Boosting your soil's OM is a years long process (especially when starting out in the 1-3% range), and there are no short cuts. recycling clippings and using organic fert is a good start, but I've come to learn, as a novice myself, that that's not enough to see any significant change any time soon. Really the only foolproof way to boost OM relatively quickly is by dumping heaps and heaps of organic materials on the lawn. Compost, peat moss, shredding your fall leaves (and your neighbors fall leaves), saw dust (although be careful here. You can create serious N deficiencies for your turf by piling on saw dust), used coffee grounds, etc. Lots of hard work and as often as your lawn, body, and wallet can handle. Don't fantasize and obsess over OM, as it's not the end all be all. Play the long game and do what you can, when you can, and you'll see gradual improvements year after year.
