The nitrogen percentage found within ammonium sulfate fertilizer is___________________?
Show answer Hide answer
Answer: D. 21
Explanation
Ammonium sulfate fertilizer contains a specific guaranteed percentage of elemental nitrogen. Laboratory analysis confirms that this compound provides approximately 21 percent nitrogen. It also supplies essential sulfur nutrients required for healthy agricultural crop growth. Fertilizer nutrient content is expressed as a guaranteed minimum percentage by weight. Ammonium sulfate is a crystalline salt used widely in global agricultural soil management. The presence of ammonium ions allows for rapid uptake by plant root systems.
Farmers apply ammonium sulfate to correct nitrogen and sulfur deficiencies in alkaline soils. The fertilizer has an acidifying effect that benefits specific crops grown in high pH regions. Calculating fertilizer application rates requires knowing the exact elemental nutrient percentages. A 23 percent nitrogen value overestimates the actual composition of ammonium sulfate. A 35 percent nitrogen level corresponds to different high analysis fertilizers like ammonium nitrate. A 45 percent nitrogen concentration describes urea rather than ammonium sulfate fertilizer.
