Brazil has over 80 million ha of tropical pastures formed with species of Brachiaria (syn. Urochloa), mostly grazed by beef cattle and with low fertilizer inputs, especially nitrogen. Recent investigations by our team show that stoloniferous legumes such as forage peanut (Arachis pintoi) and Desmodium ovalifolium are able to persist in mixed swards with Brachiaria brizantha (cv. Marandu) if grazing height is regulated (maximum 30 cm) so that radiation can reach the soil surface allowing stolons to take root. These legumes can persist in mixed pastures and produce milk or animal weight gains similar to the application …

Ecosystem Benefits Of Invasive Annual Grass Removal, S. L. Clark
IGC Proceedings (1977-2023)
Invasive winter annual grasses (IAGs) are altering rangeland ecosystems across millions of hectares in the western US. These winter annuals outcompete native plants for soil moisture and nutrients, leading to devastating impacts on ecosystem functions. The IAG seedbank is short-lived and often does not persist beyond 3 years. Past tools for IAG control have only provided short-term control or caused injury to the native plant community, making it difficult for researchers to assess the ecosystem benefits of IAG removal. A newer herbicide option, indaziflam, provides IAG control for three or more years. Indaziflam’s extended soil residual control and tolerance of …

IGC Proceedings (1977-2023)
The terms grasslands and rangelands are often confused, but the terms used to describe the people who live and manage these areas are even more confusing. The myriad of words used about these people includes: pastoralists, farmers, ranchers, herders, transhumants, indigenous peoples, nomads, graziers, gauchos. The terms used vary across the world, and meanings vary across time and space. One definition of pastoralists is “livestock-keepers who specialise in taking advantage of variability, managing grazing itineraries at a variety of scales so that livestock feed better than without a herder” (Krätli 2019). The United Nations Decade of Family Farming defines farmers …
