What is one major consequence of decreased surface residue?

• A. Increased biodiversity
• B. Higher soil moisture retention
• C. Increased runoff
• D. Lower soil erosion

Answer: (C)

Decreased surface residue significantly contributes to increased runoff. When there is less residue on the soil surface, the protective layer that helps slow down rainfall and promote infiltration is diminished. This lack of vegetation and organic matter means that rainwater is more likely to flow quickly over the soil surface rather than being absorbed. As a result, the potential for water to evaporate or permeate into the soil diminishes, leading to more water being lost as surface runoff. Furthermore, increased runoff can lead to soil degradation and nutrient loss, affecting crop health and sustainability. Maintaining adequate surface residue is crucial in managing water infiltration and overall soil health.
