Renforth, P.; et al. (2015): The dissolution of olivine added to soil: Implications for enhanced weathering

Renforth, P.; Pogge von Strandmann, P.A.E.; Henderson, G. M. (2015): The dissolution of olivine added to soil: Implications for enhanced weathering. In Applied Geochemistry 61, pp. 109–118. DOI 10.1016/j.apgeochem.2015.05.016.

"Here we present results from laboratory flow-through dissolution experiments which seek to bridge this observational discrepancy by using columns of soil returned to the laboratory from a field site. We constrain the dissolution rate of olivine added to the top of one of these columns, while maintaining much of the complexity inherent in the soil environment."

Viger, Maud; et al. (2014): More plant growth but less plant defence? First global gene expression data for plants grown in soil amended with biochar

Viger, Maud; Hancock, Robert D.; Miglietta, Franco; Taylor, Gail (2014): More plant growth but less plant defence? First global gene expression data for plants grown in soil amended with biochar. In GCB Bioenergy, pp. n/a. DOI 10.1111/gcbb.12182.

Paper on biochar risks. "Using the model plant Arabidopsis and the crop plant lettuce (Lactuca sativa L.), we found increased plant growth in both species following biochar application. Statistically significant increases for Arabidopsis in leaf area (130%), rosette diameter (61%) and root length (100%) were observed with similar findings in lettuce, where biochar application also increased leaf cell expansion."
