Abstract
Article is dedicated to the technology of obtaining organic-mineral liquid fertilizer and solid chemical meliorants from solid household waste with the presence of nitric acid.Articlebased on the data of nitric acid from solid household waste and the dynamics of decomposition with late participation, extensive information was given about the technology of making liquid fertilizers and chemical meliorants, and the technological scheme and its explanation were broadly explained based on the technological process for both experimental and production conditions. It was concluded that it is possible to buy high-quality liquid fertilizer rich in microelements and chemical ameliorant rich in organic substances based on solid household waste, late and nitric acid. According to the data obtained from the conducted agricultural tests, the purchased liquid fertilizer increases the productivity of plants, the chemical ameliorants in solid state improve the water-physical properties of the soil through the organic substances and gypsum contained in them. This has a positive effect on soil fertility indicators [1].
