I've got an approx. 3 acre lawn which I had soil tested for the first time this summer and got the results around August 1st. I glanced over them and promptly filed them away for later review...well, it's later (3 months I know) and I finally looked at them as I'm ready to do my fall application and I'm a bit confused as to where to go now. I split my samples into 3 seperate ones and marked them "West" which is irrigated. "East" which is the same and "out" which is about 1/2 of the lawn which is non-irrigated. I leave my clippings on in all cases. The tests say my "out" area should get 1lb N/1000, (33-0-0)once a season in early Sept. The "West" should get 3lb N (33-0-0) 3 times yearly May 20-June 20, August 10-Sept 10 and October 10-October 31. The "East" should get 2lb N 2 (20-0-10) 2 times yearly August 15-September 10 and October 10-October 31. I've always done my pre-em in the spring (went this year to 2 apps of 18-0-8 Dimension), a summer feed and a feed around now. All of this property kind of flows together. The East and West which are irrigated (approx 1-1/4 acre) are irrigated and are my "nice" lawn around my house. Am I over thinking this and just choose a happy medium? I could really use some advice. The lawn is pretty good the way I've been doing it though I mow (at 3-1/2-4") every 3-4 days on the irrigated stuff. I'm in Minnesota just South of the twin cities. Sorry for the long winded post.
