[Terrapreta] dead zones on sea coasts

[David Yarrow]

one understated benefit of a TP carbon char strategy is the reduction in chemical water pollution leaching out of farmland into watersheds, over-enriching waters and creating a variety of microbial outbursts.  adding char to soil dramatically increases soil's capacities to hold onto nutrients (esp. N, P & Ca), and avoid their loss by leaching.  less loss means less fertilizer needs to be applied to the soil.

the ultimate destination and consequence of agricultural run-off are dead zones along coastal areas, river mouths and deltas.  scientists who study these dead zones now use special satellite imaging, and predict dead zones will double in another decade.  the link below is a short but informative report on scientific assessment of these dead zones:

pyrolysis of sewage can reduce the second major source of dead zone enrichment.
