Ammonium Sulfate Fertilizer

Nitrogen is not the only chemical needed for crops to thrive and grow. So in areas that require both nitrogen and sulfur, farmers use ammonium sulfate. This dry granular fertilizer delivers nitrogen entirely from ammonia and is excellent for corn crop fall plow-down and spring pre-plant. Here's how farmers use this fertilizer to support their crops and some key details about this fertilizer type.

• Dry granular
• Made from 24 percent sulfur and 21 percent nitrogen
• With a fairly low nitrogen content compared with other fertilizers, this is not an ideal source of nitrogen unless you need the sulfur contents as well
• Can help bring up the acidity of a farmer's soil compared to using ammonium nitrate due to the nitrification process
• Requires watering crops in alkaline soils to avoid nitrogen loss
• Much like ammonium nitrate, this is not ideal for sloped crops due to the potential for runoff.
