The research I’ve been doing on bio char is on how it’s made and that it needs to be pre charged before using. There’s a big difference between charcoal and biochar.
Hi to you all I like the experiment but honestly thought the bio chard would of done far better , but some tasty spuds you have got nathen had me worried with the knife that was for sure , so nice to see you lovely family helping you harvest . Stay safe all best Bill and Val
Their biochar is way too coarse = poor quality, plus afaik even after charging the biochar needs to sit a few years in the soil because when normal people charge it they typically do a poor job.
