j SJ.BR 4/85 <br />$IO1This unit is well suited to irrigated row, field, and orchard crops. It <br />has few limitations. Furrow, border, corrugation, and sprinkler irrigation <br />systems are suited to this soil. Water should be applied in amounts suffi- <br />cient to wet the root zone but in amounts small enough to minimize the <br />leaching of plant nutrients. A cropping system that includes crop rotation or <br />a cover crop, use of crop residue and proper tillage improves soil tilth and <br />increases fertility and water infiltration. If this unit is used for dryland <br />grain crops, the main limitation is low rainfall during the growing season. <br />Because precipitation is not sufficient for annual cropping, a cropping system <br />that includes small grain and summer fallow is most suitable. Crops respond <br />to nitrogen and phosphorus fertilizer. <br />$IOlIf this unit is used for homesite development, the main limitations are <br />moderately slow permeability, low strength, and moderate shrink -swell capa- <br />city. If the soil is used for septic tank absorption fields, the limitation <br />of moderately slow permeability can be overcome by increasing the size of the <br />absorption field. If the density of housing is moderate to high, community <br />sewage systems are needed to prevent contamination of water supplies as a <br />result of seepage from on-site sewage disposal systems. Buildings and roads <br />should be designed to offset the limited ability of the soil in this unit to <br />support a load. If buildings are constructed on this soil, properly designing <br />foundations and footings and diverting runoff away from buildings help to <br />prevent structural damage because of shrinking and swelling. <br />1)RLLIN1INANZY <br />SUBJECT TO la"iVISION <br />
