-Front (which includes the side area): ~5.75K, irrigated, mostly South facing. Northern mix. All is going well here. No complaints.
-Low-Input: 5.5K, lower maintenance. Northern mix, with Fine Fescue in many areas. Only irrigated when in immediate danger of dormancy…several times per year. Hardly ever do biofungicide apps on this area. It’s coming along, but the soil could still be improved. I’m surprised that the Calcium number is all of a sudden lower this year. Then again, it’s been a while since a test has indicated the need for Lime.
-LF (~1,000 square feet). This area is tricky. I’ve tested it before as well, but not since 2019. I’m currently doing a KBG reno on it (kinda late; currently in sprout and pout stage; thankful for the warm October). I’m also looking for any soil remediation items that could help improve drainage. This area is prone to ponding (and ice in the Winter). I don’t care that the TEC is low in this area, and I have no desire to add more OM to it…I actually want it as sandy as possible to help the drainage. Problem is, while the TEC is low, the soil is extremely fine…like silt/clay, and that does not help drainage. I’ve been digging some rudimentary drainage, and this is helping, but anything I can do beyond that in regards to soil amendments that might specifically help with drainage and percolation speed? I keep saying I’m going to do a jar test to ascertain the soil structure for certain, but I haven’t gotten around to it. But there is apparently a ton of silt, and it turns to mud easily. I will not be mulching any more leaves into this area; it just seems to make the drainage problem even worse (and creates a dirty mower and pants!). I just want to have decent drainage and decent grass here. Nothing spectacular. No one really sees this area.

K: Been applying this macro nutrient has been my main focus since last year’s low numbers. The disease tolerance was terrible last Fall and Summer performance a bit lacking; I think the low-ish K played a role in both issues.
Mg: I haven’t been great at keeping up with this one…I did a couple of small apps since last year’s test, with Epsom salt and/or Sul-Po-Mag.
Fe: I haven’t been going crazy with it. A little here and there.
Boron: what the...?! It’s supposedly back down everywhere again. Starting to wonder about sampling reliability (this one’s on me) and testing reliability (on the lab).
Thanks for the help, as usual!
