Summary of Methods: 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.

Annotation: From 1967 through 1980, moderate stocking rates averaged 15 ha/AU. From 1981 through 1985, 2 range units were grazed continually from 1 March to 15 November and deferred from 16 November to 28 February, and the third RU was continuously grazed yearlong. The yearlong continuously grazed RU was stocked at 13 AU/ha, and the seasonally grazed RU's were stocked at 15 and 19 AU/ha. Study sites were sampled in June and August/September of 1982-1984, and for a final time in September 1985.
