Urea is anything but organic. If you want to go organic you could hit HD or Lowes and beat the garden center mgr up & down to get a 'wholesale' deal on a 1/2 skid of Milorganite 6-2-0: http://www.milorganite.com/professional/uses.cfm (But I'll bet ya a Blatz you won't get the same deal Smallaxe gets in Milwaukee ! ) ___________________ Or you could do what we do, and contact your local grain elevator or rural farmer's co-op for current availability of high protein grain meals such as soybean meal (6-1-2), alfalfa meal (3-1-3), cotton seed meal (6-2-2), corn meal (2-0-0), or... hell...THIS late in the season you'd get away with using blood meal (13-2-1) without a whole lot of fear of burning the turf. The thing about blood meal (typically derived from either swine or poultry) is that the rate of application (maximum 5# / K sq ft) is EXTREMELY LIGHT compared to that of the aforementioned grains (15# - 20# / K sq ft). But bear in mind, blood meal is typically 2 to 2 1/2 x more expensive, too. And, of course, also understand that some folks on your list may take issue with you using an animal-derived product like blood meal on their lawn.
