Low molecular weight Fulvic acids range in molecular weight from around 10,000 to 100,000 daltons. The lower the weight of the fulvic acid molecule, the more active or better at chelating and delivering nutrients it is. Many fulvic acid products are likely to comprise a wide range of molecular weights within the 10,000 to 100,000 dalton range. This is because the extraction process is not usually selective in isolating only the lower weight molecules. AFT10 is different because the extraction process is different; rather than being mined, it is gathered via a selective process that isolates molecules of the lowest weight and highest cation exchange capacity which enables it to bind with and transport many times its own weight in trace minerals and nutrients. In addition, AFT10 is complexed to enhance its effectiveness. Having a low molecular weight fulvic is one of the product's advantages and why turf management professionals are reporting excellent root improvement even under trying conditions such as profile saturation, disease, pest infestations such as eelworms/nematodes, compaction, saline irrigation use and low light conditions of winter. The product is effective at all soil pH ranges. Alastair Johnston is the director of Fulvic Link, Pty, www.fulviclink.com l Typical rootzones before (above) and after (right) treatment
