“…The realization that soil C reservoirs can be important in addressing climate change (e.g., Lal, 2003;Sohi et al, 2010) has helped to foster general appreciations of the value of organic carbon in agricultural soils (e.g., Fowles, 2007;Mondini & Sequi, 2008). Terra Preta, as its charcoal C appears to be recalcitrant, has been viewed as a potentially important public policy model for improving soil quality for agriculture and serving as a means of redressing anthropogenic releases of C to the atmosphere (e.g., Day & Hawkins, 2007;Navia & Crowley, 2010;Sohi et al, 2010).…”

Studies of Terra Preta soils have generated interest in recreating their fertility elsewhere. Much of the research has focused on soil amendment charcoal ("biochar"). Terra Preta also contains bone fragments, producing a high concentration of phosphorus. Some forecast worldwide declines in phosphorus supplies, and better agricultural system management is required to improve phosphorus use efficiency. A conceptual model is offered to consider the influence of charcoal on bioavailability of phosphorus. The model describes a system where improvements in the chemical and biological condition of the soil result in increased phosphorus availability and cycling. Mechanisms of phosphorus/charcoal interaction are considered, and an
