Abstract

The cycling of N in grassland involves a large number of different transformations, some of them mediated enzymically by soil micro-organisms, others by plants or by grazing animals, and some resulting from physico- chemical reactions in the soil and atmosphere. The relative importance of the transformations varies widely with the type of grassland and its management, and with soil and climatic factors. It is important to bring together and to integrate the information now available on these topics so that the impact of changes in management and weather can be predicted more effectively. The objective of this project is to synthesize and review information on N cycling and losses from other components of PU 01, 02, 35, 57 and 58, develop conceptual and mathematical descriptions of the processes involved and integrate information over large spatial and temporal scales. This, in turn is used to supplement and underpin strategic research conducted for MAFF.
