However, field research trials demonstrate a range of results that contrast overwhelming yield improvements in some places with neutral or even negative results in other places.  The mixture of hype and science has clouded the search for a mechanistic understanding of soil biochar additions. Appreciating the fact that biochar materials produce widely different results depending on soil, climate and type of biochar, the question remains: How does biochar work in soil?
