How to Increase Grass Content in Legume-Heavy Field

When we first started, this field was at 60-70% legumes (alfalfa/clover) down to 60-70% grasses. We wanted to moved this percentage because grass is the carb/sugar which will help with weight gain, and too many legumes can lead to bloat. We put down 25-50 lbs of perennial rye/orchard grass mix. Also grazing hard right before a killing frost - this will allow the grass next year to move ahead of the legumes.
We lost our first, lead ewe, Susan.
