Soil & Carbon

Sustainable Agriculture projects:

Improved cultivation practices in developing countries, exploration of sustainable agricultural practices such as reduced tillage, cover crops, and intercropping on soil quality measures (e.g., nutrient status, organic matter content, and water stable aggregate formation).


No-tillage management of crops for biofuel production, rattoon cropping, which is essentially “cutting the grass” and vegetative re-development of the biomass, eliminates the need for conventional agricultural practices and preserves the soil resource.


Soil amendment with biochar as part of a sustainable agriculture production system, identifying the practical benefits of biochar production and application as a soil amendment for waste stream management, soil fertility, and C sequestration.


Effect of elevated atmospheric CO2 concentrations on root crop production and nutrition.  Rise in atmospheric concentrations of CO2 may result in increased biomass production in root crops, which are staple foods in many developing countries, however whether the nutritional content will also shift in response to elevated CO2 is unknown.
