RM 2 of 3 <br />Most areas of this unit are used for irrigated cropland and orchards. <br />A few areas are used for dryland grain and homesite development. <br />If this unit is used for irrigated row, field, and orchard crops, the <br />main limitations are a perched water table and slow permeability. <br />Furrow, border, corrugation, and sprinkler irrigation systems are <br />suited to this soil. Because of the slow permeability of this soil, <br />the lenoth of runs should be adjusted to permit adequate infiltration <br />of water. The application of water should be regulated so that water <br />does not stand on the surface and damage the crops. A cropping syster <br />that includes crop rotation or a cover crop, use of crop residue and <br />proper tillage improves soil tilth and increases fertility and water <br />infiltration. If this unit is used for dryland grain crops, the main <br />limitation is low rainfall during the growing season. Because <br />precipitation is not suff c ent for annual croppino, a croppin- systerr. <br />that includes small grain and summer fallow is most suitable. Crops <br />respond to nitrogen and phosphorus fertilizer. <br />PR I:LIMTNAP.Y <br />SUBJECT. TO REVISION <br />13.3-47 <br />
