Re: NPK ratio- Why nobody agrees on this?
Any fertilizer where the 3 numbers are the same are the same proportions. 8-8-8 is half the quantity of nutrients as 16-16-16, so you have to apply twice as much. There is a magic formula, which I don't remember, but something like 9-3-27. Bought the ingredients and mixed the formula and saw no difference from 15-15-15, which is a whole lot cheaper. So, more money for no better results doesn't go far in my garden.
