Subsurface irrigation is a method of watering crops where water is delivered directly to the root zone through buried pipes or tubes. This technique minimizes evaporation and runoff, making it an efficient way to use water. It is particularly beneficial in arid regions where water conservation is crucial for agriculture. This system can improve plant health by providing consistent moisture and reducing weed growth. Subsurface irrigation is often used in conjunction with drip irrigation systems, allowing for precise control over water application. It is suitable for various crops, including vegetables and fruit trees.
