I'm running a leaf compost. It's a pretty big scale. I pick up leafs from all the neighbors chop them with a special purpose tool and then store them for a year in multiple 250 gallon bins. The end result is about 150 gallons of humus per bin after the year after I mix in compost and they decay down. I'll probably do four bins this year, so 600 gallons of humus.
Is there a place I can send a sample to to have it tested for toxins and pesticides? Should I just assume that it's safe to use to grow food in?
