What questions should we ask a humic salesman about his product?
What is the source material, how is it extracted, on the label does it break things out in very specific detail or does it just kind of lump stuff under humic substance? Does it have any registration with the fertilizer boards or is it just a soil amendment product? What is a guaranteed analysis, if it's liquid does it stay in suspension very well, what's the pH of the product?
Soil and test plant tissue test from farmers in the area that have been using the product compared to the untreated.
Any change to fertility programs?
How are they going to recommend using it? |
