Here in the US if one wants to advertise a product as organic it has to meet a LOT of requirements and once these requirements are met one is authorized to use the OMRI label on the product.  Meeting all of these requirements is very expensive to say the least.  There are many products here that are mostly organic.  One product like this is Medina Liquid Plant Food.  It is totally organic except it has manufactured urea instead of natural.  That Tomorite product reminded me of this.  Here in the US a product that has such low NPK numbers (4-3-8) as the Tomorite is one of these products that is almost all natural or organic.  All chemical fertilizers here have high NPK numbers simply because of the Cation Exchange Capacity of the product. This means that there must be much more NPK in the product than the plant can ever possibly uptake because the product cannot adhere to the soil and it quickly leaches away.   As I said, I have never seen this product and only went by what is available here and thought the Tomorite might be similar.
