Greetings all. This question is probably best answered by someone who farms, maintains golf courses/parks, or has acreage. I'm a city boy moved to TX trying to learn your secrets. My neighbors and I have about 2 acres of lawn. Buying fertilizer by the bag (i.e. 5,000 ft coverage for $20) just doesn't make sense...particularly if you're doing it 3-4 times a yr per local experts. I had my Dallas area soil tested by those brainy people at A&M (thank you). It turns out that my P & K are ideal -- which apparently is very common in this area due to the clay. They recommended 100% nitrogen. I guess too much P&K is bad and adding more is unecessary and unhealthy. Question: farmers must have to apply comparable fertilizer in bulk. And I know they do it for other things (herbicides, pest control). And I don't think they buy it by the bag at Lowes. Can I go somewhere and purchase a good comparable slow release fertilizer in bulk? Neil Sperry's brand (as an example) is a 24-0-0 w/ 60% slow release in granular form, but it's $34 bag times 20. http://www.neilsperry.com/pages/neil-sperrys-texas-best-fertilizers.html We've got an earthway broadcast spreader and can dial in exactly 1 or 2 lbs/1000 ft. And I live close to farm country here in the suburbs of Dallas. It sure would be nice to buy bulk of good quality fertilizer w/o the filler and costs. Anyone care to share their thoughts and recommendations? You'll help us out in convenience, cost, and curiosity. Richard
