Why is flooding good for agriculture?
Floods cause disasters, but they can also be beneficial. Whenever a river overflows its banks, it dumps sand, silt and debris that it has carried downstream onto the surrounding land. After the flood waters move away, the soil is more fertile, because of the organic matter and minerals in this material.
What is agricultural flooding?
Flood washes away the topsoil which is the richest part of the soil and contains organic matter and other crop nutrients and deposits elsewhere. This eventually leads to a reduction in the soil’s fertility and its sustainable use.

How much sediment is deposited on topsoil?
Moving water carries soil particles. When the water slows, sediment is deposited on the soil surface, ranging from a few inches to 15 feet of sediment covering topsoil – or more. Shallow deposits of 2 inches or less can be tilled into the topsoil with normal tillage equipment.
Why do farmers need to till deep enough to thoroughly mix this sediment with the topsoil?
Farmers need to till deep enough to thoroughly mix this sediment with the topsoil.
