“…The model then uses the CN to determine runoff for each event in the dataset and sums runoff for all events to determine total annual runoff. We tested this runoff prediction approach using data from 12 studies that were independent of those used to develop the runoff model (Bond, 2010;Busch et al, 2013;Coote and Hore, 1979;Cramer et al, 1976;Edwards et al, 1983;Edwards et al, 1972;Komor and Hansen, 2003;Madden and Dornbush, 1971;Miller et al, 2004;Powers et al, 2010;Uusi-Kamppa et al, 2007;Westerman and Overcash, 1980). The studies represented 37 site years and reported lot characteristics, annual precipitation, and annual runoff.…”

“…On earthen lots, both manure and soil are sources of solids P loss, and the P content of eroded solids is generally less than the P content of manure. For example, Cramer et al (1976) measured the P content of eroded solids in settling basins draining paved and earthen cattle lots in Wisconsin. They found that the solids P content from the paved lot was 2.4 times greater than the solids P content from the earthen lot.…”

Phosphorus (P) loss from agriculture can compromise the quality of receiving water bodies. For cattle farms, P can be lost from cropland, pastures, and outdoor animal lots. We developed a new model that predicts annual runoff, total solids loss, and total and dissolved P loss from cattle lots. The model requires input for annual precipitation, lot surface type, soil test P for earthen lots, cattle number and type, frequency of cleaning, and percent vegetative cover. The model estimates annual runoff using a precipitation dataset and curve number, annual solids loss based on annual runoff, annual particulate P loss based on solid loss and manure and soil P content, and annual dissolved P loss for each runoff event. Testing showed that the model reliably estimated runoff, solids loss, and P loss from a wide variety of lots and was more accurate than other, currently used models. The new model provides a valuable tool for developing whole-farm estimates of P loss and more effectively targeting P loss mitigation practices.
