Abstract

The invention relates to the production of chlorine-free potash fertilizers by displacing potassium chloride and urea with additives. The purpose of the invention is to increase the growth of plants and reduce the content of chlorine ions in the soil. The goal is achieved by the fact that in the method of producing chlorine-free potassium fertilizers, including mixing potassium chloride and urea with a calcium-containing reagent, spent mycelium is used as a calcium-containing reagent and mixing is carried out in the presence of boric, sulfuric acids, followed by the introduction of potassium permanganate. 1 hp f-ly, 2 tab.

Description

The invention relates to the production of chlorine-free potash fertilizers by mixing potassium chloride and urea with additives and can be used in agriculture.

The purpose of the invention is to increase the growth of plants and reduce the content of chlorine ions in the soil.

Example. Spent mycelium composition presented in table. 1, is treated with a dilute sulfuric acid concentration of 5-10% to obtain a homogeneous mixture. Boric acid, urea, and potassium chloride are introduced into the mixture and stirred until a homogeneous mass is obtained. Potassium permanganate is then added. If necessary, the fertilizer is dried. The estimated rate of fertilizer 150-250 g per 10 liters of water; for flowers - 50-100 g per 10 liters of water.

In tab. 1 shows the chemical composition of the treated micelle.

Spent micelium is a by-product in the production of food citric acid at the Spitak Sugar Combine of the State Agricultural Committee of the Armenian SSR.

In tab. 2 shows the rationale for the selected component ratios.

From the analysis of table. 2, it follows that the implementation of the process in the stated ratios of the ratios (examples 1–3) makes it possible to reduce the SGV content in the soil after fertilizer application from 1600 to 200–230 mg / l, to increase germination from 1–4 to 6–10 pcs, from one bush and increase the life of cut flowers from 3 to 6-7 days. In addition, the use of waste allows to obtain a fertilizer containing trace elements in the amount of 3.5-4.2% in the form of Zn, Cu, R20i "

A decrease or increase in the number of input components outside the specified ratios (examples 4 and 5) leads to an increase in the chlorine ion content in the soil, a decrease in shoot formation and a longer life of the cut flowers.

The economic feasibility of the proposed method is associated with the use of production wastes, the production of fertilizer containing trace elements and the possibility of the influence of fertilizers on the agrochemical properties of the soil.
