Abstract
A method for producing granular fertilizers based on pine sawdust containing ammonium nitrate is proposed. Physico-chemical properties of sawdust and fertilizers containing 20.0 wt.% nitrogen were studied. The effect of pretreatment of pine sawdust with 1 % wt. with a water solution of NaOH on the properties of granular fertilizers was explored. The results of a field trial on the cultivation of wheat varieties «Krasnoyarskaya 12» revealed the growth-stimulating effect of nitrogen-containing granular fertilizers in comparison with an unfertilized background. A more effective influenceon wheat yield of granular fertilizer fabricated from pine sawdust after their treatment with 1 % wt. with a water solution of NaOHThe achieved effect on 1,9 c/ha higher in comparison with thefertilizer based on original sawdust
