Which type of erosion is caused by the impact of raindrops on exposed soil?
Answer: Splash erosion
Splash erosion occurs when raindrop impact detaches and disperses soil particles.
What is the primary purpose of a contour bund in soil conservation?
Answer: Intercept and slow runoff on slopes
Contour bunds are earthen embankments built along the contour to intercept runoff and reduce erosion.
The Universal Soil Loss Equation (USLE) factor 'C' represents which parameter?
Answer: Crop management
The C factor in USLE represents the cover and management factor related to cropping and tillage practices.
Which irrigation method has the highest water use efficiency in field crops?
Answer: Drip irrigation
Drip irrigation delivers water directly to the root zone, typically achieving 90–95% efficiency.
What does the term 'field capacity' refer to in soil-water relationships?
Answer: Water content after free drainage has ceased
Field capacity is the soil moisture content remaining after excess water has drained away under gravity.
A grassed waterway is used primarily to:
Answer: Safely convey runoff without causing erosion
Grassed waterways are vegetated channels designed to carry concentrated runoff at non-erosive velocities.
