Question

Calculate the quantity of fertilizer required for making a 100 ppm solution of 20-10-20 in a 500 litre tank?

• A. 150 g
• B. 250 g
• C. 350 g
• D. 00 g

Hint:

To quickly find the fertilizer amount in grams for a given ppm of N:
\[ \text{Fertilizer (g)} = \frac{\text{ppm} \times \text{Volume (L)}}{\% \text{ Nutrient} \times 10} \] Here, \[ \frac{100 \times 500}{20 \times 10} = \frac{50000}{200} = 250 \text{ g} \]

Answer 1

The Correct Option is B
