First, I just wanted to thank everyone at Lawnsite for all the knowledge they share. I passed my Ornamental & Turf, and Industial weed control license test on the first attempt and could not have done it without reading thousands of post and replies in my off time. I really learned alot from Ric. I realize that I am very new and still learning. My question is about a common bermuda lawn that is 45,000 and has no irrigation. It has no prior fertilization. I took a soil sample the the results showed very low in phosporus and low in potash. I don't have the exact levels with me now, but I can post them if needed. The ph is 6.2. The test suggested that I apply 3lbs/k of 34-0-0 and 8 lbs/k of 0-20-20 in May and June. I feel like a need another N application with some slow release, but what I was in question about was the 8 lbs/k of 0-20-20. I know that the standard 0-20-20 around here has all MOP. Since my potash levels are this low, don't I need to use SOP because to the chlorine levels in that much MOP. I have read a lot of post that talk down MOP. I went to Lesco to buy some 0-0-50 SOP. The lesco website descibed it as standard particle size. After I drove over a hour to Lesco, the sales guy said that it had to be sprayed. I thought standard particle was spreadable. The Lesco guy said that chlorine wasn't a concern with MOP, MOP is just as good as SOP as well as cheaper, and that is what I should use. What does everyone else think. Also Lebonon turf doesn't sell straight fertilizer near me.
