Reducing the dose of mineral fertilizers using organomineral bionutrients

Abstract

The results of work on the creation of a line of complex bionutrients mainly of organomineral synthesis and biological origin, based on physical methods of activation of known and long-used in agricultural practice products of metabolism of living organisms (animals- microorganisms- annelids), which, due to the activation of metabolic processes in plants, would enhance the immune status of plants and improve metabolic processes, thereby reducing the need for chemical pesticides and mineral fertilizers. The aim of the work was to study the effectiveness of the use of a bionutrient based on a combination of activated humates and organo-mineral compounds in a field experiment on winter wheat at various levels of mineral nutrition. It was found that the combined use of mineral fertilizers and bionutrients increased the yield of winter wheat by 22-23%. According to the impact on the yield of winter wheat, the use of bionutrients in the dry year of 2022 guaranteed and more effectively replaced the use of mineral fertilizers. With an increase in the dose of mineral fertilizers in winter wheat grain, the content of gluten and protein increased. A similar increase in the content of gluten and protein was noted in winter wheat grain treated with a bionutrient preparation. The combined use of NPK and bionutrient caused the highest content of gluten and protein in winter wheat grain. The use of the bionutrients contributed to an increase in ear productivity, improved overwintering and plant survival during the growing season, and increased plant resistance to Swedish fly infestation.
