Development of a model of growth of grass/white clover swards for a grassland management support system
A decision support system for management of grass/white clover swards is being developed in Northern Ireland,to help organic dairy farmers to budget their forage during the grazing season.A model developed to predict growth and clover content in monitor plots was tested against data from plots throughout the Province in 2006 (Laidlaw et al.,2007).While the output of the model reflected differences in herbage growth and clover content between sites,soil mineral nitrogen availability as an input needed to be varied throughout the season and was site dependent.Also white clover content was considerably lower in grazed paddocks than in plots laid down on these paddocks and protected from grazing cows.These issues are addressed in this study.
