What is fertigation?

Fertigation is a method of applying fertilizers through irrigation systems, allowing for more precise and efficient delivery of nutrients directly to the plants' root zones. This technique takes advantage of the existing irrigation infrastructure, distributing liquid fertilizers alongside water, which facilitates better uptake by plants. As a result, fertigation enhances nutrient absorption and can lead to increased crop yields.

The other options describe different agricultural practices: using organic compost contributes to soil health and fertility, farming without pesticides focuses on sustainable practices, and growing crops in greenhouses refers to controlled-environment cultivation. However, none of these options specifically involve the direct application of fertilizers through irrigation, which is the defining feature of fertigation.
