From One Farmer To Another
This is conversation between Mark and Rich of Earthfax labs in Utah regarding the testing of Humic and Fulvic acids.
One of the points Rich and I agreed on, were quality humic and/or fulvic acids should be high in COOH and OH groups. Since some of my competitors were listed as references on the fax I received, I felt compelled to find out if Rich could prove what The Catalyst Product Group has believed and tried to explain to growers over the past 10 years. Approximately 30 days after Rich received my samples he called me wanting to know what, if anything, I was adding to my products besides Leonardite Shale. My first response was why? He began to tell me that some of the numbers coming back from his tests were way above normal. I explained to him that nothing was added to my products. I discussed some simple steps I took in my manufacturing process and told him I didnít cut any corners. Then I explained some of our storage secrets to help us deliver consistent products to our customers. Rich informed me he would rerun his tests to make sure his tests results were consistent. He did, and they were.
After receiving the test results they didnít mean much to me. Yes, we had COOH and OH groups, but what do we measure them to. If my results were higher, how much? Rich then sent me a list of 10 different products he had tested. Some are pure fulvic acids and some are humic / fulvic acids. There are no names, so we donít know whoís product was tested.
What did the results show? Products 1-3, 8-10 were pure fulvic acids. They had a low of 91 ppm and a high of 322 ppm fulvic acid, with an average of 217.66 ppm of fulvic acid. INTEGRATE tested 325 ppm fulvic acid. Products 4, 5, 7 were humic / fulvic products. They had a low of 703 ppm and a high of 1841 ppm fulvic acid, with an average of 1271.66 ppm fulvic acid. Jenner 8 had 2040 ppm fulvic acid and Jenner 8 II had 2160 ppm fulvic acid.
There were 6 products given on pure fulvic acid for the next 3 tests, total Acidity, COOH, and OH groups. Total Acidity on products 1-6 ranged from a low of 7.25 meq/g to a high of 14.72 meq/g, with an average of 11.06 meq/g. INTEGRATE was 21.8 meq/g. Total COOH groups on products 1-6 ranged from a low of 1.17 meq/g to a high of 10.08 meq/g, with an average of 4.97 meq/g. INTEGRATE was 4.8 meq/g. The total OH groups on products 1-6 ranged from a low of 3.71 meq/g and a high of 8.53 meq/g, with an average of 6.09 meq/g. INTEGRATE was 17 meq/g.
There were only 2 humic / fulvic products tested for Total Acidity, COOH, and OH groups. Total Acidity tested 4.27 meq/g and 3.73 meq/g, for an average of 4.0 meq/g. JENNER 8 tested 4.7 meq/g. JENNER 8 II tested 18.3 meq/g. Total COOH groups tested 3.32 meq/g and 0.32 meq/g, for an average of 1.82 meq/g. JENNER 8 tested 3.2 meq/g. JENNER 8 II tested 2.9 meq/g. The OH groups tested 0.95 meq/g and 3.41 meq/g, for an average of 2.18 meq/g. JENNER 8 tested 1.5 meq/g. JENNER 8 II tested 15.4 meq/g.
There were no humic tests to compare Jenner 8 and Jenner 8 II to. FYI, JENNER 8 contained 16.8 g/L of humic acid. Of that humic content (after the fulvic was separated out), the total Acidity was 2.0 meq/g, the total COOH groups were 1.9 meq/g, and the total OH groups were 0.1 meq/g. JENNER 8 II contained 27.3 g/L of humic acid. Of that humic content (after the fulvic was separated out), the total Acidity was 2 meq/g, the total COOH groups were 1.6 meq/g, and the total OH groups were 0.4 meq/g. NOTE: Humic acids are longer chain carbons, they do not contain as many COOH and OH groups. These two groups are a function of acidity. This is why these numbers are so much lower than pure fulvic acid tests.
