Re: Opinion: What are the challenges of Terra Preta
I think one of the serious challenges of terra preta will be to fully understand the changes in soil ecosystems and microbiology that result with the addition of biochar, and how these may impact plant growth for a wide variety of species. For example, from what I've read and others here have discussed, it seems that terra preta has a high retention of nitrogen, which encourages the growth of leafy plants but it may not benefit the growth of fruit-bearing or root-vegetable plants.
