Effectiveness of these methods ranges from 80 to 99 percent, <br />depending upon method and rate of application. (C) factors range from <br />0.2 to 0.01. The application rate and estimated coverage of the soil <br />resulting from that rate should be compared with the coverage of other <br />mulch application rates to determine the value of (C) in the specific case. <br />*Percent soil loss reduction as compared with fallow ground. <br />• Source: Soil Conservation Service <br />-85-
