 A selective process is affecting the soil erosion of phosphorus. Smaller and lighter particles are eroded easier than larger ones. The tiny particles contain more P per unit weight than the average particle of the soil. Therefore an enrichment factor (//​enrichment//​) is used. A selective process is affecting the soil erosion of phosphorus. Smaller and lighter particles are eroded easier than larger ones.
