abstract:
Wind erosion often occurs near the time of sowing of both spring and fall crops on the intensively-cultivated, sandy soils in Poland. The objectives of this study were to design and evaluate an integrated tillage system that could reduce the erosion hazard on the low-porosity, loamy sand soils that occupy large areas of crop land in Poland. Minimum tillage systems that preserve crop residues have been tested on these loamy sand soils. However, because of the low natural porosity, many of the crops traditionally grown on these soils, such as potatoes, sugar beets and barley, respond to minimum soil cultivation with low production. The integrated system modified the soil structure. It produced a larger fraction of non-erodible aggregates that had higher dry-aggregate stability at the soil surface when compared to the conventional tillage system. To achieve the first objective, an integrated tillage system was developed that performed plowing, pre-sowing, and sowing in a single tractor pass. Next, the integrated system was compared to other tillage systems to determine its relative effects on tillage energy distribution, soil structure and potential wind erosion.
