Q. Consider the following:
- Contour bunding
- Contour terracing
- Cover cropping
- Mixed farming
- Crop rotation
Which of the above measures can be adopted to prevent soil erosion?
Answer:
All of the above
Notes: Contour bunding, Contour terracing, regulated forestry, controlled grazing, cover cropping, mixed farming and crop rotation are some of the remedial measures which are often adopted to reduce soil erosion.
- Contour Bunding : It involves the placement of lines of stones along the natural rises of a landscape, and contour farming. These techniques help to capture and hold rainfall before it can become runoff.
- Cover Cropping : Cover Crop is planted to manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agro ecosystem–an ecological system managed and shaped by human.
- Mixed Farming : A system of farming which involves the growing of crops as well as the raising of livestock.
- Crop rotation : It is the growing of different crops in succession on a piece of land to avoid exhausting the soil and to control weeds, pest and diseases.
