Fertilizer injection is an efficient and approximate way of applying fertilizer.

• A. True
• B. False
• C. Not Efficient
• D. Requires Calibration

Answer: (A)

Fertigation delivers nutrients by injecting soluble fertilizer into irrigation water, so nutrients travel with the water directly to the root zone. This setup streamlines nutrient delivery, reducing labor and timing constraints, and helps minimize losses from volatilization or runoff when managed properly, which makes it an efficient way to apply fertilizer. At the same time, the exact amount each plant receives can vary due to differences in irrigation flow, pump pressure, emitter spacing, and soil conditions, so the distribution is not perfectly uniform; that’s why the method is considered approximate. Regular calibration and monitoring of the injector and irrigation system can improve accuracy, but the approach remains inherently approximate by nature.
