This liquid fertilizer is derived from 100% Ascophyllum nodosum kelp, hand harvested and extracted through a unique, 40-year-old proprietary process. Many of the most beneficial and active ingredients of kelp are damaged during most extraction processes. Our kelp is extracted using the least destructive process available and is unique in that it does not include dissolving the kelp in a chemical solution. Long recognized by farmers for its wide range of plant nutrients, biological growth stimulants, and soil conditioning benefits, liquid kelp is an ideal addition for any growing system. Kelp is proven to be a highly potent microbial food source for beneficial soil organisms and a great input for compost extracts.
