There's a huge interest in using CBD oil/extracts and infused products containing CBD as medicine. Soil Secrets with the cooperation of a professional medical cannabis grower did a grow out experiment with spent/used soil compared to brand new Fox Farm Forest Floor soil. We cleaned the used soil using our Soil Secrets trommel screen and the treated the used soil with molecular biology made by Soil Secrets. Most growers throw away soil after one use so wanted to see if the used soil could be made good and repurposed for a second or third use. The image provided is from the starvation group where no fertilizer input had been provided to either the SS treated spent soil or the brand new Fox Farm soil. Both groups were treated with a Mycorrhizal product and bacteria. The Fox Farm was treated with the mycorrhizal product called Great White used per label instructions. Great White also contains a bacteria blend. The SS spent soil was treated with the Soil Secrets mycorrhizal product called EndoMaxima and the Soil Secrets Microbial Consortium BIOpack for the bacteria. The image I'm providing clearly shows that the Soil Secrets repurposed soil grew larger and healthier appearing plants than the Fox Farm soil. The plants have been stepped up int o 15 gallon containers using the same soil treatments so our next step is to test and measure the yield from the plants and measure the THC and CBD concentrations produced from all the groups. Stay Tuned for those results.
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
