Mineral and raw resources and poultry waste to increase soil fertility

Abstract

The purpose of the work was to analyze the use of mineral resources and poultry waste to increase soil fertility in the Tyumen region. According to statistics for 2020 in Russia 45156,3 tons of waste was generated from agriculture, forestry, hunting, fishing and fish farming. On the territory of the Tyumen region 1200 tons of poultry droppings are formed per day. The volume of accumulation is 432,000 tons per year. At the same time, poultry droppings is a source of greenhouse gases, their amount can be: CO₂ – 21,5 million m³, methane – 12,9 million m³ per year. Diatomite is a sedimentary rock consisting of fossilized shells of diatoms, and is a fine powder of gray color. Due to its unique chemical and biological properties, diatomite is widely used in many areas of agriculture as an excellent adsorbent, fertilizer, top dressing for animals and poultry, an environmentally friendly contact insecticide for pest control of grain, fruit and ornamental plants. In order to restore the lost soil fertility in the region (0,6 %, or 2032,2 hectares per year), it is necessary to carry out soil protection measures, as well as the introduction of mineral and organic fertilizers (11,7 million tons of organic fertilizers annually for 15 years). The presence of a large amount of mineral resources and poultry droppings in the Tyumen region makes it possible for researchers to develop the composition and technologies for creating organomineral fertilizers. The implementation of the project based on the technology of using modified diatomite and various types of poultry waste will reduce the amount of waste, reduce the hazard class of bird droppings, the environmental burden of poultry farming on the environment, as well as increase the biological safety and productivity of arable land.
