• GRAZING EFFECTS ON NUTRIENT CYCLING <br />Grazing activities have a definite effect upon the consumption <br />and redistribution of N contained in plant materials. The <br />redistribution of available V through dung and urine affects the <br />nutrient cycling process which can influence vegetation success on <br />rec'_aimed lands. Dung and urine return available N to the system <br />in a readily usable form, close the soil surface for immediate <br />uptake by plant (McNaughton et al. 1988). <br />It is generally accepted that the consumption of plant <br />materials by cattle and other ungulates removes N from the system <br />which in the short term is redistributed back to the soil. A study <br />by Dormaar et al. 11990) concluded that grazing resulted in more <br />NF?i N and N03;i in affected fields which increased with stocking <br />rate. ~etling (1988) suggested that the cycling of nutrients <br />through the herbivore pathway may maintain a pool of nutrients near <br />the soil sur~ace which would eventually be more available to <br />plants. <br /> <br />
