Dargin's Home 2019 Soil Test

Post by Dargin » June 4th, 2019, 8:41 pm

I started working on this lawn 3 years ago. It's approximately 2.3k. Northern mix. Nothing elite.

Up until last summer I was blindly amending the soil with dolimitic lime, calcitic lime, and 10-10-10. I realize I'm very lucky if I didnt cause any major soil problems in that time.

I -manually- core aerated and dethatched when I first started. I wouldn't do either again even if I weren't now aware of the potential drawbacks to both. It was...a workout.

I've also overseeded a couple times and done some spot seeding in areas where poa annua and nimblewill were a problem. Tenacity got those under control.

With the exception of a small area that took winter damage, the rest of the lawn is on a proper preemergent routine for the first time. I consider that a small victory in itself.

I top dressed it twice with compost/humus and once with peat during those first couple years.

Since last summer I nixed the balanced fertilizers and got my N primarily from milo. I haven't applied any forms of P, K, or micros since. I did apply some ferrous sulfate via MossEX this May just to test it out.

Plenty of KH/BLSC apps, extra molasses apps, and a couple light apps of corn meal. Mulched a lot of leaves last fall.

Winterized with a last second urea app, after some snow came and went. It really seemed to lead to a nice and speedy spring greenup. The lawn's never looked healthier, despite myself.

I've been mowing twice a week; occasionally 3 if it calls for it and the weather permits. Trying to get things to thicken up and fill in, and it looks like it's been working. Keeping the blades razor sharp (bought a cheap bench grinder) and keeping it at about 3.5 inches going into summer.

I took my samples with a bulb planter and sampled at the 3-4 inch range.

I think that's about it.

Thank you very much.

So, that's a pretty sandy soil with a TEC of almost 6. It has an OM% of over 5, so that probably means the mineral part of the soil is even sandier, and the OM is carrying the TEC forward.

In the cations, Magnesium and Potassium are low. Mixing 2 lbs/K of Epsom Salts with Milorganite/BSF every 90 days would help the Magnesium.

For Potassium, it's Sulfate of Potash ("SOP") at 2 lbs/K every month until September. Try to avoid applying it within a couple weeks of the Epsom Salts.

Phosphorus is plentiful.

Monthly apps of Milorganite or BSF is a good plan for Nitrogen.

Iron is good, and available at your pH.

In the micro's, Boron and Manganese are short - are those on the plan for 2019?

Thanks a lot, Andy. Yes on the micros please. I've got Twenty Mule, and have manganese sulfate on the way.

OK - then 3 tablespoons/K each every 60 days, as outlined in the Micronutrient Applications Guide.

Micronutrient Applications Guide is in the FAQ's section rather than Articles if anyone is having trouble finding it.

Are there any temperature restrictions on applying SoP? I did some searching but didnt come across the topic.

Sorta, but not where you'd expect them. SOP isn't recommended here after September or October, as there are some studies that indicate it can raise the likelihood of Snow Mold and Winter Kill, when applied late-season.

You're right, I wasn't thinking that end of the spectrum. Good stuff. Thanks.

It might hit 90 here tomorrow and I kinda have to pull the trigger. Had me feeling uneasy.
