Organic... a general term. Natural? Synthetic organic? How synthetic? Any more, most companies that sell "natural" organic fertilizer synthetically modify their products.
"Natural" organic fert can contain dangerous pathogens, contaminants and hazardous dust particles.
Manure runoff often causes many lakes & rivers "off limits" for swimmers.
We stopped offering "natural fertilizers" some years back because we were concerned about health issues. We prefer to use professional products designed to be used in the green industry. Too many folks have children, grandchildren, dogs, cats, etc. Customers also prefer non smelling products.
We offered natural organic fert on a trial basis. Now we use clean products that work, don't smell, don't contaminate, and homeowners can walk on their lawn immediately (granular) or when it dries (liquid).
my 2 cents after 35 years
p.s. The day care centers who are customers also prefer non-organic because they have googled (after my recommendation)
