Without knowing the specific product you inquiring about, I will say that many kelp fertilizers in liquid form and the water-soluble kelp powders are processed using potassium hydroxide. Despite this processing using an inorganic compound, many still claim "organic" status.

These products are incredibly effective at giving your plants a boost in potassium levels (and increasing yields) but run a real risk of throwing off your soil's microbiome.

Kelp Meal is much better for the overall health of your soil, but will need some time to break down in order to provide your plants it's benefits. It's also much cheaper to purchase.
