Vellinga, Th.V.
The general objective of the research prsented in this thesis was to gain insight into the effects of various management decisions at operational, tactical and strategic levels on herbage DM yield and N content per cut, N losses via leaching and N2O and CO2 emissions, using multi-site and many-years experiments, statistical analyses and empirical models. New criteria for environmentally sound N recommendations and tools for operational grassland management were derived, so as to improve the decision making in grassland management on intensive dairy farms
