grazing management effects on sediment, phosphorus, and pathogen loading of streams in cool-season grass pastures. | erosion and runoff from pastures may lead to degradation of surface water. a 2-yr grazing study was conducted to quantify the effects of grazing management on sediment, phosphorus (p), and pathogen loading of streams in cool-season grass pastures. six adjoining 12.1-ha pastures bisected by a stream in central iowa were divided into three treatments: continuous stocking with unrestricted stream access (csu), continuous stocking with restricted stream access (csr), and rotational stocking (rs). ra ... | 2011 | 21712600 |
