One other relevant piece of info for YEM and others: I recently found out that the North Haven SiteOne store has been closed indefinitely starting in 2023.

You're welcome. I knew I couldn't have been the only person who noticed this on the bags a few years ago. For now, I guess we need to expect our area sometimes still being considered part of the "Northern tier", and sometimes labeled "beginning of transition zone", both used loosely in meterorologic...

Indeed. I found a document by the PNW Extension, published in 2022, titled "Fertilizing with Biosolids". Pub #508. It contains virtually everything anyone would probably want to know about biosolids, including the nutrient analysis, why it is what is, and much more. In it, they confirm the ammonia N...

Here is a direct quote from the wikipedia article "Climate of New England", if I may: "Coastal Rhode Island and southern Connecticut are the broad transition zone from continental climates to the north, to temperate climates (called subtropical in some climate classifications) to the south. In this ...

That said... According to the bag, I am essentially using the transition zone rate under program 2 on that label you posted (it says 3.82 lbs per thousand, and I'm using 4.0 lbs, and getting good 4-month coverage from it). I'm slightly more inland than you technically, but we are not far from each o...

Hope you don't mind me bringing this thread back after 2 years, but I noticed it got no replies back then, plus you replied to a post of mine very recently, and I wanted you to know I saw this same map on these bags a few years ago. We are in the same part of the state, too. Back when I saw this, I ...

Interesting. 3.6-3.75 in is my preferred height. Sounds you you got there with the "spiked" wheels.

I'll wait HOCs over 3.5 inches, no boundary wires needed, better security features, and programmable week-to-week adjustments for no-mowing windows (e.g. due to frost) and ability to only mow certain areas. Morph, It doesht mulch leaves/suck up debris, right? Also, if you have a disease and need to ...

Oh, sorry...I literally meant what it is. My gut feeling says ammonium Nitrogen, based on the response and based on the smell when a low rate is used in hot weather (likely losing much of that fast release N fraction to the air, unfortunately, if not watered in soon after application).

By the way, Morph:

Do you know what the water soluble N fraction of biosolids is? No one seems to know...

Yeah, neither is mine. No lawn around here is, actually, but I know I said that last week already. Lawns are definitely trying to green up (today was 56), but Saturday might top out at like 30. Thankfully we mostly had a break from rain for 3 weeks.

Morph, To get you started, look into the TTTF cultivar "Summer". It's about two-thirds of the way toward a full dwarf cultivar. I have had good luck with it. It's not known as a higher-rhizome variety, so, like most, it will clump (but you shouldn't notice most of the time). It blends moderstely wel...

Morph, Yes, I would no longer use Poly coated urea in a winterizer app. This was 10 years ago and I was trying things. Today, I use a blend of primarily fast release ammonium sulfate and urea, (with some high-activity methylene urea added in for insurance against lagging Winters or warmups) for my f...

I originally posted this topic almost 10 years ago, and apparently this question about how Lesco labels their products has been rolling around in my subconscious this whole time, slowly being solved. Last night, I spent at least 15 min. doing some back-of-the-envelope calculations, and I have it fig...

Morph, With a robot mower, and certain Turf type Tall Fescue culitvars trained to a lower cut, you can even get away with a sub-2-inch mowing height if your surface is even enough. I know you're not a low cut guy, but I also know the robots don't currently cut quite as high as rotary mowers can. Gen...

Going a bit further: I use proportion arithmetic and cross multiplication of the fractions to convert one concentration to another. For example, the Lebanon Seaboard "Preen" brand product you referenced is Dimension 0.19% (pretty strong, so not as much will be needed). Using a 0.15% product as a ref...

Of course, these active ingredients come in different strengths. But the most common concentrations I've seen and used are 0.15% Dimension, and 0.37% Prodiamine (or thereabouts). I tend to use more Dimension than anything, but sometimes use Prodiamine or other active ingredients, too. I find that fo...

Agree with all of the above. How it shakes out will be interesting though. As far as grass, I embraced Tall Fescue when I started with this stuff, 10 years ago (mixed with the most drought tolerant KBG cultivars I could find). I knew what was happening with climate and picked grass types accordingly...

Also, good tip about the potential for heat when mixing. Will probably need to add water slowly with good agitation, and then let the solution cool down before use. The Potassium Carbonate salt I ordered is denoted AD640 everywhere it's sold. I'm not sure if that's a catalog number from the maker, o...

Thanks, Morph! You're always so full of other practical chemistry info, which is great. The rug cleaning bits are so helpful, too. Actually, you reminded me of something I wanted to ask. I'm not sure if the stuff I ordered is anhydrous or hydrated, and whether it really matters anyway as far as amou...
