A farmer cultivates 5 hectares of sugarcane. The recommended doses are 150 kg/ha of nitrogen, 80 kg/ha of phosphorous, and 120 kg/ha of potassium. What is the total amount of fertilizer (sum of N, P, and K) required?

Step-by-step solution

1. Multiply nitrogen dose by area: $150\times 5=750$ kg.
2. Multiply phosphorous dose by area: $80\times 5=400$ kg.
3. Multiply potassium dose by area: $120\times 5=600$ kg.
4. Add the three amounts: $750+400+600=1750$ kg.
