According to Dr. Robert E. Pettit, “The size of fulvic acids (FA) are smaller than humic acids (HA) and they have an oxygen content twice that of humic acids (HA). Because of their smaller size of molecules FA’s can readily enter plant roots, stems, and leaves. As they enter these plant parts they carry trace minerals from plant surfaces into plant tissues. Fulvic acids (FAs) are key ingredients of high quality foliar fertilizers.”1
The secret power of FA is shown below in a test on cut flowers. In the test, half of the flowers were put in plain water, while the other half was put in fulvic acid. Pictures were taken each day and after 2 weeks the results were amazing. Imagine how using FA on your crop will increase plant health!
