There are some interesting possibilities hinted at in this presentation:
What I took away: lipids and carbohydrates feed the fungi, leading to long-term humic acid development in the soil. Fungi are your long-term soil builders, not bacteria. Bacteria return the soil to just its component minerals without adding in much, if any, long term humus. Adding nitrogen to fallen crop residues increases bacterial breakdown of the material, leading to a fast composting process which leaves next to nothing. Higher lipid (fat) content in plants provides more for fungi to eat and makes for healthier ongoing soil and crops.
The makers of the video sell a product called Rejuvenate, which feeds fungi:
“At AEA, we use our microbial stimulant and soil conditioner, Rejuvenate™, to help farmers care for the microbial life in their fields. Made from a combination of humates, molasses, and trace minerals, Rejuvenate™ performs three important functions.“
The functions it performs, according to the website, are:
1. Assists in the decomposition of fall crop residues
2. Suppresses overwintering crop diseases
3. Improves soil structure
Since fungi feed on carbohydrates and apparently adding lipids makes humus stick around longer, my approach to composting everything is yet again backed up by SCIENCE(TM)!
Compost meat and fat and oil and sticks and logs and everything. Long-term soil fertility ensues.
