This report begins with an ‘Executive summary’ which highlights key findings of the research undertaken.  The body of the report is then presented in five distinct sections.  Section 1 describes the dairy cow production study undertaken and examines the performance of the cows on each of the four experimental systems.  Section 2 provides a detailed description of the establishment and management of the experimental ‘farmlet’ site used to measure nutrients losses.  In Sections 3 and 4, details of nutrient losses measured within the farmlet site are presented.  Finally, Section 5 provides a detailed description of four plot experiments which were undertaken to examine strategies by which to reduce phosphorus losses from applied slurry.

The objective of this review is to establish the potential and accuracy of the grass measurement methodologies that are currently applicable to Northern Ireland, with a particular focus on the relationship between compressed sward height and herbage mass, and to identify strategies that could be used to improve accuracy and adoption of grassland measurement technologies.
