Drip irrigation
open-in-new
<p> Drip irrigation or trickle irrigation is a type of <a href="/facts/Micro-irrigation/uCBBH6kv">micro-irrigation</a> system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the <a href="/facts/Rhizosphere/s4ML8x0C">root zone</a> and minimize evaporation. Drip irrigation systems distribute water through a network of <a href="/facts/Valve/EwgqAwlJ">valves</a>, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as <a href="/facts/Surface_irrigation/USY5TRWw">surface irrigation</a> or sprinkler irrigation. </p><p>As of 2023, 3% of the world's farmers use drip irrigation. </p>
