I was very impressed by those Nordic studies where they showed that a directly mixed diversity of vegetation led to rapid formation of topsoil. It is hard to have mixed crops veggie crops, but it seems a perfect solution for grazing fields. Just plant a mix of suitable plants like my lettuce mesclun patch, no not Mescalin, you druggies.
Then just let the herds loose to provide poop compost. I see rotation of such mixed flora fields with monocultures after soil regeneration, as the long term solution.
