Abstract
The research is based on the study of the effect of solid organic fertilizers based on cattle manure of different storage life on the yield of spring wheat. The studies were carried out in 2017-2018 at RUSKOM-Agro LLC in Omsk Region. It was established that 3.1-7.2 kg of nitrogen, 2.1-7.2 kg of phosphorus and 2.1-3.5 kg of potassium are introduced from each ton of organic fertilizer. The most effective active dose is 60 t/ha (with a storage duration of 8 months) – the increase made 1.51 t/ha, with a yield in the control version – 2.04 t/ha. The best dose in the afterinfluence was 60 t/ha (with a storage duration of 10 months) – the increase made 1.24 t/ha, with a yield in the control version – 2.09 t/ha. The cost recovery of the applied fertilizer unit (1 ton of manure) was the highest using 40 t/ha per year in action and 20-60 t/ha in the afterinfluence with a storage duration of 12 months.
