Irrigation techniques are methods used to supply water to crops and plants to enhance growth and productivity. Common techniques include drip irrigation, which delivers water directly to the roots through a network of tubes, and sprinkler systems, which spray water over the plants like rain. These methods help conserve water and ensure that plants receive the right amount of moisture. Another technique is surface irrigation, where water flows over the soil surface to reach the plants. This method is often used in fields with gentle slopes. Subsurface irrigation involves placing pipes below the soil surface to provide moisture directly to the root zone, promoting efficient water use.
