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.
I was recently asked to provide a simplified explanation on the importance of Cation Exchange Capacity (CEC) values. My Response: CEC is the ability of a soil to hold onto plant nutrients. The finer the particle size the higher CEC value, generally speaking. For example sand particles are course and visible to the naked eye, where as clay particles are fine and are not visible to the naked eye. So clay will have a higher CEC value than sand. It is obvious to most of us that sand cannot hold onto water or nutrients as well as a soil with a finer texture. Therefore, soils rich in Clay and Loam size particles are universally recognized as being better for farming - CEC explains this. The numerical value for CEC represents how much nutrition can be held by a given amount of soil. For example one pound of a clay loam soil with a CEC value of 20 will hold 4 times as many nutrients as a sandy soil with a CEC value of 5. 20/4 = 5 . It's all about math, for example Nitrogen in
