Estimation of the efficiency of application of complicated-mixed mineral fertilizers in the conditions of Perm region

Abstract

The efficiency of using complex-mixed fertilizers FertiM N9P14S10, FertiM N10P10K10S9, FertiM N16P8K8S12, FertiM N20P10K10S12 produced by Terminal-Lysva LLC on spring wheat of the Gornouralskaya variety and spring rape of the Podmoskovny variety has been studied. Fertilizers of Terminal-Lysva LLC were compared with traditional ammonium nitrate and complex Azophos (N16P-16K16) fertilizers. The influence of fertilizers on the yield and quality of wheat products has been studied. The maximum wheat grain yield of 4,0 t/ha was obtained with the introduction of FertiM N20P10K10S12, which is 0,3 t/ha higher than with the application of complex fertilizer N16P16K16 and 0,8 t/ha higher than in the control variant. The use of the complete mineral fertilizer FertiM N10P10K10S9 and FertiM N20P10K10S12 ensured a higher crop yield (by 0,3-0,5 t / ha) than the application of nitrogen (ammonium nitrate) or nitrogen-phosphorus fertilizers (FertiM N9P14S10). An increase in the content of crude protein in grain from 9.1 to 10.9% was noted with the addition of FertiM N10P10K10S9. The yield of spring rapeseed with FertiM application increased by 0.2-0.3 t / ha. The use of FertiM significantly increased the content of crude protein in rapeseed, and tendencies of an increase in crude fat and total phosphorus were noted. The results were obtained on the effect of complex-mixed fertilizers FertiM on soil fertility indicators. The application of complex-mixed fertilizers FertiM increased the content of mineral nitrogen in the soil by 1,1-1,3 times. No deterioration in the indicators of the soil-absorbing complex was observed.
