' NONTECHNICAL SOI L5 DES CRI PTI~PORT • <br />1972 Broadway <br />~ Soil name and description <br />Sol <br />125 ~ Unnamed fine sandy loam, 3 to 12 percent elopee <br />' ~ The unnamed 125 Boll consists of very deep, well <br />~ drained eoile on terraces. These eoile formed in <br />~ alluvial materials Erom sandstone. The surface layer <br />ie fine sandy loam about 5 inches thick. The sub BOil <br />ie loam 15 inches thick. The upper 10 inches of the <br />substratum ie sandy loam. The lower eubet ratum Go a <br />depth of 60 inches or more ie loamy sand. Permeability <br />~ ie moderately rapid. Available water capacity Se <br />moderate. AunoEf ie medium to rapid, and the hazard of <br />water erosion ie high. <br />B~ ~ Unnamed silty clay loam, 0 to 2 percent elopee <br />~ This unit ie suited Eor irrigated crops. The main <br />' ~ limitation ie sandy underlying material. Deep cute can <br />expoee Bandy material which will cause prob lame with <br />~ furrow irrigation. Furrow and sprinkler irrigation is <br />suited to [hls soil. Irrigation water needs to be <br />' ~ applied at a rate that ins urea optimum production <br />without Snc rearing deep percolation, runoff, and <br />~ erosion. Due to the rapid permeability of these soils. <br />' ~ over irrigation resulting in an increase in deep <br />~ percolation could increase the potential for leaching <br />~ fertilizer and peat is ids into the groundwater. TilGh <br />~ and fertility can be improved by returning crop residue <br />' ~ to [he soil and using a suitable rotation. <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br /> <br />
