CHEMICAL FERTILIZER vs. ORGANIC FERTILIZER:
On a molecular level, the nutrients are identical, so I don't understand how organic fertilizers have gotten such publicity. It matters not where the source of the nutrients came from if the molecule is the same to the plant. Having said that, the chemical fertilizer is more concentrated and lasts longer so repeat applications are not necessary at a lower cost. Organic fertilizers cost more, you get less and they have to be reapplied.
However, if you still are not convinced of the logic of using the chemical fertilizer, we sell the best organic fertilizer that we can find. It is made up of crushed bones, dried blood, crushed fish, and langbeinite. Langbeinite is a potassium magnesium sulfate mineral.
