- In the semi arid Plains ofa particular region farmers grow wheat in some long and leave back the black strips of land but take care of that land by using weedicides this is because rain harvesting is done in that black stripped areas.
- Sometimes semi arid areas do not get enough amount of rainwater due to some environmental conditions and hence the prestored rainwater in the black strips are used to cultivate wheat crops.

Explanation:
The farmers in this region manage soils by creating alternating yellow and black stripes on the ground. The yellow stripes consist of land covered by ripening wheat, while the black stripes are bare soil on which no crop is grown. Farmers use herbicides or tillage to remove any weeds that try to grow in the black stripes. This management practice serves multiple purposes.
Conservation of Soil:
One reason why farmers manage soils in this way is to minimize erosion and soil degradation. By leaving half of their land as bare soil, farmers allow the soil to rest and recover. This reduces the risk of erosion caused by wind or water, as well as the loss of nutrients from the soil. It also helps to prevent soil compaction, which can impede the growth of crops. Resting the soil in this manner is an effective strategy to conserve soil quality and fertility.
Water Conservation:
Another reason for this soil management practice is to conserve water. By leaving the black stripes bare, farmers create areas where rainwater can infiltrate the soil and be stored. These bare stripes act as reservoirs, allowing water to percolate into the soil and be retained for future use. This stored water can then supplement the rain on the wheat crop planted in the yellow stripes the following year. By maximizing water availability, farmers can ensure better crop growth and yield.
Transpiration Management:
Additionally, the bare soil in the black stripes helps to manage transpiration in the wheat plantation. Transpiration is the process by which plants lose water through their leaves. By allowing free evaporation from the soil of the bare stripes, farmers can reduce the overall transpiration rate in the wheat plantation. This helps to conserve water and ensure that the wheat plants receive adequate moisture for growth and development.
In summary, farmers in this region manage soils by creating alternating yellow and black stripes on the ground. This practice helps to conserve soil, store rainwater, and manage transpiration in the wheat plantation. By adopting these soil management techniques, farmers can enhance the sustainability and productivity of their agricultural practices.
