Improving the system of fertilizer barley in modern conditions

The article presents the results of research conducted under integrated agricultural production center Michurin Vavozh Dis- trict of Udmurt Republic and JSC Instructional farm “July” of the Izhevsk State Agricultural Academy. Found out that barley, which cultivated in sod-podzolic soils, responds positively to change agrochemical parameters. With increasing content of organic matter, available phosphorus and exchangeable potassium in the soil and with a decrease soil acidity naturally barley increases grain yield. In the long-term field experiment, based in 1979 on sod-podzolic soil various fertilizers systems have been studied. On average over years of research on the background of systematic liming the barley showed higher responsive- ness to mineral fertilizers compared to organic. Herewith grain yield increase compared to control on average in II, III and IV crop rotations was 1.57 t/ha. Average crop yield increase from the systematic use of organic-mineral fertilizer system over these years was 1.89 t/ha. A positive effect of organic-mineral fertilizer system was found out onto the properties of sod-podzolic soil: рНКСl increased by 1.1–1.7 units, mobile phosphorus content increased by 149–202 mg/kg, and exchangeable potassium — at 35–119 mg/kg relative to the control. Upon cancellation of liming the soil movable aluminum accumulates, which adversely affects the yield of barley. For yield of barley not less than 2 t/ha when cultivation on sod-podzolic soils of the Middle Urals, recommended minimum doses of application: N25P25K20 kg/ha.
