Fertilizer PPM Calculator

Fertilizer PPM Calculator

The amount of fertilizer to apply to your float bed can easily be calculated with the Fertilizer PPM Calculator. The PPM Calculator can calculate the amount of fertilizer required per 100 gallons of water in your float bed. You simply need to know what your desired nutrient concentration is in “parts per million” ( PPM ) and what the % N is of the type of fertilizer you are planning to use.

Once you have the amount from the PPM Calculator per 100 gallons of water, then use the Water Volume Calculator to calculate how much water you are applying fertilizer to.
