Can grazing species be used to manipulate the amount of nitrogen leaching to groundwater?

摘要：

Introduction Regulatory limits on nitrogen (N) leaching from farmed land in the Lake Taupo catchment in New Zealand make the identification of effective N leaching mitigation strategies for land owners imperative.More N has been shown to leach from cattle than from sheep urine patches due to the greater volume of urine as well as the greater rate of N deposited in cattle urine patches (Williams and Haynes,1994).A field-scale study was undertaken to examine the potential for using different grazing species to reduce the amount of N leaching from grazed land.
