HUMIC SUBSTANCES: STRUCTURES, (Special Publications),Used
Delivery time: 8-12 business days (International)
"Humic substances may not be beautiful, but they do beautiful things." Furthermore, these richly carbonendowed polymers are among nature's least understood materials. Twenty papers from the second Humic Substances [HSs] Seminar held March 27, 1998 at Northeastern U., Boston, delve into the multiple roles of HSs as acidbase buffers; binders to metals, molecules, ions, clay, and other polymers; water retainers (in the solid state); and catalysts and regulators in all life forms. Topics include: progress toward characterizing the properties of HSs, humic and fulvic acids in litter decomposition and composting, the implications for biological activity of the generation of free radicals by humic acid, HSs for enhancing turfgrass growth, and the humic acid solution to the greenhouse gas dilemma.
