I might add that, while Dave and I provided hundreds of footnotes to our sources in Edible Forest Gardens, the dynamic accumulator section is one that needs an overhaul. Most of our data came from Kourick who is about to release an update to his research. In fact I don’t really teach dynamic accumulators in my courses any more at all, until we get some more data. Several folks in academia are looking at the topic here in the states.
Do they still argue after that?
John Lewis Morgan wrote:Some people are really zealous about goat care. Yes. They will argue with anybody about anything goat-related that is different from how they do it. "if you don't remove all toxic plants from your goats you are a murderer" - type attitude.
I had a feeling! I try not to argue with people who discount reality...
Lukas Eriksson wrote:Thanks for the good answers! I have a few more question I hope someone could answer for me. If I would let my goats eat a diet mostly from bushes and trees, would that minimize the need for extra minerals? When I see pictures of goat pastures it´s often just grass and that makes me think that it´s a very unnatural place for goats and maybe that is why they like escaping so much? Maybe not, but it´s a thought.
Would seaweed give goats some of the minerals they need? If I would make hay for goats should it be from more deep rooted plants like alfalfa instead of grass?
Peter Ellis wrote:If your soil does not have healthy soil biology, then it will not matter what mineral supplements you put on or in the soil, they will not be plant available. If the soil biology is healthy, you won't need supplements to mineralize the soil, and you probably won't need them for your animals either, because they will be getting what they need from their food.
Peter Ellis wrote:That theme that some soils don't have certain minerals gets quite a bit of play. You might want to look into what Dr. Ingham has to say on the subject.
