C (cropping - management) factors are the ratios of soil losses from lands cropped under specified <br />conditions to the corresponding losses from tilled, continuous fallow. C factors for land uses other than <br />cropland are included on Figures 7,8, and 9. The percent ground cover is the primary item to consider <br />because a slight change in the percent ground cover will result in a significant change in the erosion <br />prediction. <br />Figure 7 - "C" Factors for Permanent Pasture and Rangeland <br />ADJACENT AREA - "C" FACTOR <br />Greasewood Reference Area <br />No appreciable canopy. Canopy is assumed to be the cover contributed by trees and shrubs. Based on the <br />2010 Vegetation Evaluation the combined tree and shrub cover totals 11.25%. The percent ground cover for <br />the reference area shown above is 50.1 %. Use figure 7 identified above and interpolate to determine the C <br />factor for 50.1 % cover. <br />CANOPY NO APPRECIABLE CANOPY <br />PERCENT GROUND COVER <br />40.0% 50.1% 60.0% <br />No G 0.100 0.071 0.042 <br />appreciable dacent "C" Factor 0.071 <br />canopy <br />Shadscale Reference Area <br />No appreciable canopy.
