Carbon Storage in an Artificial Soil [PDF]

, 2012
As we strive to find new technologies to dispose of our municipal solid waste, compost-like outputs (CLOs) are becoming more widely created. As a product of both aerobic and anaerobic digestion, they provide a potentially important carbon store and some ...

Interactions between plant-root exudates and soils in extracting humic-like substances

, 2010
Plants have evolved with roots in close contact with the solid phase of the soil therefore organic acid root exudates, in plant–root–microbial interactions, have attracted much interest not so much in terms of carbon source but as ‘signals’ for ...
