The benefit of this deposition in reducing soil deterioration from erosion depends upon both the amount of deposition and terrace spacing. To determine P-factor values for terraces, field data were analyzed to derive an equation for deposition, as affected by terrace grade, that can be combined with a relationship for benefit from deposition. These values are used in conservation planning as part of the universal soil loss equation to estimate the reduction in soil loss produced by terraces. %U https://www.jswconline.org/content/jswc/38/1/48.full.pdf
