. What do you understand by crop rotation
Giving a suitable example, explain how this practice is beneficial to the farmers.
The practice of successive cultivation of different crops in a specific manner in the same field is known as crop rotation.
For example a farmer plants corn crops and after harvesting corn he can plant legumes because corn absorbs nitrogen from the field and legumes return that nitrogen back to the field.
Crop rotation is beneficial for farmers for mainly following reasons
- Plants that fix nitrogen, such as peas and other legumes, enhance the quality of soil along with high productivity.
- If shallow-rooted and deep-rooted plants are grown in an alternated pattern in a given area, they draw nutrients from the soil at different depths and increase the fertility of soil.
- Farmers practice this technique to minimize soil erosion and to increase water efficiency.
- Farmers who practice crop rotation technique do not need to let fields barren (crop-free)
Hence, production of successive cultivation of different crops in a particular manner in the same field is known as crop rotation.
