Soil Carbon Sequestration is Building Top Soil. These two images were taken at our arboretum in Los Lunas, where 32 years ago the soil was a salty high pH clay with terrible structure. The images showing the cracking and light colored clay is the before Soil Secrets. Using the Biomimetic Soil Ecology protocol of Soil Secrets we’ve stimulated and instigated the process of top soil development which requires that carbon from the atmosphere is harvested by plants and turned into a molecular form in the soil that allows for long term storage. The image showing the darker soil with aggregates is the same spot the arboretum after three decades of Soil Secrets treatment.
