Ammonium Sulphate

Sulfur is one of the world's oldest remedies for gardens and human ailments. It occurs naturally as a pure element in the form of a yellow powder and as crystals. Sulfur is a product of volcanic emissions and ancient societies mined sulfur around volcanoes. In modern times, most sulfur production is a by-product of crude oil and gas processing. Sulfur readily forms compounds such as pyrite (iron sulfide) and gypsum (calcium sulfate). It is an essential element, as all living cells contain sulfur.

Our key product, also known as the “fourth nutrient”, is ammonium sulfate. Ammonium sulfate provides numerous crop benefits across a variety of crops from food products to turf and foliage, and is a necessary component to healthy crop development. Crop varieties are illustrated below:

Specific benefits of ammonium sulfate include:
  • Increasing drought tolerance through enhancing root development
  • Helping to maintain a dark green color by promoting chlorophyll production
  • Promoting nodule formation on legumes
  • Aiding in the conversion of nitrates into proteins
  • Stimulating seed production and early maturity
  • Being an integral part of certain amino acids
  • Assisting in the breakdown of organic matter
  • Improving soil structure and increasing water infiltration

While many companies produce this fertilizer compound, few produce it as a premium granular product like we do. Other producers make ammonium sulfate as a by-product, which creates a more yellow/brown substance that is less consistent in size and less uniform in hardness. This type of ammonium sulfate makes it harder to mix and distribute the product to the field, making it less likely to be absorbed. In contrast, PCI’s ammonium sulfate is very white in appearance, uniform in size and hardness, and contains an anti-caking agent for easy storage. Our ammonium sulfate is designed for easy bulk blending, direct application distribution, and plant absorption. The picture below clearly demonstrates the difference between PCI premium ammonium sulfate and that of other producers.
