What does the term 'micro-irrigation' refer to?

The term 'micro-irrigation' specifically refers to a method that delivers water in small quantities directly to the root zone of plants. This technique is designed to optimize water use efficiency by minimizing evaporation and runoff. It utilizes systems such as drip or micro-sprinkler irrigation, ensuring that water is precisely applied where it is most needed, which is critical for plant health and growth. By focusing on the root zone, micro-irrigation not only conserves water but also encourages deeper root development, resulting in better crop yields and reducing the risk of plant stress during dry conditions.

While other methods of irrigation may apply large amounts of water or target broader areas, they do not achieve the same level of water efficiency and targeted application as micro-irrigation. This makes micro-irrigation a crucial practice, especially in regions where water scarcity is a concern.
