farmers add nutrients through fertilizers, there isn't much room for biochar to increase yield.
We found biochar amendment to soils in temperate regions to significantly decrease crop yield, averaging approximately −3%
Iterations are fine, we don't have to be perfect
climatic zones: ≤35th degree latitude including the tropics and subtropic (hereafter called 'tropics')

Yes the fact that they did not charge the biochar with soil life and nutrients in these temperate regions, when they were suppose to if they wanted an experiment that didn't fail, seems like it was setup for failure from the beginning.
Also it would seem that the farmers where still pouring copious amounts herbicide, fungicide, pesticide, fertilizer and plant growth hormone, onto their farms and then stated that the biochar did not help. It is no surprise that the soil life explosion was underwhelming and biochar didn't add as much fertility. They are still killing the soil life.
