Having spread my fair share of manure onto more than my fair share of fields, I assure you that supply and labor are not a problem. Feedlots around the US are dying to find ways to get rid of their manure. The labor involves driving in circles and is part of the life of farming.
The problem with feedlot manure is it's more like septage than manure.
The basic idea is to delete them in water 1/2pound to 5gl. then water plants with that. The idea is diluting and caffeine & acid left from brewing. I agree with the rinse but I don't belief it's needed with all plants.
Our family has been dumping coffee grounds around rose bushes for three generations.
If you might like my other journal, "Coffee Bowl"
oh my mistake i thought you meant fertiliser for an aquarium.
my mum puts coffee around garden plants too :P
Can pet manure be sterilized chemically to make it safe?
There are chemical sterilants such as methyl bromide and others that could be used, but the cost and bother is probably not worth the value of the manure. Also, the average homeowner probably is not equipped to handle chemical sterilants. CONCLUSIONS
The health hazards associated with cat and dog manure are greater than the potential benefit from its fertilizer value. Cat and dog manure should be disposed of by flushing down the toilet, burying deep in the soil (six inches or more) or by placement in tight plastic bags for garbage collection.
Be careful with this. It isn't a joke and the appropriate measures should be taken.
Since you're putting this in the substrate then putting your arms in the water(presumably) afterwards, it is a good way to introduce contaminants back to you and your family. I spoke to Emmett Schulte and UW and he confirmed this with me. The dog feces in water will still be dangerous and requires 5 or more days composting over 165 degrees to render it "safe".
I was going to ask if you did a barf diet! Then I finished your post ha ha. My grandpas son had that with his dog ( no not uncle, divorces blah blah...) He had a really expensive dog and when he bought it, that was in the contract for it, that he had to feed her a barf diet.
