Mike & Randy - let me clarify. We are in the business of growing grass. Grass does not care where it's nitrogen source comes from. We are in the business of manipulating grass for whatever reason, be it a lawn, golf course, etc. To get the proper # of N to grow healthy grass, you will use a lot more organic fert. The basic difference in organic vs. "chemical" fert. is in the amounts of nutrients available. Organics do supply microbes, but only those that have not been processed for safety in handling i.e. Milorganite. Also of note it that some organics have offensive odor. Am I going to use an offensive smelling fertilizer on one of my millionaire accounts? Not if I want to lose the account. If we were to treat only the soil and not the plants, we would be using compost on every lawn and mulching, not bagging, the clippings. We would also be mulching the leaves into the lawn and not removing them, either. This may be realistic for some, but not others. Fertilizer will NOT kill soil microbes, if it did, it would be labeled as a pesticide. BTW, I do have a strong background in chemistry (4 yr) and soil science (2yr).

Excessive fertilizer salts will inhibit microbial activity. Think CHLORINE might sanitize? Ammonia?

Compost has very little nutritional value in most cases and is not considered a fert as much as a soil amendment. Mulching is the ONLY way to go and if you aren't because you're worried about your million dollar clients, ours don't have a problem with needing LESS fertilizer and improved soil as a result.
I DO mulch MY leaves into my yard but no, it wouldn't be acceptable for most paying customers.
Maybe YOU'RE in the business of manipulating the grass for profit, I make a living taking CARE of the earth and trying to improve the living conditions on OUR planet. The fact that it makes lawns BETTER is just a fringe benefit.
You claim the knowledge, ought to know that stuff.

You don't know as much as you think you do.
