A fact sheet from Profile Products explains soil loss, cover (C) factor, and percent effectiveness (PE) with formulas, criteria, and guidance on erosion control product selection. Text and a green-bordered box are present.

Prevention of soil loss is the first priority for erosion control products. Establishing vegetation as quickly as possible for long-term erosion control is the second priority. Since different products prevent soil loss to varying degrees, matching the right product to a given situation requires that you understand how to calculate potential soil loss—and then determine the degree of protection required to prevent the loss. The information in the sheet below is intended to help you understand those calculations when quantifying slope erosion potential.
