This is mainly because the world soil's average nitrogen fertilizer is not high, nitrogen is not easy to accumulate in the soil, and modern intensive agriculture has promoted the soil organic matter and nitrogen excessive loss, in most conditions, unit nitrogen production is higher than phosphorus, potassium nutrients.
