Structural Amelioration of Soils for Sustainable Land Management

Abstract

The aim of this study is to determine the effects of structural soil restoration on the buffering capacities of these soils, their productivity, and the efficiency of their use as a basis for sustainable management. Based on a review of literature sources and our own experimental research, the proposed article shows the possibility of improving the buffering capacities of sod-podzolic cohesive sandy soils through the use of structural amelioration as an effective measure to protect them from degradation and ensure their resilience to climate change. The use of structural ameliorants (clay and peat) in the studied soils improves the granulometric composition, has a positive effect on the pH-buffering capacities, and contributes to optimizing the moisture capacity of soil. It was found that the efficiency of the application of structural amelioration on sod-podzolic cohesive sandy soils increases significantly with the local application method (e.g., clay in a dose of 10 t/ha or a combined application of clay in a dose of 2 t/ha with lowland peat in a dose of 3 t/ha). The largest yield increase in winter wheat (27.2%) was achieved by the local application of 2 t/ha of clay combined with peat in a dose of 3 t/ha.
