Thought I would share a paragraph from “Teaming with microbes” by jeff Lowenfels
“Vermicastings”
Vermicasting( the name given to worm poop) are 50% higher in organic matter then soil that has not moved through worms . This is an astonishing increase and radical changes the composition of soil ,increasing CEC because the greater amount of charge holding organic surfaces .Other nutrients,therefore, has the ability to attach to the organic matter that has passed through a worm.
The benefits don’t stop there the worms digestive enzymes (or properly those produced by bacteria in the worms intestines) unlock many of the chemical bonds that otherwise tie up nutrients and prevent there being plant available .Thus worm castings are as much as seven times richer in phosphate than soil that has not been through an earthworm. They have 10 times available potash; five times the nitrogen three times the usable magnesium and they are one half times higher in calcium (thanks to the calcium carbonate added during digestion).All these nutrients bind onto organic matter in fecal pellets .
