CCA Soil and Water Management

Question 1

What is the primary benefit of conservation tillage in soil management?

Accepted Answer

Reduces soil erosion

Answer

Conservation tillage helps reduce soil erosion by maintaining crop residue on the soil surface, which protects the soil from wind and water erosion.

Question 2

Which soil texture typically has the highest water-holding capacity?

Accepted Answer

Clay

Answer

Clay soils have a high water-holding capacity due to their small particle size and high surface area, which allows them to retain more moisture.

Question 3

What is the main reason for implementing contour farming?

Accepted Answer

Reduces soil erosion

Answer

Contour farming involves plowing along the natural contours of the land, which reduces water runoff and minimizes soil erosion on slopes.

Question 4

Which of the following best describes field capacity?

Accepted Answer

Moisture remaining after drainage

Answer

Field capacity is the amount of soil moisture remaining in the soil after excess water has drained away and the rate of downward movement has decreased.

Question 5

Why is organic matter important in soil?

Accepted Answer

Improves soil structure and fertility

Answer

Organic matter improves soil structure, increases nutrient availability, and enhances water retention, making it vital for soil health and productivity.
