Birdsfoot trefoil
Established stand management
Special considerations
If properly harvested and stored, birdsfoot trefoil silage can provide a high-quality forage with fewer risks of damage due to weather. For high-quality silage, field wilt to a moisture content of 60 to 70 percent before ensiling for conventional upright, bunk, or pit silos; field wilt to a moisture content of 40 to 60 percent for sealed upright silos. Making a good, tight pack ensures an oxygen-free environment and depends much on fineness of chop, moisture content, and rate of fill. Silage preservatives, additives, and inoculants may improve silage fermentation in some cases, but are not a substitute for proper management.
Used at recommended rates and properly applied, organic acid preservatives make it possible to successfully store birdsfoot trefoil hay when baled at up to 25 percent moisture.
