ents. As a result, aggregate habitat is created to play an important role in filtering, retaining, and draining water.”
Microbial communities also support carbon sequestration, using light energy converted into chemical energy( carbon compounds via root exudates) that is stored in the soil during photosynthesis.
To accelerate carbon sequestration and advance soil life through microorganisms, Van Graan has been generating biochar, the charcoal produced from plant matter( biomass).“ When used as a soil additive, it not only removes carbon dioxide from the atmosphere, but it creates an environment conducive to boosting microbial populations while building soil structure, reducing soil acidity, and generally decontaminating the soil. Because it is so porous, it absorbs, retains, and aggregates water and increases organic soil life, ultimately lowering the need for inputs such as additional water and chemical fertilisers.”
Below: Henk van Graan demonstrates how biochar, combined with composted grape matter and recycled water, enriches soil life and boosts carbon capture on the Nederburg farm.
