Clayey soil’s physical and chemical traits are dependent on many properties – clay-mineral and grain-size composition, hydrological properties, relief, soil tillage, crop rotation. The study is carried out in a long-term monitoring field Poķi at the Research and Study farm “Pēterlauki” of the Faculty of Agriculture of Latvia University of Life Sciences and Technologies, where uniform soil tillage is used since 2009. Three different crop rotation variants in two soil tillage variants (traditional (mould-board ploughing) and reduced (disk harrowing)) were studied. The goal of the study was to identify the influence of long-term uniform soil tillage on clay mineral composition and soil plasticity. First results showed that reduced soil tillage has influence on clay mineral composition and also on soil plasticity.
