Use of anhydrous ammonia in improving the nitrogen utilization effi ciency in winter wheat plantings
Keywords: anhydrous ammonia, ammonia nitrate, fertilizer elements, winter wheat, grain quality, yield
AbstractAim. To study the specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, yield and quality of winter wheat grain compared to granular nitrogen fertilizers in order to elaborate intensive produc- tion technologies. Methods. The content of mineral nitrogen in the soil was determined according to DSTU 4729-2007, the content of movable phosphorus and potassium forms − by Chirikov’s method (DSTU 4115- 2002). The abundance of the main ecological and trophic groups was registered after sowing the soil suspen- sion on dense nutrient media. The concentration of total nitrogen, phosphorus, and potassium in plant samples was determined according to the measurement procedure 31-497058-019-2005. The quality indices of grain, i.e. protein and crude fi ber content as well as general glassiness were determined using Inframatic 8600 NIR analyzer, Perten Instruments AB (Sweden). Results. The specifi cities of the effect of anhydrous ammonia on the indices of soil fertility, the use of nutrients from fertilizers and soil, the yield and quality of winter wheat grain were demonstrated. Conclusions. The advantages of anhydrous ammonia application prior to sowing compared to the use of ammonia nitrate, traditional for Ukrainian agriculture after the growing season, were established.
