Soil productivity is one of the most important factors worldwide for agricultural production. Improving soil quality with the use of conservation tillage can preserve soil productivity. Tillage systems are used for many agricultural purposes ranging from weed control to the incorporation of crop residue and amendments, and ultimately are used to prepare a suitable seed bed for better seed germination. Conservation tillage conserves water, improves soil and water quality, lowers input costs, and reduces labor. Therefore, conservation tillage systems must be assessed and evaluated to control negative impacts on soil and water quality, while promoting soil productivity. The major objectives of the study are to evaluate the effect of tillage systems (strip tillage, chisel plow, and no-tillage) on soil quality indices and time of nitrogen application, and tillage systems on ground water quality and use efficiency.
