<br />Cropland C values will be taken from Table 15. Select the appro- <br />priate charts, then select the correct cropping sequence for the given <br />field. It will be necessary to exercise good judgment when selecting C <br />values. All crops are not listed, because many are similar. There would <br />be no appreciable difference between wheat and barley. Also, there <br />would be no appreciable difference between corn harvested as silage and <br />sorghum; planted in rows, harvested as bundles. <br />P (erosion control Practices) factors are support practices which slow <br />runoff water and thus reduce the amount of soil it can carry. The P factor <br />is the ratio of soil loss with the supporting practice to that of soil loss <br />with up-and-down-hill culture. <br />Read the appropriate P value from Table 16. <br />0
