Black soil is known for its ability to hold moisture. This soil can retain moisture for a long time, which can help crops during dry seasons. Black soil is sticky when wet, so it’s difficult to work with. It’s usually tilled after the first shower or during the pre-monsoon period.
The ability of soil to retain water is related to the size of its particles. Clay soil has small, fine particles, so it retains the most water. Sand has larger particles and retains the least water. Silt and loam have medium-size particles and retain a moderate amount of water.
