Abstract
Abstract In Russia 45156.3 tons of waste were generated from agriculture, forestry, hunting, fishing and fish farming according to statistics for 2020. 1200 tons of manure are formed per day in Tyumen region. The volume of accumulation of such manure is 432,000 tons per year. But at the same time, manure is a source of greenhouse gases, their amount can be: CO2 – 21.5 million м 3 , methane – 12.9 million м 3 per year. Due to its unique chemical and biological properties, diatomite is widely used in many areas of agriculture. It can be used as an excellent adsorbent, fertilizer, food additive for animals and birds, an environmentally friendly contact insecticide for pest control of grain, fruit and ornamental plants. To restore the lost fertility (0.6% per year (2032.2 hectares), it is necessary to carry out soil protection measures, as well as to add mineral and organic fertilizers to the soil (11.7 million tons of organic fertilizers annually for 15 years). The availability of a large amount of mineral resources and bird manure makes it possible for researchers to develop the composition and technologies to create organomineral fertilizers.
