Abstract

Differential offline mineral fertilization of elementary field sectors is one of primary economical and ecological aspects of precision farming. Application of this technologies allows significantly reducing expenses for ammonia nitrate, i.e. fertilization depends on anticipated crop capacity and demand for summer wheat and ensures optimal content of soil nitrogen. It was proven that differential fertilization by ammonia nitrate simultaneously with sowing for anticipated crop capacity of 3.0 t/ha with spatially variable content of nitrate nitrogen of 25% in the soil layer of 0-40 cm, its low and moderate availability (8.1-17.9 mg/kg of soil) reduces the amount of fertilizer by 21.1-50.5% and reduces production expenses by 3.4-4.1% vs. traditional fertilization method with averaged amount along the field.
