I was wondering if I mix a 0-7-0 bat guano, and a 2-4-6 sea bird guano is the total NKP of the mix 2-11-6?

I was told it does but when I tryed organic I wasn't getting enough of something and I had to switch to chemical because everything is to low in organic and takes so much time to respond to sick plants, if your new like me its easyer to go with a chemical ferts!

The NPK values are the percentage of the product you are using that is nitrogen, phosphorus and potassium. So if you had a product that was 2-4-6 then it would be only 2% nitrogen meaning if you added that to a product which contained no nitrogen then percentage of the new mix couldn't be 2% as the nitrogen levels would be diluted from the product which contained no nitrogen...The same principles would apply to the phosphorus and potassium values as well.

That makes sense, Plus if the amount isn't the same that would throw it off to, wouldn't it?
