Efficient irrigation

Definition

Efficient irrigation refers to the application of water resources in agriculture in a way that maximizes crop yield while minimizing water waste. This method involves using techniques and technologies that deliver water directly to the plant roots, ensuring optimal moisture levels and reducing runoff or evaporation. The importance of efficient irrigation lies in its role in sustainable agricultural practices and food security, as it allows farmers to use limited water supplies effectively, especially in regions facing water scarcity.
