Wood et al. sampled infiltration rates and runoff water quality on range units grazed by cattle under year-long continuous, seasonal continuous, or no grazing in Louisiana. There was no significant difference between the year-long continuous and seasonal continuous grazing treatments. Infiltration rate was significantly greater on the no grazing treatment in September 1985 compared to the combined average of the season-long and year-long treatments. Sediment production was significantly greater on the no grazing treatment in August 1983, September 1985, and all of the combined samples. Nitrogen concentration was significantly greater on the grazed treatments in August 1984 and all of the combined samples. Total phosphorus was not significantly different between the treatments.
