What Factors Control the Crude Protein Content Variation of a Basaltic “Campos” Native Grassland of South America?

Native grasslands are the main source of food for livestock in Campos region South America. These forage resources heterogeneous species composition, grazing management, and soil fertility within a context variable climate, all which factors that affect crude protein content over time space. Despite importance nutrition, there is gap knowledge how fertilisation, sward height, water availability influence these grasslands. We used data from long-term fertilisation experiment to construct structural model aiming identify influencing basaltic native grassland northern Uruguay. The revealed both increase (through improvement nitrogen green leaves) pathways by increases. This new approach (which identifies quantifies drive grasslands) could be support prediction models order improve nutrition
