Changes in agrochemical indicators of light gray forest soil and productivity of meadow clover depending on the level of mineral nutrition against the background of the aftereffect of liming in the conditions of the South-East of the Volga-Vyatka region
The research was carried out in a long-term stationary experiment, launched in 1978 on light gray forest soil in the conditions of the Nizhny Novgorod region. In 2020-2021, the effectiveness of various doses of mineral fertilizers (N0P0K0, N15P40K60, N30P80K120, N45P120K180) was studied against the...

| description | The research was carried out in a long-term stationary experiment, launched in 1978 on light gray forest soil in the conditions of the Nizhny Novgorod region. In 2020-2021, the effectiveness of various doses of mineral fertilizers (N0P0K0, N15P40K60, N30P80K120, N45P120K180) was studied against the background of liming when laying the experiment (in doses 0; 0.5;1.0;1.5; 2.0; 2.5 of hydrolytic acidity) on the yield of meadow clover Martum of the 1st and 2nd years of use. It has been established that the studied lime doses introduced in 1978, by August 2021 had not affected the change in agrochemical parameters of light gray forest soil (acidity, content of mobile forms of phosphorus and potassium, humus) and the yield of meadow clover of the 1st and 2nd year of use. A long-term use (1978-2021) of single and double doses of mineral fertilizers did not provide the accumulation of humus, mobile forms of phosphorus and potassium as compared to their initial content in arable layer of light gray forest soil. Increased content of mobile forms of phosphorus and potassium (Р2О5 per 34.1 mg/kg, К2О per 22.3 mg/kg) was observed by long-term application of three-fold doses of mineral fertilizers. Application of mineral fertilizers in a dose of N45P120K180 enabled to obtain 36.5 and 37.9 t/ha of green mass during the 1st and the 2nd year of use and the highest total yield of 74.4 t/ha that is 12.0-22.2 t/ha higher than the control and all the rest variants of mineral fertilizers application. |
