Going with organic fertilizers help get the bacteria fed and going. Most soils have many microbes already in place and just need to quit getting hit with chems and get something to eat to start multiplying and doing their thing.

So, compost is a great way to start an organic program to a) make sure you have lots of microbes "in there" and b)to feed them and c) to add organic matter to the soil that will help with porosity etc.

But, as Dchall has noted before (I believe) you can get there all the same (or at least close to the same results), with organic fertilizers and practices.

Personally, if you have the time, money and strong back, I'd recommend at least one good "dose" of compost sometime. Essential? No. Additionally helpful, yes, would be the way I'd put it.

Your soil microbes (Mostly bacteria) found the CGM . So you are organically feeding the soil that feeds your lawn. But for a complete meal, you soil needs compost. I know, its "old school organics" labor intensive, plus it may be hard to find good compost. Good compost will contain many many species of bacteria, fungi, protozoa, molds, nematodes, micro arthropods (bugs), worms, and other living stuff. It will contain lots of organic material (carbon) which will slowly decay into humus feeding your soil microheard over time. It will attract and feed earthworms which will aerate your soil along with the longs strands of beneficial fungus. If you feel the need to put something down every week, then Let that something be compost

Ok thank you, guys! I'll try to get the compost on the lawn sooner rather than later ...
