Question
Contour farming is :
The correct answer is
A simple conservation practice of farming operation
Contour Farming Explained
Contour farming is an agricultural technique where soil conservation is prioritized by performing farming operations, like tilling and planting, along the natural contours of the land. These contours are lines of elevation that run across a slope.
Why Contour Farming Works
By plowing and planting parallel to these contour lines, farmers create a series of small ridges and ditches. These act as barriers that slow down rainwater runoff. This process:
- Reduces soil erosion by preventing water from gaining momentum down the slope.
- Increases water infiltration into the soil, improving moisture availability for crops.
- Helps prevent the formation of gullies.
Contour Farming vs. Other Practices
Contour farming is distinct from other agricultural methods:
- It differs from mulching, which involves covering the soil surface.
- It is not a small dam structure built for water retention.
- It is separate from weeding practices aimed at removing unwanted plants.
Essentially, contour farming is a fundamental conservation practice integrated directly into the farming operation itself.
