You use 25 pounds of a 15-11-29 fertilizer mix in a 30 gallon concentrate tank, and then use a 1:100 dilution in your injector. How much nitrogen are your plants getting (in ppm)?


Use the following formula:

ppm = (% fertilizer) x (lb added to tank) x (16 oz per lb) x (.75) x (100/gal of concentrate) x (1/ratio of injector)

150ppm nitrogen

ppm = (% fertilizer) x (lb added to tank) x (16 oz per lb) x (.75) x (100/gal of concentrate) x (1/ratio of injector)

PPM = (15) X (25) X (16) X (0.75) X (100/30) X (1/100)
