That is windblown seeds of some sort, like dandelion
Thanks, that makes a lot of sense. We had gusty winds after the snow melt and I saw lots of dandelion like seed strands flying around. I was able to blow it if the grass easily.

I have already been doing NPK and PH testing for a number of years. I am working on adding new tools to the toolbox.
Look into Soil Infiltration Test, Bulk Density Test, and Electrical Conductivity(EC) Test.

Re: Did a few freezes kill off my winter rye overseeding project?

… Should I hold off on fert and see if some warm sunny days help it "green" back up, or just count my losses this year and focus on spring bermuda project at this point? Most of the cool season folks make their last fertilizer applications before the ground freezes since cool season grass roots con...

Re: Low Potassium.

You can also use mixed granular fertilizer from big box stores that has high K ratio like 10-0-10, 24-0-10, 32-0-10, 15-0-15, etc…

Re: Questioning Nitrogen Recommendations

They are just assuming the amount of P and K that the lawn will use. There is no way to tell the amount of P or K needed from a nitrogen test alone. There is no math involved it just an assumption. For every pound of nitrogen, ~1/4#P and 1/2#K will be used. If your mulching most of the P&K will go b...

Re: Warm winter, POA appearing

Looks like quite of few folks use Prodiamine. I've never used it but have had very good results with Dimension. Anyone have experience with both and found one better than the other? Thanks I saw this post from zeroibis in the warm season forum. I would add that Prodiamine is preemergent only while ...

Re: Do you guys rotate pre emergents?

My last 3 treatments of pre emergent have all been with Prodiamine and didn't know how important it is to rotate them? I rotate my fungicides with 3 different MOA's but you don't hear much about rotating herbicides. Herbicide resistance is real, it’s just a matter of time and combination of weed an...

Re: Soil test results

From the fertilizer recommendations, it looks like you’ll need 1 lb. of P for the front and back lawn; 1 lb of K for the front and 3 lbs of K for the back. You can do a 1 lb of actual nutrient / 1k sq. ft. by applying a balanced fertilizer (10-10-10, 13-13-13, similar) in the beginning of the growin...

Re: Soil sample

You can take soil samples anytime as long as the soil isn’t frozen. As mentioned above, amendments is best done during the growing season, with the exception of lime or citric acid.

My Plan was to do 10 yards per 10,000 SF. I was quoted $1400 so I wasn't sure if it's really worth it.
What does that include? Delivery, spreading, aeration, seeding?
When do you plan on getting done? Early spring or late summer would be ideal.

Re: Comparing Soil Tests in Thriving vs. Dead lawn area

There is nothing in the soil test results that would indicate the different growth results that you are having. I would look into the amount of sunlight direction, water, soil density, or possibly contamination from chemicals or nearby landscapes. Pics, description, history of applications of the tr...

Do NOT apply aluminum sulfate to your lawn. Aluminum sulfate is very dangerous to lawns, it can cause aluminum toxicity and decrease pH levels.

You’re probably thinking of ammonium sulfate 21-0-0.
