Which of the following fertilizers has a high nitrogen content ?
Show answer Hide answer
Answer: A. Urea
Explanation
Urea is a widely used solid nitrogen fertilizer containing high nutrient percentages. Its chemical composition delivers substantial nitrogen directly to growing crops. Agronomists rely on urea for cost-effective agricultural crop fertilization. Nitrogen is an essential macronutrient required for plant vegetative growth. Urea manufacturing involves combining synthetic ammonia and carbon dioxide compounds. Proper fertilizer application maximizes crop yields while minimizing environmental runoff.
Global agriculture depends on synthetic fertilizers to sustain high food production levels. Farmers monitor soil nutrient tests to determine optimal fertilizer application rates. Subsidies on nitrogen fertilizers often form a major part of agricultural state budgets. Ammonium nitrate contains nitrogen but features a lower percentage than pure urea. Calcium nitrate provides both calcium and nitrogen with lower total nitrogen concentration. Since urea is correct, selecting none of these options is incorrect.
