Accepted Answer

No-till farming (also called zero tillage or direct drilling) is a way of growing crops or pasture from year to year without disturbing the soil through tillage. No-till is an agricultural technique which increases the amount of water that infiltrates into the soil and increases organic matter retention and cycling of nutrients in the soil.Gypsum improves the ability of soil to drain and not become waterlogged thus increasing water-use efficiency of crops.
