The results of field studies of the use of biological products and microfertilizers in the cultivation of winter wheat in the production conditions of the Krasnodar Territory are presented. Indicators of a comparative assessment of economic and new schemes for the application of fertilizers and plant protection products from the point of view of agricultural and economic efficiency are given.

The influence of leaf fertilizing with the use of preparations of biological origin and fertilizers with trace elements in the cultivation of corn in conditions of unstable moisture has been studied. The economic efficiency indicators of various drug application schemes are given. As a result of the conducted research, it was found that the use of preparations of biological origin and fertilizers with trace elements led to an increase in yield by 2.1 - 4.6 c / ha and affected the growth of profit by 2.9 - 7.5 thousand rubles/ha.

The article presents the data of industrial experience of using biological preparations in the technology of cultivation of winter wheat in the zone of unstable moistening of the Krasnodar Territory. Based on the results of the studies, it was found that the use of the complex biological product Albit and the concentrated humic fertilizer Lignogumat improves the biometric parameters of plants (elongation of the ear by 5.6%, an increase in the number of grains per ear by 17.9% and the weight of 1000 grains by 5.9%), there was an increase in yield by 3.0 c/ha (or 5.1%) and an increase in profit by 4027 rubles/ha.
