Wouldn't it be great for a whole bunch of glucose molecules to be together in one package? Well, plants thought that was a cool idea. They hook glucose molecules all together in such a way that the long chain curls all around and forms a big globby polymer. That's starch! Whenever the plant needs energy, it can chomp a little glucose off of the starch. Chomp! mmmmm!
Humic acid is a carbon-rich extract produced from fossilized organic matter. The powdered form is highly concentrated, allowing large quantities to be transported easily. The powder is water-soluble, which allows a large quantity of concentrated humic acid to be produced as needed.
