What is the typical nitrogen content in urea fertilizer?

  1. 46%

  2. 30%

  3. 20%

  4. 16%

The correct answer is: 46%

Urea fertilizer is known for its high nitrogen content, typically around 46%. This makes it one of the most concentrated sources of nitrogen available for agricultural use. Nitrogen is a crucial macronutrient for plant growth, as it plays a vital role in the development of chlorophyll and amino acids, contributing to overall plant health and productivity. The high nitrogen percentage in urea allows farmers to apply less product while still meeting the nitrogen needs of their crops, which can lead to both economic and environmental benefits. The other options mentioned represent lower nitrogen contents found in different fertilizers or formulations, making them less effective as nitrogen sources compared to urea.
