<br />~s' Furrow, corrugation, and sprinkler irrigation systems are suited to <br />this unit. Furrow irrigation is best suited to row crops, and corrugation <br />irrigation is best suited to alfalfa, pasture, and small grains. Sprinkler <br />irrigation is suited [o most crops; use of this method permits [he even, <br />controlled application of water, reduces runoff, and minimizes the risk of <br />erosion. Irrigation water should be applied at a rate that insures optimum <br />production without excessive runoff, deep percolation, and erosion. Furrows <br />should run across the slope. <br />Returning all crop residue to the soil and using a cropping system that <br />includes grasses, legumes, or grass-legume mixtures help [o maintain <br />fertility and filth. Grain and grasses respond [o nitrogen, and legL}mes <br />respond to phosphorus. <br />This unit i.s well suited [o nonirrigated crops. The main concerns are <br />reducing runoff and erosion, conserving moisture and maintaining <br />productivity of the soil. Practices that can be used to control erosion <br />include stubble mulch tillage, contour farming, and construction of <br />terraces, diversions, and grassed waterways. Maintaining crop residue on or <br />near [he surface increases [he water intake rate, reduces runoff and <br />erosion, and helps to maintain soil tilth and organic matter content. <br />Terraces reduce runoff and the risk of erosion, and conserve moisture. <br />Chiseling and subsoiling are effective in breaking up tillage pans and <br />improving water penetration. Tillage should be kept to a minimum. <br />Diversions and grassed waterways may be needed. They help prevent gully <br />erosion. <br />
