What does fertigation mean in agricultural practice?

• A. Applying fertilizer through irrigation water.
• B. Seeding crops through irrigation water.
• C. Scheduling irrigation based on fertilizer price.
• D. Mixing fertilizer with pesticides.

Answer: (A)

Fertigation means applying fertilizer through irrigation water. Nutrients are dissolved in the irrigation supply and delivered directly to the root zone as water is applied, combining fertilization with irrigation. This approach allows precise, timely nutrient delivery and can improve uptake while reducing losses to runoff or deep percolation. It works especially well with drip or micro-sprinkler systems, where nutrients can be metered and timed to match crop needs. If pesticides are added, that would be a different practice (often called chemigation), not fertigation.
