摘要

This paper draws on a larger survey of recent and current soil fertility research in the New Zealand high country to examine, briefly, three themes in nutrient cycling. The role of nutrient accessions to open systems is recognized for improved range. Current long-term revegetation studies show the need to take account of income from rock weathering. The importance of understanding the role of different plant species, soil amendments and pastoral practices in activating or impeding nutrient cyclingproper is indicated from recent studies involving monitoring of exchangeable aluminium, comparing lupins with other legumes and studying the effects of planted conifers on the mineralization of grassland organic matter. The dimensions and magnitudes of grazing-induced nutrient transfers are outlined in relation to their risks of loss from periodic hydrologic events, as well as recognizing the roles of pasture improvement and grazing management in accelerating nutrient cycling.
