Designing High-Yielding, High-Diversity And Low-Input Temporary Grasslands, Karen Søegaard, Tine B. Mortensen, Jørgen Eriksen

IGC Proceedings (1997-2023)

Species-rich swards have received increasing interest due to their focus on ecosystem services, animal welfare and product quality. However, in high-yielding swards the proportion of herbs is often limited and there is little knowledge of their management. Seed mixture composition, cutting frequency, fertilization and grazing/cutting strategies were examined over 4 years in 3 experiments to quantify their effects on herbage yield and botanical composition. Inclusion of herbs in the sward gave similar or higher annual yields but swards established with 100% herbs depended on the presence of a driver species. The effects of management differed between species. Herb content in …
