It estimates how much soil will be lost to erosion for each field on a farm.
In making its estimates, it includes information collected from satellites.
It also makes calculations based on cropping alternatives, meaning a farmer can run simulations to determine how to reduce erosion.
Coming soon will be calculations about how much phosphorous is lost to erosion. That dove-tails with concerns that phosphorous runoff prompts fish-killing algae blooms in the Great Lakes, and especially in shallow Lake Erie.
