Solution(By Examveda Team)

At constant prices of fertilizer and crops, net returns can be increased by efficient fertilizer use.
Fertilizers provide crops with nutrients like potassium, phosphorus and nitrogen, which allows crops to grow bigger, faster and produce more food. This not only offers important benefits for farmer incomes and food security but also produces environmental benefits by reducing our demands for farmland.
