Recommended Grazing Management Practices for Sainfoin Pastures

Definition: Sainfoin (Onobrychis viciifolia) is a perennial legume that is commonly used as a forage crop in livestock production systems. It is known for its high nutritional value and ability to fix nitrogen in the soil, making it an excellent choice for sustainable grazing management.

1. Establishment and Maintenance

Sainfoin pastures should be established on well-drained soils with a pH range of 6.0 to 7.5. Prior to sowing, the land should be properly prepared by removing weeds and ensuring adequate soil fertility. Sainfoin can be sown either alone or in a mixture with grasses, depending on the desired forage composition.

Regular maintenance practices, such as mowing and fertilization, are essential for the long-term productivity of sainfoin pastures. Mowing should be done before the plants reach the flowering stage to prevent seed production and maintain high forage quality. Fertilization should be based on soil test results and should aim to provide adequate levels of essential nutrients for optimal growth.

2. Grazing Management

Grazing management plays a crucial role in maximizing the productivity and persistence of sainfoin pastures. The following practices are recommended:

Rotational Grazing:

Divide the pasture into smaller paddocks and rotate livestock between them. This allows forage plants to recover between grazing periods, resulting in improved regrowth and overall pasture health.

Stocking Rate:

Ensure that the stocking rate is appropriate for the sainfoin pasture’s carrying capacity. Overgrazing should be avoided, as it can lead to reduced plant vigor and decreased forage production. Regular monitoring of forage availability and livestock performance is essential for adjusting stocking rates accordingly.

Grazing Height:

Set a minimum grazing height to prevent excessive defoliation and promote regrowth. Leaving a residual stubble height of 4 to 6 inches helps protect the crown of the sainfoin plants and ensures their ability to regrow rapidly.

Rest Periods:

Allow for an adequate rest period between grazing cycles to allow sainfoin plants to recover and replenish their energy reserves. The duration of the rest period will depend on factors such as weather conditions, growth rate, and plant vigor.

3. Weed Control

Weed control is essential to maintain the productivity and quality of sainfoin pastures. Regular scouting and timely intervention are crucial to prevent weed competition. Integrated weed management practices, including cultural, mechanical, and chemical control methods, should be employed to effectively manage weed populations while minimizing environmental impact.
