Enhancing the effect of phosphorus fertilizers, taking into account liming, taking into account liming in winter wheat cultivation on sod-podzolic soil

In long-term field experience on sod-podzolic heavy loamy soil, a significant return was revealed from the use of zinc, copper, magnesium fertilizers, the microbial preparation Bisolbifit together with phosphorus fertilizers in connection with liming in winter wheat crops. The beneficial effect of the studied techniques on grain quality, payback of fertilizers, consumption and utilization rate of phosphorus by plants was noted. On highly acidic, untreated soil with a high content of mobile aluminum (about 130 mg/kg), caused by the systematic introduction of physiologically acidic potassium chloride and ammonium nitrate, phosphorus fertilizers (on average for all the years of the study from 2017 to 2023) provided an increase in winter wheat yield by 69% at a dose of 11.5 tons of lime/ha of medium acid in the soil by 2.2 times, on slightly acidic (19.0 tons of lime/ha) – by 2.7 times, together with the use of trace elements and Bisolbifit – by 2.4 and 2.9 times from the average background level of nitrogen-potassium fertilizers (2.38 t/ha). At the same time, the payback of phosphorus fertilizers with winter wheat grain on slightly acidic soil from the introduction of micro fertilizers and Bisolbifit increased 2.7 times (up to 15.7 kg/kg), the protein content in the grain increased by 1.3%, phosphorus removal by 3.8 times (up to 70.7 kg/ha), the use of phosphorus by winter wheat plants by 2.7 times.
