I'm not judging your program -- I'm just trying to understand how it works. When distributors or salesmen suggest I try something, I first run it through the sniff test. Does it make sense? Does it make sense that 0.03# N/M or 0.9# K/M is a useful app in LCO situations? Even in true foliar spoonfeeding programs on golf course putting greens, where they're delivering no more than 2 to 3# N/M/yr and applying at 7 day intervals, the lowest application amounts are 0.1# N/M, a full 300% more than the amount you're applying to lawns. To me, something doesn't add up. I also don't get the "it works for me" thing. Plants are plants -- they don't care if you are applying it or if someone else is applying it. If you're getting desirable results from your apps, I think you should know why. Any old lawn boy can put something down and get some kind of result. If we want to be professionals and be regarded by others as professionals, we need to know why our applications work. The electrician I hired last week told me exactly why he did the things he did to bring our office back online and why they worked. We should be able to explain why we do things and why they work. I just don't understand why the low rate of KNO3 is needed or why the micronutrients are needed. Not judging you -- just trying to understand.
