What is the term for the maximum amount of water the soil can absorb?

• A. Infiltration capacity
• B. Infiltration
• C. Insecticide
• D. Igneous rock

Answer: (A)

The main idea here is the rate limit at which soil can take in water under given conditions. That limit is called infiltration capacity—the maximum infiltration rate the soil can achieve. It depends on factors like soil texture and structure, porosity, surface cover, and how moist the soil already is. If rainfall is lighter than this capacity, water infiltrates at the rainfall rate. If rainfall is heavier, the soil can’t take in water fast enough, so excess water becomes surface runoff. Infiltration describes the actual process of water entering the soil, but not the maximum rate. Insecticide and igneous rock are unrelated to soil water absorption.
