One of these days you are going to take my advice and come to the realization that organic fertilizer is snake oil. The plants don't give a rat's azz in what form its vitamins were derived from in the past tense. N is N if it comes from animal crap, oil, or a thunderstorm. The plants to look their best need regular high nitrogen feedings to sustain leaf growth and overall color. But if you guys want to haul, handle, and apply 100 lbs. vs. the 25 lbs. of material I would I apply be my guest. You may be able to sell that organic sales pitch in some of the metropolitan high-end areas but where I live people buy the best service at the lowest cost. If you want to build up the organic content you should just apply compost.
