Fertigation refers to the practice of

• A. Applying fertilizer through irrigation water
• B. Injecting water into fertilizer tank
• C. Soaking soil before planting
• D. Applying fertilizer by foliage spray

Answer: (A)

Fertigation means delivering soluble fertilizer through the irrigation water. This combines nutrient application with irrigation, so nutrients are carried by the water and delivered directly to the root zone. It allows precise control of what rate and when crops receive nutrients, improves uptake, and reduces losses from leaching or volatilization. It’s commonly used with drip or other micro-irrigation systems in greenhouses and fields. The other ideas describe different practices: injecting water into a fertilizer tank is about how an injection system is set up, not the act of applying nutrients with irrigation; soaking soil before planting is pre-plant soil conditioning; applying fertilizer by foliage spray is foliar feeding, which targets leaves rather than delivering nutrients through the root zone via irrigation.
