Proposed Changes to Section 4 of the Iowa State Technical Guide
It has been determined by the NRCS State Conservationist for Iowa that changes must be made in the NRCS State Technical Guide specifically in practice standards #327, Conservation Cover; #330, Contour Farming; #332, Contour Buffer Strips; #412, Grassed Waterway; #585, Stripcropping, Contour; and #638, Water and Sediment Control Basin, to account for improved technology. This practice can be used in systems that treat highly erodible land.
