Plant-driven sequestration of carbon. Note the extension to rootzone depth in subsoil.

1. GEOMITE CARBON SEQUESTRATION
Trial January-July 2012
The figures for sequestration are as follows:
 Two applications totaling an equivalent of 100kg/hectare were made during the seven
month period
 Colloidal Organic Matter increase as recorded by APAL analysis showed ;
Top 15cm……………..3.05% - 5.62%
 COM increase to depth:
15cm – 45cm………..3.05% - 5.27%
 This represents a conservative estimate of 10 tonnes/hectare for the period and is of
special importance by virtue of the depth achieved, as oxidation rate slows with
increase in depth.
 The ‘smorgasbord’ concept on which Geomite is based suggests this as the result of
microbial propagation induced by exudate nutrition.
 The figures suggest commencement of a Terra Preta profile development and if normal
procedure is followed to slow carbon oxidation during the dry ‘null’ period, there is no
reason why any soil may not be elevated to peak fertility within 3-5 years.
 Although this carbon is ‘active’, therefore subject to slow oxidation as part of the soil
carbon cycle, it should be noted
(a) that this increase occurred over a six month period.
(b) that increased colloid shielding due to production of humate in-soil by
Geomite will maintain the annual carbon increase. In regard to cost of
carbon sequestration, note that 10 tonnes of carbon were sequestered in
six months by an equivalent of 100kg/hectare of Geomite at a retail farm
cost of A$60.
 Equivalent sequestration by biochar, 10 tonnes @ A$3000 would equal A$30 000.
 Although the Geomite carbon is active and subject to slow oxidation, it extends to depth
and is augmented with each application of the fertilizer. The carbon credit potential of
Geomite is still to be verified by independent duplication as per scientific method and
this must be the first consideration once manufacture is under way, however it does
suggest high returns for the entire supply chain.
