Correct option is C
Terrace Cultivation is the best method for preventing soil erosion on steep slopes. By creating
stepped levels or terraces along the slope, it slows down water runoff and prevents the washing away of
fertile topsoil. This method is particularly effective in hilly and mountainous regions, where soil erosion
from heavy rains is a significant challenge. The terraces not only help in soil conservation but also
increase water retention, making the land more suitable for agriculture.
Information Booster:
· Terrace cultivation helps slow down water runoff, reducing soil loss.
· It allows farming on hilly terrain by creating flat surfaces.
· The method improves water absorption, reducing wastage.
· Terrace farming supports sustainable agriculture in mountainous regions.
· Widely practiced in regions like the Himalayas and the Andes for soil conservation.
Additional Knowledge:
·
Mulching: Involves covering soil with organic materials like straw or leaves. It helps reduce evaporation and moderate soil temperature, preventing erosion on flat or gentle slopes.
·
Shelter Belts: Rows of trees or shrubs planted around fields to reduce wind speed and prevent wind erosion. Effective mainly in plains and semi-arid regions.
·
Inter-cropping: Growing two or more crops simultaneously on the same field. While it helps improve soil fertility and reduce erosion, it is not ideal for steep slopes.
