BIOENERGY FOR MINES
SOIL CARBON REGENERATION
Carbon sequestration is part of global carbon cycle, the natural interchange of carbon between the soil and the above ground environment. A natural process of accumulation and loss.
In the soil carbon is not inert as the organic matter with which it is associated plays a vital part in maintaining soil fertility while contributing to nutrient cycling and gaseous emissions.
Soils contain approximately three times more carbon than vegetation and twice as much as that which is present in the atmosphere (Batjes & Sombroek, 1997). Mining through the deposition of processed ore can affect the dynamic equilibrium that controls the size of the soil carbon pool as processed ore is normally totally devoid of carbon.
The ultimate source of soil carbon is atmospheric CO2 that is captured by plants in the process of photosynthesis. The plants add carbon through decomposition and incorporation into the soil is either directly as dead plant material or as organic matter that has passed through the animal food chain
Key elements of Selectra’s approach are;
The Selectra Process is all about organisation of the biophysical aspects (the overlap of physical, chemical and biological aspects of the local environment) in the development of the Agronomic Strategy.
Selectra retains the services of DR Johan Van Tol of Hydropedological Solutions as lead consultant.
EKO GEA BIOLOGICAL ACTIVATION
Biological activation of soils and plants is a critical step towards establishing the plantation. This is achieved by application of Biocomplex, a completely natural bio-activator that promotes bioremediation.
What It Is:
Oligosaccharides, the essential sugars that stimulate microbial activity, and
A complete range of pro-biotic compounds, trace elements and micro-nutrients, that are chelated, colloidal, and optimally balanced for ready uptake by the plant.
HOW IT WORKS:
EKO GEA's proprietary treatment:
Root Concentrate: Provides unique protection and growth stimulation during early growth.
Foliar Spray: A general treatment to stimulate plant growth in developing plants.
Plant selection is totally dependent on site specific conditions. Giant King Grass™ has proven to grow in various mine impacted lands after treatment.
Giant King Grass™ has a deep root systems which is ideal for taking carbon deeper into the soil where it is less susceptible to oxidation. Fisher (1994) has emphasised the importance of introduced deep-rooted grasses for increasing carbon storage in South American savannahs, while Gifford (1992), estimated that thirty percent of total primary production enters long-term carbon storage in Australian soils from roots.
