ОРГАНИЧЕСКАЯ КОМПЛЕКСНАЯ ПОДКОРМКА С ФУНКЦИЕЙ ПОЧВОУЛУЧШИТЕЛЯ НА ОСНОВЕ ДИАТОМИТА ДЛЯ ОРГАНИЧЕСКОГО ЗЕМЛЕДЕЛИЯ

Abstract

The aim of the research is to develop a multi-component organic complex feed with the function of a soil enhancer based on nanostructured diatomite using organic waste and raw materials processing products and to study its impact on agrophytocenosis indicators and field crop yields. The work used the results of research on the development of multicomponent organic fertilizers, as well as their effectiveness on the pilot field of the Samara State University in 2017-20. (southern forest-steppe of the Volga region). It was revealed that the development of multicomponent organic fertilizers based on nanostructured diatomite and organic waste and raw materials processing products is an effective direction for the development and dissemination of organic farming technologies, especially in the conditions of increasing aridity of the growing season. Multicomponent fertilizer - an organic complex feed with the function of a soil enhancer based on diatomite - reduced the involvement of winter wheat plants with root rots by 12.7-29.7% compared to the control, and by 6.0-8.0% compared to mineral fertilizer. The yield of winter wheat in organic fertilizer was inferior to the productivity in mineral - by an average of 0.9-6.5%, with the cost of introduced mineral fertilizer of about 2000.00, and organic - 1710.00 rubles/ha. The greatest yield was achieved on the variant with mineral fertilizer on the background with biologics - 23.8% more control, but only 0.9% more than the variant with organic fertilizer. Therefore, multi-component polyfunctional organic fertilizer based on diatomite is not inferior in agronomic and economic efficiency to mineral fertilizer, which is a significant prerequisite for the spread of organic farming technologies.
