Best organic lawn fertilizer on the cheap?
I'd like to try using organic fertilizer this year, but it seems quite expensive. For instance, feed stores around here are charging $10 per 50# bag for soybean meal, which I like because of its high nitrogen content. If my lawn is 7,000 square feet, wouldn't I need about two bags?
What are the best deals out there right now for buying organic fertilizer in large quantities from the feed stores? How much are corn meal, alfalfa, and the others selling for right now? Which organic fertilizer gives you the most bang for the buck at today's prices?
I tried going the free route by getting used coffee grounds at Starbucks, but they would only give us small quantities of UCG, so it doesn't work so well for our larger lawn.
