I have never applied humichar but I am thinking of adding to my soil soon, but based on soil tests will need to add high potassium fertilizer as well. Are these safe to apply this time of year, particularly late May?

Is humichar DG snake oil? Thoughts?

Can't comment on the snake oil part, but you should be safe to put HumiChar down at any time and as often as you want. From what I understand, it takes a longgggg time to provide changes in your soil - like years.

Humichar is not snake oil as long as you aren’t doing it for liquid aeration reasons. That and carbon pro g are good products

I used humichar all winter and threw down a 0-0-45 potash and I had the first fully green centipede lawn in the neighborhood by a few weeks.

I've wanted to try it but $90 for a 40 pound bag is a little salty after already buying fert, grub preventative, pre-emerg, post-emeeg, disease/fungus, etc.

You might be interested in this kind of thing.
Root development after a summer of testing products.
This guy is in NC.

Humic test plot update:

quote:
Disclaimers: In fairness to Matt, I suspended the Carbon-X test for part of the season to work on a phosphorus deficiency. Also, the GCF products had a one month head start on K4L's Extreme Blend.

Root pictures below. Most of these had more root mass than pictured, but the soil was pretty sticky so some root mass came off in the wash unfortunately. I would say each of these had some roots in the 4"+ depth despite the terrible soil. The Air-8 sample was easier to clean than the others due to noticeably better soil tilth (not crumbly infield clay, but better than the others), which IMO lead to more intact root mass for the picture. If that continues through next year, I will conclude Air-8 is worth my money for the soil tilth improvements. Anecdotally I'm happy with the Air-8 results, though I still don't know how the science holds up.

The cores were all pretty easy to pull, but we've had a good bit of rain lately too. There's still no difference in visual appearance across the test plots (this has been true throughout the season - not due to the recent rainfall). The next tests will be fall/winter color and spring green-up. Will provide a picture closer to dormancy.
