<description xml:lang='en' descriptionType='Abstract'><p>The paper proposes an environmentally friendly method for phosphogypsum processing into N,Ca,S,P-fertilizers. The liquid complex mineral fertilizer was obtained by treating phosphogypsum with an ammonium nitrate solution. The dependence of the content of Ca2+, SO42-, NO3- ions in the temperature range of 20-80&deg;C at the ratio CaSO4:NH4NO3= 1:0.5 was studied. The optimal temperature for the fertilizer obtaining was established at 60&deg;C. It was obtained a complex liquid N,Ca,S,P-fertilizer with the content of nutrients (wt. %) N:Ca:S:P= 56:26:12:6 in the dry product, and 16.8:3.6:7.8:1.8 in the liquid phase. The obtained fertilizer increased the yield of radish by 7.16% compared to the control. The advantage of the proposed method is reducing the cost of the fertilizer, increasing its nutritional value, and obtaining useful products from the waste.</p></description>
