Re:The U.S. corn belt has lost a third of its topsoil by tastyfreeze on Thursday April 15, 2021 @04:51PM (#26825962)
You should be worried about soil. Increasing the soil organic matter improves its water holding capacity, improves tilth and increases infiltration rate. In turn that decreases how much water is needed for crops in dry times and allows recharging of aquifers.

With the currently degraded soil, farmers worry about a couple inches of rain causing washouts or flash floods. Water runs over the top of the soil into surface waterways. Healthy soil can infiltrate many inches of rain an hour.
