Achieving the balance of macronutrients with the No-till technology in the cultivation of agricultural crops with microbiological fertilizers

Abstract

The current research provides data on the change in the agrochemical parameters of soils with the No-till technology. The results, obtained from the agrochemical examination of the farm’s soils, show that the No-till technology reduces the degradation processes in the soils. In the soils of land plots where the No-till technology is applied, the nutrients are differentiated according to the conditions, while an increase in the content of macronutrients in the upper fifteen-centimeter soil layer is observed. In terms of the content of microelements, no clear differentiation in soil depth was found over a ten-year period. An analysis of the data obtained on the application of microbiological fertilizers on the content of nutrients in plants during the period of their maximum accumulation suggests that there is a slight increase in the nitrogen content in plants. The greatest effect on this indicator was revealed with the combined application of the following fertilizers: Azotovit, Fosfotovit (an increase of 0.51%), and BioAzFK (an increase of 0.22%). The yields of spring wheat with the application of microbiological fertilizers increased by 12.0-45.0%. Under the conditions of the pesticidal seed treatment with the fertilizers containing tebuconazole, fluxapiroxade, and thiamethoxam, the yields increased by 19.0-38.0%.
