I've tested soils with huge amounts of organic matter that were poor in Supramolecular Humic substances. The point I believe is that the term Humification is inaccurate as Humus (Humic substances) are not derived by the simple act of organic matter decomposition. Test any high quality finished compost and you won't find significant levels of Humic acids. That's proof! Humic substances are not the 'Active Carbon' fraction of a soil as HA's will last for thousands of years if not disturbed.
It's not just about organic matter levels in the soil. What's more significant is the carbon that is not rapid cycling, the fraction that's a powerful biologic chemical called Supramolecular Humic Substances, which are not derived by the simple act of organic matter decomposition. Testing for organic matter will not find these chemicals. Supramolecular Humic Substances have a Cation Exchange Capacity dozens and even hundreds of times stronger than soil organic matter.
I think that is a very important issue that you raise. Can you tell me how we can measure that ? And how we can produce these Supramolecular Humic Substances ??
Our familie procuces compost from green waste and we are really looking for techniques to improve the quality of it. Regards, Mark@van-iersel.eu
building soil...it's a beautiful thing
