About this project
PRACTICAL SECTION FOR FARMERS AND GROWERS
Why do we need models? A significant barrier to more efficient use of nitrogen fertiliser by arable farmers and horticultural growers is the lack of information on seasonal, soil-related and cultural variations in the supply of mineral nitrogen by the soil and the requirements for nutrients by the crop.
Researchers have identified many processes of nitrogen transformation and the controls exerted by climate and soil conditions. Models provide a tool for making practical use of this huge body of information and could be of enormous value in providing fertiliser recommendations and planning crop rotations on working farms.
