A farmer planted kales in his farm in a sunken seed bed. Why did the farmer use the sunken seed beds?
The farmer likely used sunken seed beds for a few reasons:
1) Moisture retention: Sunken seed beds allow for better moisture retention in the soil. When the beds are sunken, they can collect and hold rainwater or irrigation water, preventing excessive evaporation and ensuring a consistent water supply for the plants.
2) Protection from wind: Sunken seed beds offer some protection from strong winds. By being lower than the surrounding soil, the plants in the sunken seed beds are shielded from gusts that can potentially damage or uproot them.
3) Improved drainage: Sunken seed beds can help improve drainage in areas with heavy rainfall or soil that retains water. The depression in the ground allows excess water to drain away more efficiently, preventing waterlogging and the risk of root rot.
4) Easier weed control: By sunken the seed beds, the farmer may have made it easier to control weeds. The depression offers a defined space for the desired plants, making it more efficient to remove and manage any unwanted weeds that may compete with the kales for nutrients, sunlight, and space.
Overall, using sunken seed beds can provide benefits for moisture retention, wind protection, drainage, and weed control, which can contribute to healthier plant growth and better yields for the farmer.
