Fertile dark soils made by humans in the Amazon basin, terra preta, have influenced the manufacture of the biochar based fertilizers. Different types of biochar exist but not all of them are good in improving the quality of the soil. FTIR was used to distinguish between the more and the less fertile biochar.

Agricultural soils are the primary anthropogenic source of atmospheric nitrous oxide (N2OO), contributing to global warming and depletion of stratospheric ozone. Biochar addition has shown potential to lower soil N2OO emission, with the mechanisms remaining unclear. We incubated eucalypt biochar (550 °C) - 0, 1 and 5% (w/w) in Ferralsol at 3 water regimes (12, 39 and 54% WFPS) - in a soil column, following gamma irradiation. After N2OO was injected at the base of the soil column, in the 0% biochar control 100% of expected injected N2OO was released into headspace, declining to 67% in the 5% amendment. In …
