Kelp use in vegetable gardening
How helpful is kelp in vegetable gardening? Why is it so expensive? Do the benefits justify the cost?
Boulder County Colorado
Kelp is one of many organic fertizers. It is valued for micronutrients, trace minerals, amino acids, and vitamins plus growwth hormones that stimulate plant cell division. You may wish to read the information on this link http://www.cmg.colostate.edu/gardennotes/234.pdf
The costs are probably associated with collection, processing, supply and demand, world economic factors, etc.
You may be able to buy kelp at an animal feed store for a better price. Also try contacting Harlequin Gardens in Boulder for an answer to your question about whether the benefits justify the cost.
