Geoengineering: A Potential Biochar Application?
Could biochar potentially be used to fix nutrients to sustain and increase C Storage in thawing - decompositioning soils?
Higher temperature and decompo- sition rates can also increase nutrient availability, which often has a greater effect on plant growth than temperature (Chapin and Shaver 1996). Decomposition of soil C (in- cluding thawed permafrost C) with concomitant nutrient release could actually increase total ecosystem C storage if low C:N soil organic matter is replaced by higher C:N plant biomass (Shaver et al. 2000). http://www.aibs.org/bioscience-press-releases/resources/Schuur.pdf

Soil amendment
Biochar can be used as a soil amendment to improve yield, improve water quality, reduce soil emissions of greenhouse gases, reduce nutrient leaching, reduce soil acidity, and reduce irrigation and fertilizer requirements http://en.wikipedia.org/wiki/BiocharRelated Nitrous oxide emission reduction in temperate biochar-amended soil (2011)
