The Ossekampen Long Term Grassland Experiment; yield responses to temperature and precipitation surplus
The Ossekampen Long Term Grassland Experiment was established in 1958 and consists of eight fertilizer treatments. Since its establishment the management has remained unchanged, with two cuts per year. We used the Ossekampen experiment dataset to assess the effects of temperature and precipitation surplus on annual yields and botanical composition. Yield data of the complete sward were available for all 63 years, while data of the functional groups were available for 40 years. Using a linear mixed model, we found that the dry matter (DM) yield increased with increasing temperature and increasing precipitation surplus. We found that grasses and herbs responded differently to temperature and precipitation surplus. Temperature did not affect the grasses, but only affected the herbs. Also, the yields of the herbs were less affected by drought than those of the grasses.
