Abstract: The article presents the research results of productivity and technological qualities of sugar beet roots. Regularities in change of efficiency and technological qualities of sugar beet roots at different harvest time are revealed. The best harvest time is found out. Введение. Локальный мониторинг на репер-ных участках, заложенных на сельскохозяй-ственных угодьях, представляет собой систему наблюдений за состоянием пашни для своевре-менного выявления и прогнозирования измене-ний плодородия почвы, качества и ко… Show more

The article presents for the first time the results of using organic substances belonging to the category of industrial waste as fertilizers for agricultural crops. The dairy industry has waste (hereinafter referred to as cake) generated during the cleaning of milk pipes and requiring additional costs for their disposal. Biogas plant products (hereinafter referred to as biofertilizer) obtained from fresh chicken manure by fermentation in an anaerobic environment are also promising as fertilizer for agricultural crops. Biofertilizer and cake were applied superficially at different plots at doses of 3 kg/m2 (30 t/ha), 6 kg/m2 (60 t/ha) and 9 kg/m2 (90 t/ha). The potato tubers of the ‘Gala’ variety of German selection were planted. It was found that the higher the dose of the used substances, the greater the yield of potatoes. The yield increase in the variant of 30 t/ha of cake was 5.9 t/ha of potato tubers, 60 t/ha of cake - 11.3 t/ha, and in the variant of 90 t/ha of cake - 15.5 t/ha. The use of biofertilizers also caused an increase in yield. The use of waste as fertilizers enhances the biological activity of soils, increases the content of mobile nutrients of plants of light gray forest soil.

Relevance. The issues of reproduction of fertility of light gray forest soils of the forest-steppe zone and utilization of poultry industry waste as organic fertilizers are interrelated and are very relevant. Methods. The experiments studied the effect of one-time application of various doses (15, 30, 50 t/ha) of chicken manure, chicken manure compost and local organic fertilizers (sapropel and peat) on crop yields, and the aftereffect of fertilizers on the main indicators of soil fertility — amount of humus, nitrate nitrogen, phosphorus and potassium. The variants of the experiments were investigated sixfold. The Federal State Center of Agrochemical Service "Chuvashsky" was involved in laboratory analyses of soils and crop production. Mеthods of analysis of soil samples and crop production are generally accepted in agrochemical science.Results. Organic fertilizers for three years of research were introduced into the soil only once at the beginning of the experiment in doses of 15, 30 and 50 t/ha, and their effect on the yield and quality of crop production (potato tubers, spring wheat grains and peas) in 2020–2022 was positive. The agrochemical properties of the arable soil layer in the variants with the use of organic fertilizers have significantly improved. The nitrate content in the products in variants with doses of chicken manure and compost of 50 t/ha or more approached the critical level. Local fertilizers (sapropel and peat) at a dose of 30 t/ha, chicken manure and compost at a dose of 15 t/ha are good organic fertilizers with a long aftereffect.
