THE EVALUATION OF FERTILIZER MADE FROM VEGETABLE WASTE FROM THE FOOD MARKETS IN ULAANBAATAR, MONGOLIA

There is a lot of organic waste from food markets that can be used to make compost. Every day, we throw away large amounts of fruit and vegetable waste, which is part of the waste from these markets. Since waste is a major issue in our country today, this research was conducted with the aim of making a significant contribution to solving this problem. As part of this work, the possibility of reusing waste from large food markets was explored. The aim was to study the effect of fertilizers made from fruit and vegetable waste on the soil. Food waste fertilizer was used for 60 days. During the composting process, the quality of the compost was checked at 21, 45, and 60 days. The processed fertilizer was tested in the soil in 3 variants and 4 repetitions. According to our research, it is possible to make compost fertilizer from vegetable waste in 1-2 months. According to the survey results, it was possible to collect 1,826.7 tons of fruit and waste per day from a large number of vegetable markets, which could be used to make 657,621.0 tons of compost per year. Intestinal bacilli were found at 21 days of composting with vegetable waste, indicating that the compost was not fully mature, and compost was fully mature at 60 days. In our country, it was possible to make compost fertilizer from food waste from food markets in 60 days and apply it to the soil at the norm of 15-20 tons.
