It seems that we are always searching for the
right measure of something. We always need to convert from the information
on a given label to a measuring device that we have on the shelf. Well,
below is a listing of the most common conversions. As always, more of
something is not generally better. Mix all chemicals according to the
manufacturers recommendation.

To
determine parts per million(ppm) of an element in a fertilizer, simply
multiply the percent of that element by 75. The answer will be the ppm
of the element per ounce of the fertilizer in 100 gallons of water. |

Example: 20-10-20 contains 20% Nitrogen. 20% multiplied by 75 is 15,
which is the ppm of Nitrogen in one ounce of 20-10-20 per 100 gallons
of water. Therefore, if 200ppm N is desired, divide 200 by 15 = 13.3
oz of 20-10-20 are required to produce a 200 ppm N solution in 100
gals of water. |
