The label lists each by weight %. It has 5.0% nitrogen, which means 50 grams of nitrogen dissolved in 1 liter (=1,000 grams) of solution.
If you want 10 ppm nitrogen (= 10 mg /liter) in 100 liters, you need to add a total of 1,000 mg of nitrogen.
Using your fertilizer, you would need to add 0.02 liters ( = 20 ml ) to get 1,000 mg of nitrogen.
Somebody, please double-check my calculations.
