches to plant nutrition should be implemented. The most effective and cheapest
method is the use of biologics and growth regulating substances for presowing
treatment of seeds or planting plants in the main periods of the growing season. This
allows to reduce the dose of mineral fertilizers, increase crop yields, increase their
resistance to drought and adverse environmental conditions, has a positive effect on
the main indicators of quality of grown products, elements of fertility and significantly
improves the efficiency of the use of plants moisture on the formation of the crop unit.
With such resource-saving approaches it is possible to achieve a certain stability
in the management of agricultural crops, including in the zone of unstable moisture
when changing soil and climatic conditions of the southern Steppe of Ukraine, which
is the breadbasket, the source of vegetables, melons and other crops.
