Fertigation refers to delivering fertilizer through which method?

• A. Delivering fertilizer by hand
• B. Injecting pesticides into irrigation water
• C. Spreading fertilizer on bare soil
• D. Delivering fertilizer through an irrigation system

Answer: (D)

Fertigation combines fertilization with irrigation by delivering soluble fertilizer directly through the irrigation system. This lets you inject nutrients into the irrigation lines and distribute them with the water to the root zone, enabling precise control of both timing and amount. Using a fertigator or injector with drip or other irrigation setups provides uniform delivery, improves nutrient uptake, and reduces waste and losses compared to broadcast methods. It’s especially effective in greenhouses with substrate growing, where nutrient needs can be closely matched to plant growth stages. By contrast, applying fertilizer by hand is manual and less precise, spreading on bare soil is uneven and inefficient, and injecting pesticides into irrigation water is chemigation, not fertigation.
