<br />Non-Technical Descriptions <br /> <br />Soil Survey Area: 691 GRAND JUNCTION AREA, COLORADO <br /> <br />Map unit: Ave Avalon loam, 5 to 25 percent slopes <br /> <br />Description Category: AGR <br /> <br />Agronomic <br /> <br />This unit is unsuited for row crops due to slope. This unit is best suited to a permanent <br />cover crop such as irrigated pastureland. Because of the slope, sprinkler or drip <br />irrigation is 11105t suitable for ttJe less sloping areas. Irrigation water needs to <br />be applied at a rate that insures optimum production without increasing deep <br />percolation, runoff, and erosion, <br />Description Category: XCS Capability Subclass <br /> <br />Capability Subclass 7C; noninigated <br /> <br />Description Category: ZCS Class Legend <br /> <br />Capability dassification is the grouping of soils to show I in a general way I their <br />suitability for most kinds of farming. It is a practical classification based on limitations of <br />the soils, the risk of damage when they are used, and the way they respond <br />to treatment. The soilS are dassified according to degree and kind of permanent <br />limitation, but without consideration of major and generally expensive landforming that <br />would change the slope, depth, or other characteristics of the soils; without consider <br />ation of possible unlikely major redamation projects, <br />Class VII - Not suited for cultivation. Very severe limitations. Suited for range, <br />woodland or wildlife uses if carefully managed. Usually cannot apply physical practioes <br />such as pitting, furrowing, seeding, etc. <br />e - Climate is the major hazard, Growing season may be very short; there is a shortage <br />of rainfall or bOth. <br />Description Category: SOl Soil <br /> <br />,his unit consists of very deep, we!! drained soils on intermediate valley terraces. <br />These soils formed in loess modified alluvium derived dominantly from mixed shale and <br />sandstone sources. The surface layer is sandy loam about 3 inches thick, The upper <br />14 inches at \he subsoll are loam, and the lower 13 inches are clay loam. The upper <br />12 inches of the substratum are day loam, and the lower part to a depth of more than <br />60 Inches is gravelly loam. Permeability of this soil is moderate. Available water <br />capacity is high. Effective rooting depth is 60 inches or more. Runoff is rapid. and the <br />hazard of water erosio" is high. <br /> <br />Thursday, May 25, 2000 <br /> <br />Page 1 of9 <br />
