Answer:
"How To Grow World Record Tomatoes" is a book written by Charles Wilber. He describes how to make Kudzu compost, grow cover crops, and other good gardening practices. He grew 20 ft tall Better Boy tomato plants, 15 ft tall Silver Queen corn, huge radishes, Peaches the size of grapefruits, and lots of other stuff with that compost. The Mother Earth News magazine wrote a few articles about him about 25 years ago. His compost recipe, which includes colloidal clay, is included in the book:
3 inches of "hay", coursely ground (mixture of dried Kudzu and Sudex)
2 inches of cow manure or 1 inch of chicken manure
Quarter-inch of garden soil
Hardwood ashes or granite dust (light sprinkling)
Colloidal clay (light sprinkling)
NEVER let it get rained on!! Keep it covered with a tarp. Heavy rains will leach all the nutrients out of the compost.
Include some fresh, shredded green Kudzu in the "hay" layers. I'm not sure what type of colloidal clay he used, but I know that Zeolite and Bentonite are types of colloidal clay. Considering that he mentioned using colloidal clay as a source of phosphorus, he may have been using colloidal phosphate. (soft rock phosphate) If you can't find any Kudzu, just use some other legume, such as alfalfa, soybean plants, beans, clover, or hairy vetch.
For more details, buy his book on Amazon. It's not expensive at all.
