What term describes an irrigation system that applies water directly to the root zone?

• A. Misting System
• B. Drip Irrigation
• C. Overhead Sprinklers
• D. Flood Irrigation

Answer: (B)

Delivering water directly to the root zone is achieved with drip irrigation. This method uses emitters or soaker hoses placed at or near the base of the plant to release water slowly right where the roots can take it up, which makes water use highly efficient and reduces waste from evaporation or runoff. Drip systems are well suited for beds, containers, and shrubs because they provide precise, localized moisture and can be paired with mulches or soil sensors to maintain the right soil balance. In contrast, misting systems spray fine droplets into the air around the foliage, not into the soil where roots absorb water; overhead sprinklers water the plant canopy from above and often lose water to evaporation or leaf wetness; flood irrigation wets a large area of soil surface without targeting the root zone and wastes a lot of water.
