Why does good organic fertilizer cost more than inorganic types?
It’s more difficult to make. For example, the pelleted fish fertilizer contains ground fish scraps, fish bone meal, feather meal, blood meal, alfalfa meal, and sulfate of potash. Blending all of these different ingredients together isn’t easy. However, when you consider that gradual-release organic fertilizers mostly end up being used by plants, while less expensive chemical fertilizers mostly evaporate or wash out of the root zone, then organics make better economic sense.
