Fertigation delivers nutrients through what system?

• A. Irrigation system
• B. Foliar spray
• C. Soil drench
• D. Hydroponic reservoir

Answer: (A)

Fertigation mixes fertilizer into the irrigation water so nutrients travel to the plant roots as the water moves through the irrigation system. This approach is common with drip or sprinkler setups and allows precise nutrient dosing, uniform distribution, and efficient use of water. It isn’t a foliar spray, which feeds leaves; nor is it a soil drench, which involves applying solution directly to the soil rather than through the irrigation lines. It isn’t a hydroponic reservoir, which is simply a storage/replacement source for a nutrient solution in hydroponics. The delivery through an irrigation system is what defines fertigation.
