The dosage recommendation to use 1 tablespoon per gallon of the granulated product (24-8-16), which I see on the manufacturer's web site, is rather obscene by my standards.... if you do the calculation this turns out to be 950 ppm N, which is about 20 times higher than the amount I would regularly use to water my garden of mostly succulents. I think the manufacturer just wants to sell more product and that is the reason for the number. I would caution all users against following this recommendation, for the good of the planet if nothing else. If you are going to fertilize regularly (like when you have a rain barrel full of fertilizer water) you need to cut back on the amount you use.
