I have a customer that has a lawn that is not responsive. The lawn has a great deal of moss and is thin with slow growth. The lawn has a good amount of shade in the back, but so do the neighbors and their lawns are in better shape. I have been using Natures Safe Organic fertilizer on the lawn the past two years with no improvement. I just did a soil test and this is what I found. Ph 6.0 Total Exchange Capacity 12.01 Organic matter 3.68 Sulfer p.p.m. 14 Easily extractable Phosphorous 43 Calcium 3070 Magnesium 416 Potassium 72 Sodium 29 Base Saturation Percent Calcium 63.88 Magnesium 14.43 Potassium .77 Sodium .52 Other 5.40 Exchangable Hydrogen 15 Boron .42 Iron 281 Maganese 11 Copper 1.53 Zinc 3.74 Aluminum 474 I realize the Potassium is way out of wack. I was also wondering about the ratio of Magnesium to Calcium. Can anyone advise me of a plan to rectify these numbers? Also if you see somthing out of wack let me know as I am pretty green when it comes to soil tests. How does the exchange capacity look? I believe I have access to 0-0-38 PCSOP w/Mn Mg it has 3% Fe, 3% Mg, and 5%Mn or 0-0-45 poly coated potassium sulphate that containes 16% S I believe I would want the former as its K comes from Sulphate of Potash rather then the Potassium sulphate. I believe the Potassium suphate has a higher salt index and greater burn potential. Please correct me if I am wrong. How much should I apply, how often? Any ideas on a battle plan and time to retest the soil would be wonderful. Thanks so much.
