I found this link on using BioChar to build soils and reduce CO2 emissions. Whether you agree or disagree with climate change, having high levels of soil carbon (not just organic matter, they are different) will make you soils more productive and increase your nutrient holding capacity. This was an interesting read, even though it is a little long.

Our new product TRIO has a small amount of leonardite (a naturally occurring carbon source). This product will help keep calcium in the root zone in soils that have low carbon levels, such as sandy soils.

If you have had experience using carbon in your fertilizer program or want to know more about TRIO, I'd love to hear from you.
