Aftereffect of liming on the yield of seeded grass stand in conditions of sod-podzolic soil

The article presents the results of a long-term agrochemical experiment laid out in 1935 on sod-podzolic medium loamy soil. The objective of the study was to evaluate the aftereffect of different lime doses on agrochemical parameters and productivity of sown grass stand under conditions of haymaking with differentiated application of fertilizers. The yield was recorded twice during the growing season on 10 m2 plots; the data cover the period 1994–2024. The study established that the aftereffect of liming at doses of 36–60 t/ha CaCO3 provides optimal conditions for the formation of a sustainable yield level of multicomponent cereal grass stand while reducing soil acidity and simultaneously improving its agrochemical condition. The effectiveness of lime application is maintained after more than eight decades, which indicates the need to take into account the residual effect of ameliorants in long-term agroecological planning.
