The invention relates to the production of chlorine-free fertilizer fertilizers by the interaction of potassium chloride with allowances that can be used for growing plants.

The aim of the invention is to increase the growth of plants and a decrease in the content of chlorine ionosis in the soil.

Example. Perlite rock after fine grinding pbrabtstyvryut in a solution of potassium alkali with ochetratsmey 200-250 g / l CgO at 120-150 ° C and for 0.5-1.0 h, W: T - (8-10): 1. On the resulting the suspension is exposed to a solution of sulfuric acid with a concentration of 10-25% and an excess of 10-15% of the total mass. The resulting gel mass is used as component e ;; fertilizer.

at intervals of 6–8 to 2–3 days and an increase in chlorine content from 170 to 1,600 mg / l at the level of the prototype.

The economic efficiency of the proposed method for producing chlorine-free potassium fertilizer is due to the possibility of affecting the soil and improving its properties by removing chlorine / chlorine, increasing the efficiency of fertilizer and enriching with microelements.

Claims (2)

Claim 1. Method for producing chlorine-free potassium fertilizer, which includes mixing potassium chloride with additives, characterized in that, in order to increase plant growth and reduce the content of chlorine ions in the soil, a product of sequential alkaline acid treatment of perlite is used as an additive Mixtures are carried out in the presence of boric acid, followed by the introduction of potassium permanganate. 2. The method according to claim 1, characterized in that the starting components are taken in the following ratio, wt%; potassium chloride 16.0-20.0; alkaline acid product of perlite rock 77.0-83.0; boric acid 0.5-1.5; potassium permanganate 0.5-1.5.
