Q. What was the recent NPK ratio in Punjab?
Answer:
23.5:5.4:1
Notes: Punjab's NPK ratio in 2021-22 was 23.5:5.4:1, far exceeding India's average of 7.7:3.1:1. The ideal NPK ratio is 4:2:1. Excess nitrogen application, largely due to urea subsidy after the Green Revolution, has caused serious nutrient imbalance in Punjab soils.
