CDFA Approves use of HPTA Test Method Seal
In continued effort to roll out the HPTA test method seal, HPTA President met with CDFA (California Department of Food & Agriculture) requesting seal use on fertilizer packaging in California.
All products sold in California bearing the HPTA seal must pass both HPTA and CDFA humic acid test. For example: if a products tests 6% humic acid using CDFA method and 5% humic acid using HPTA endorsed method, then the label must indicate 5% humic acid as it relates to the HPTA method. The lowest of the two test methods must be used on the label.
The specific guidelines are outlined in the January 16th letter from Dr. Dale Woods, CDFA Environmental Program Manager. This decision applies only to the humic acid and does not include fulvic acid (yet). This is huge step forward to bringing clarity to consumers and standardization to a growing and dynamic humic industry.
