Correct Answer: Option E
Explanation:
Explanation:
The bush fallow system is a traditional method of farming where a piece of land is left uncultivated (fallowed) for several years so that it can regain its fertility naturally through the growth of natural vegetation.
Key Features of the Bush Fallow System:
- Practiced mostly in subsistence agriculture.
- Common in areas with low population pressure.
- The land is cleared and farmed for a few years, then abandoned to allow natural processes to restore soil nutrients.
- After a few years (e.g., 5 years, as in the question), the farmer returns to reuse the land.
Let’s consider the other options:
#A. Modern agriculture
- This involves mechanized farming, use of fertilizers, irrigation, and pesticides, not allowing land to stay idle for years.
#B. Strip cropping
- This is planting alternate strips of different crops to reduce erosion, not about leaving land unused.
#C. Contour ridging
- This is a soil conservation method involving making ridges across slopes, not fallowing.
#D. Crop rotation
- Involves rotating different crops on the same piece of land, not leaving it fallow.
Summary:
Leaving land uncultivated for several years to naturally regain fertility is known as the bush fallow system.
