I am guessing this wasnt on your study material....:hammerhead:

Assumptions:
We only care about the N value
24-x-x is your fertilizer analysis
50 lb bag size

That means that 24% of your 50 lb bag is N
or
12 lbs of N in the bag

Depending on how many lbs of N you want to apply will determine how to calibrate your machine and how far your 50 lb bag will go.

if you want 1 lb of N per k your 50 lb bag will cover 12k
if you want 1/2 lb N per k your 50 lb bag will cover 24k

Make sense?

Now take that 50lb bag and divide that by the 12k it will cover and that will tell you that you should be applying 4.16lbs of product per K so when you callibrate you know how much per K you should be using.
