Sustainable Intensification Of Livestock Systems Using Forage Legumes In The Anthropocene, José C. B. Dubeux Jr., D. M. Jaramillo, E. R. S. Santos, L. Garcia, L. M. D. Queiroz, K. R. Trumpp
IGC Proceedings (1997-2023)
Sustainable intensification of livestock systems implies greater efficiency in resource utilization resulting in greater output of products and other ecosystem services per unit of resource input. Strategies to improve resource use efficiency include diversification of plant and ruminant species with complementary resource use. Forages that have root systems with contrasting architecture and exploring different soil layers with complementary use of resource acquisition (e.g., nutrients, water) could enhance primary productivity. Belowground interactions with soil microbiota (e.g., mycorrhizae) is key to enhance resource utilization. Forages with complementary canopy characteristics that helps enhancing light interception and utilization could also lead to greater resource …

Vegetation Dynamics Of Campos Under Grazing/Fire Regimes In Southern Brazil, Fernando L. F. De Quadros, J. P. P. Trinidade, D. G. Bandinelli, L. Pötter
IGC Proceedings (1997-2023)
Natural grassland vegetation in Southern Brazil, known as campos, has most likely evolved under a disturbance regime that included fire and grazing (Pillar et al., 1997). Nowadays, the composition of the vegetation of campos is grazing- and fire-dependent (Boldrini et al., 1997). Its importance can be evaluated by the fact that it represents 37 % of the state’s area and provides 77 % of the slaughtered cattle at Rio Grande do Sul (Barcellos et al., 2002). The objective of this experiment was to evaluate the vegetation dynamics of campos under grazing/fire regimes in order to explore the …
