anyways all beds with biochar are doing better hands down. char holds A LOT of water.
That is a very interesting video, I just finished watching it. I am visiting family in Kentucky for the next week, but I can't wait to get back to New York and start building my beds. I think I have my strategy down!
Have you googled the video, "Secrets of El Dorado"?
Biochar is just another piece of the puzzle that nature has laid out through evolution.
Think of your Hugelkulture as mimicking what happens in nature. Fire is just another part of the process.
Scientists in the video seem to think that the biochar absorbs nutruinces from decaying organic materials; will hold the compounds as a reservoir until the plants can get their roots down into it. They theorize that once biochar has been charged with fertilizer the reservoirs can last up to 40 years, before it needs to be charged again. In the video, the German scientist’s yearly experiments seem convincing, but to my eye pale in comparison to what is going on in the hugelkulture berms.
The only way to tell for sure is to make two berms, one with biochar and one without and report back to us in a couple years your results.
Oh yes, I personally believe the biochar berms were part a pit fire ceramic industry and the remaining pot fragments were pots that exploded during the firing. So I wouldn’t start throw broken pots and rocks into your berm, just because that’s what the scientists are finding. But then again that calls for another experiment; do I see any raised hands for volunteers?
