Just a quick reminder that Dunkel's contains fulvic acid, the most plant active of the humates.

Started to read lot about Humic acid.

I alike the granular humate/ ore, with trace elements including gold, silver, etc, because it is easier to spread and till in. The more and more I read about it the more and more I understand a want it of course moderately applied. But it is also touted as a clay buster, so for my soil here....... its exactly what is needed. I cant wait to grow this year......its just something I can see, feel, and smell in my soil....... like the Jedi force within me....

I purchased mine from
http://www.greensmiths.com/index.htm
Check them out they have great products too.

May the force be with you.......Always......

I like the granular because it is easier to control and incorporate into the soil......spread it with a hand spreader, 1 lb per 100 sq ft.......I found the liquid humic acid a bit harder to control and ensure it doesnt plug up your sprayer during application..... One Cannot use a Ortho hand held on it......must use a pressurized sprayer.....

Humic Acid is highly beneficial to both plants and soil. I don't believe that higher rates are harmful although I would caution against indiscriminate foliar spraying. Here is brief run down of my usage the past two seasons.

In soil it can

(1) increases microbial and mycorrhizal activity
(2) promote nutrient uptake
(3) accelerate seed germination
(4) increase crop yields

Humic-Acid can be foliar and soil applied anytime to fruit set and beyond in one to two week intervals. Soil applied at 2 to 3oz/gallon drench. Foliar 1oz/gal/1,000 or full sized plant. Teas 1oz/5 gal pail.

Humic acid can also be used to fix chlorine from city water prior to brewing Compost Tea.

Steve, could you explain this chlorine fixing tendencies and what kind of environment and length of time is needed for this to take place? Thanks, BF

Dr. Ingham says if you add humic acid to your tea, it will change chlorine to a chloride. Chlorides won't kill the fungi & bacteria we try to grow in ACT.

The best bet is to bubble the chlorine out of municipal water for a while before brewing. You can also let the water sit uncovered for 24 hours to release the chlorine. But if you're in a hurry to get brewing this trick works faster.

Please read the many use advisements concerning humic acids. Mine is 12%. The suggested use for 12% is one ounce per 1000sq. ft per year. I split it and use only one half ounce twice a year with the fall and spring prep work. Generally I have seen over use as counter productive both in the books and in my patch.

WIZ,
Here is the stuff I use if i think I need it, depending on my soil condition at the given time. It is Humic Acid 70% and Folvic Acid 21% and is fairly cheap granular comes bagged in two different size chips. here is where I get it locally.
