In some areas, the intensification of agriculture, and the use of conventional farming practices have caused soil nutrient levels to decline. Using stubble from the previous year's crop helps protect growing plants and soil from erosion by wind and water. This increases soil moisture, infiltration, and retention, while assisting to maintain stable nutrient levels. Currently, there is a renewed appreciation among farmers for the nutrient value of cattle and hog manure, and many new approaches are being explored in search of the optimum methods of incorporating this valuable resource into the soil.
