Session 3. High output and high (eco)efficiency
Title Abstract Author Other files

Trace elements supply and requirements in Dutch dairy farming

Well-supplied trace elements are necessary for production and animal health. The Water Framework Directive requires a reduction of the output of heavy metals.

No trade-off between root biomass and aboveground production in Lolium perenne

Grasses have dense rooting systems, but nutrient uptake and drought resistance can be increased, and N-leaching reduced, if rooting is further improved.

The use of radar images for detecting when grass is harvested and thereby improve grassland yield estimates

Cutting date and frequency are important parameters which, together with weather, soil conditions, botanical composition and fertilizer, determine grassland yields.

Farm-specific development plan: a tool to manage and improve individual dairy farms

Pilot farm networks are very efficient in developing and implementing innovative measures and strategies to improve farm performances. At farm level, their specificities must be considered.
