This paper presents data on the production of magnesium-containing fertilizers based on the processing of serpentinite of Karakalpak deposit. Their chemical composition, physico-chemical properties (moisture content, volume weight, hygroscopicity, fluidity) were investigated. Chemical analyses of the obtained sample showed that the sample consists mainly of iron-13.7, magnesium-27.2, aluminium-5.66, nickel-7.66, silicon-1.30%. Also present are: calcium-1.25, manganese-0.578, cobalt-0.210 and titanium-0.0662% giving the material strength, heat and corrosion resistance. After the process of ammonization and packing to solid state, the magnesium-containing nitrogen fertilizer (three samples) consists of the sum of nutrient elements 39.5; 44.2 and 41.46%, in particular N-21.86; 22.5; 23.86%, of which 5.44; 4.74; 6.7% in ammonium form, Mg-18.3; 21.7; 17.4% respectively at pH 3; 4 and 5.
