| http://www.w3.org/ns/prov#value | - We are currently adapting SurPhos to simulate grazing and validating the model with field data from Australia & England & small-plot, simulated grazing data from several locations in the U.S. We will use producer information & data to simulate P loss from areas where cows spend time outside, including pasture, over-wintering areas, & barnyards.
