None the less, if compost were to be had for sale, I'd buy it. It's a better
place to invest money than anything I can think of.
Many municipalities have compost for sale. They collect yard waste,
chipped tree trimmings, zoo poo, etc., and compost it in huge, long
rows, turning it with large equipment. What I do not know of is a
measuring system to determine quality and nutrient percentages.
Personally, I would not want compost made of yard waste.
