Tillage techniques refer to the methods used to prepare soil for planting crops. These techniques can include plowing, harrowing, and cultivating, which help to aerate the soil, control weeds, and incorporate organic matter. Different methods can impact soil structure, moisture retention, and nutrient availability. Conventional tillage involves turning over the soil completely, while conservation tillage minimizes soil disturbance to protect soil health and reduce erosion. No-till farming is a popular conservation method that leaves the soil undisturbed, promoting better water retention and reducing the need for chemical inputs. Each technique has its advantages and is chosen based on specific farming goals.
