Структурно-агрегатный состав дерново-подзолистой легкосуглинистой почвы при сочетании различных вариантов системы удобрения с различными способами обработки почвы | Structural and aggregate composition of soddy-podzolic light loam soils at various variants of fertilization system with various methods of soil tillage

In the conditions of the Republic of Belarus there were presented research findings on changes in structural aggregate composition of sod-podzolic light loamy soil affected by various systems of fertilizer application and tillage methods. It has been found that applying manure-mineral fertilizers together with minimum tillage and direct seeding improves the structural status of sod-podzolic light loamy soil. Over the years of studies it was found that mineral fertilizer system eventually leads to degradation of soil structure, since the coefficient of structure was less in comparison with other systems of fertilizers and control. Only in direct seeding there was marked a significant difference compared with the control. Higher values of the coefficients of soil structure in comparison with other years of research were obtained in 2008, which was apparently due to the manifested action of aftereffect of organic and mineral systems in conjunction with the combined treatments of soil.
