Abstract

The main objective of the study is to develop an environmentally friendly technology and organize the production of biological products, as well as to conduct laboratory and field tests to determine the effectiveness of the effect of chelate complex biological products based on potassium humate, enriched with NPK and Mo. A description of the technology for obtaining potassium humate is shown, as well as physical and chemical characteristics, chemical composition and mass fraction of humic acids in terms of dry matter. The article presents the results of field trials on the effect of growth-stimulating organic fertilizer on hedge seedlings (elm and spirea) on the territory of the Astana Botanical Garden (Astana). Today, landscaping plays an important role in the development of any city. When choosing plants for hedges, it is necessary to take into account a number of indicators, such as unpretentiousness, stress resistance, adaptation to environmental conditions, etc. An important element in maintaining these factors is the use of additional feeding, in the form of biological preparations based on potassium humate. As a result of vegetation experiments, an effective effect of modified organic biopreparations (MOB with NPK, MOB with Mo) was established, in which a stimulating effect on the growth of new shoots and a significant increase in the biomass of elm seedlings was observed. Biological preparations also had a beneficial effect on spirea hedge bushes, which manifested itself in a significant increase in plant height.
