Does carbon sequestration help climate change and difference between natural farming and regenerative agriculture?
The tierra preta or Indian black soils are formed around the Amazonian village sites the combination of the deposit charcoal with ash and orgnaic wastes lead to sites where the acid and infertile red and yellow ultisols and oxisols were tranformed in to deep and peermanentiy imporved black soils with high productivity and sustainability.
A 3 meter black profile is found in many of the transformed sites represently a reservior of 300,000 kg Carbon per hectare which is equivalent to capture and storage of 1,000,000 kg per ha of Carbon dioxide.
The major limitation of cultivated soils are water air and nutrients and the black indian soil demonstrate this transformation has potential to address not only water air and nutrients but also the climate source of change which is too much greenhouse gas in the atmospshere and not enough organic stabilized materials to foster capture of water from percolation water and air retention and the ability to have abundant nutrients and habitat and feeding of the probiotic populations of soil microbes and fauna.
The Indian Black Earth was an inadvertent and unplanned experiment of sort.
If we take the results to heart we see than we can and should engineer the massive use of biomass to produce strategically biochar and bio energy. The energy to serve the global need for clean energy from renewable resources and the biochar for the transformation of vast areas of acid infertile soils in the wet tropics.
In Brazil the are of black indian soils has been shown to comprise an area of the nation of France.
Integration use of bioenergy with the development of biochar utilization provide a way to address real needs for energy while not utilizing a nonrenewable resource base stimulating energy economy and environment simultaneously while address the existential issue of exponenttial increase of greenhouse gases leading to exponential global warming.
Harvesting renewable resources for bioenergy the capture of biochar for soil regeneration and the integration of systemic approaches are a core for development of economies which can be both economic environmental andclimate friendly.
