Ammonium Sulphate (AS) is a high-quality nitrogen fertilizer, widely recognized for its fast-acting nature and dual-nutrient content. It’s a source of both nitrogen and sulfur, two essential nutrients for plant growth. The crystalline form of this fertilizer dissolves quickly in water, allowing for rapid nutrient uptake by crops. It’s a popular choice for a variety of crops, particularly those that have high sulfur requirements, such as potatoes, corn, and canola.
