Biofuelwatch (2020): What have we learned about biochar since 2011? Update by Rachel Smolker, January 2020.
"What we have concluded from that review is that 1 ) there has been a massive proliferation of studies of biochar over the past several years reflecting a greatly expanded interest and an influx of funding to soil science researchers. 2) There has been a widening of the scope of proclaimed “uses” for biochar – no longer just for carbon sequestration, but now for many other applications including increasing water retention in soils, improving nutrient uptake in agriculture, reducing fertilizer use and reducing emissions from fertilizer applications, use as feed for cattle to reduce methane emissions, and more."
