What it calculates
The “Soil Erosion” calculator computes Erosion, t/ha/yr in t/ha from 6 parameters: rainfall erosivity r (MJ·mm/(ha·h·yr)), soil erodibility k (t·ha·h/(ha·MJ·mm)), slope length (m), slope (%), cover-management factor c (0–1), support practice factor p (0–1).
Estimates environmental impact and carbon footprint.
Example calculation
With parameters Rainfall erosivity R = 1,000 MJ·mm/(ha·h·yr), Soil erodibility K = 0.03 t·ha·h/(ha·MJ·mm), Slope length = 50 m, Slope = 8 %, Cover-management factor C (0–1) = 0.2, Support practice factor P (0–1) = 1 the result is 7.62 t/ha (USLE model, mean annual soil loss).
How to use
