What is a common issue with relying solely on legumes in livestock forage?

Relying solely on legumes in livestock forage can lead to issues primarily due to the specific soil conditions they require. Legumes, such as clover and alfalfa, often thrive in well-drained, moderately fertile soils with a specific pH range. If the soil conditions do not meet their needs, such as being overly acidic or having poor drainage, the growth and yield of legumes can be significantly hindered. This reliance can result in a forage system that is not sustainable or productive in the long-term if the desired soil conditions cannot be consistently met.

While other factors like cost, palatability, or protein content are important in the overall management of livestock forage, the specific soil requirements for legumes present a critical challenge in their exclusive use. Ensuring that the grazing system has adequate soil conditions for legumes is essential for optimizing forage production and livestock health.
