Joe Paul wrote:Hi all, we currently have a pasture already sown with seeds for sheep/cattle (plantains and rye grasses) and are grazing sheep, cattle, pigs, and geese on this successfully. We wanted to explore the possibility of adding a lot more diversity to the pasture to make it more sustainable and offer a wider range of grazing for all these animals - how does one go about doing that? Do you just sow over-top and hope the additional seeds will take root? Is there a certain list of seeds one should consider when starting to make such a transition?
