I am so impressed, Clay! This is one of my biggest soap boxes. The only problems with our poo is that we are omnivores and we take lots of drugs.
Do you have human poo mixed with sawdust and thoroughly decomposed available? You are one lucky person to have this resource. In the states it is federally supervised and tested 5X...before it is available to the public. After decomposition (I think this is done anaerobically), the ingredients are not at all the same chemically. Smells wonderful. Looks beautiful, a dark taupe color. Fine fine textured. No rocks. No clumps. No sticks. No chunks. No pesticide residues and no weed seeds.
This was the only mulch I would use to mulch plant beds. I refused to use bark, chips...non decomposed organic matter. I never lost a single customer.
You should ask for a readout of a test of the mulch. You will KNOW what is in every batch. What this stuff does for a landscape is phenomenal. I am not kidding. Adds a tiny bit of nitrogen but it feeds the soil, the soil organisms work symbiotically with plants. Inside ONE WEEK, after installing this for mulch on the soil of the plant beds the plants look amazing. My guys, my crews were blown away at the difference. Gorgeous.
There is ONE bad thing about mulch made from human poo and that is heavy metals. Humans take medications that are made with heavy metals and that is distilled and pooped out by humans. I've never used this mulch in my vegetable gardens. BUT! Knowing the amount of heavy metals in our tap water and now our soils is making me WANT to use this mulch on my beds in my greenhouse.
I refused to use any other mulch on my landscapes; new or maintained. My bosses flipped but I stood my ground and never lost a single customer. The landscapes I maintained sold my basic basic techniques and my bosses backed off. Let me make the decisions and sell.
And make happy solid customers.
In the commercial world that won't fly. Very very sad. I asked (Sawdust Supply, Seattle, WA) the owner, great guy, what happened to the poop that wasn't decomposed and made into mulch (Gro-Co) and I was told happily that it was trucked to the center of Washington State and pumped 15-20 feet below the commercial crops. I heard that he thought that benefited the crops somehow?
Gulp. If you think about it, root zone is 6" max. Pumping our poo into the ground 15 to 20 feet deep means it is going into our fresh water systems. Our government is dumping our poo into our water tables...our fresh water systems. Without testing, monitoring or public knowledge.
Clay, please ask pointed questions of your municipality.
