Reintroducing native grasses to hold moisture Rotational grazing, no-till, cover crops, and native grasses mean an improvement in plant growth, moisture retention, and erosion control on the Anderson ranch. By 5/5/2021 After enduring dusty, dry years on their Lemmon, South Dakota, ranch back in the early 2000s, Chuck and Koreen Anderson realized one important thing. They needed to keep moisture on the place. Their sandy, loamy soils were parched and dry. With the Andersons’ implementation of rotational grazing, no-till practices on their crop ground, using cover crops and a rigorous reintroduction of native grasses, they immediately saw an improvement in plant growth, moisture retention, and erosion control.
