In supporting environmental management, which practice is commonly used to improve water infiltration and distribution?

• A. Fertilizer scheduling
• B. Drainage improvements
• C. Using wetting agents
• D. Pesticide applications

Answer: (C)

Improving water movement into and through soil is best achieved with wetting agents. These substances lower soil surface tension and help break down hydrophobic layers, allowing water to spread across the soil surface and infiltrate more readily. That leads to more uniform moisture in the root zone, better irrigation efficiency, and less runoff or dry patches. This is particularly useful in managed landscapes where soils can be dry, compacted, or hydrophobic. Fertilizer scheduling affects nutrient delivery, drainage improvements focus on removing excess water, and pesticide applications address pests—not water movement—so wetting agents most directly enhance infiltration and distribution.
