McNay Research and Demonstration Farm
Grazing management practices that allow cattle to congregate near pasture streams may result in the loss of vegetative cover and promote accumulation of manure near the streams, increasing the risk of nonpoint source pollution of the stream. The objective of this project was to evaluate the effects of stocking rate of pastures and the botanical composition of the pastures’ riparian zone on the forage sward height and the proportions of bare and manure-covered ground along the banks of pasture streams.
