No-till farming (sometimes called zero tillage) is a way of growing crops from year to year without disturbing the soil through tillage. No-till increases the amount of water in the soil, decreases erosion, increases the amount and variety of life in and on the soil and it increases herbicide usage. There is evidence that repeated tillage destroys the soil resource base and causes adverse environmental impacts. Tillage degrades the fertility of soils, causes air and water pollution, intensifies drought stress, consumes fuel, and contributes to global warming. Today, farmers are expected to produce food in ever greater quantities. This is becoming more difficult to do in view of declining soil quality, which can be caused by soil tillage. It is becoming well known that no-till is an effective technique to reduce the degradation of soil. With this way of farming, crop residues or other organic amenities are retained on the soil surface and sowing/fertilising is done with minimal soil disturbance. This book gathers the latest research from around the globe in this field of study.Today, farmers are expected to produce food in ever greater quantities. This is becoming more difficult to do in view of declining soil quality, which can be caused by soil tillage.
