A 50 kg bag of N-P-K fertilizer with an analysis of 3.1.3 (42) is broadcasted over an area of 12 ha. Calculate total Nitrogen mass in the bag, in kg.
Question
Solution 1
The analysis of 3.1.3 (42) on the fertilizer bag indicates the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) in the fertilizer. The first number (3) represents the percentage of Nitrogen.
Step 1: Convert the percentage of Nitrogen to a decimal by dividing by 100. So, 3/100 = 0.03.
