Ammonium sulfate is a necessary component to healthy crop development. Crop varieties that benefit from AS include:
(Click crop to view research and sulfur required by crop)
Increases drought tolerance by promoting root development
Assists in the breakdown of organic matter
Stimulates seed production and early maturity
Aids in the conversion of nitrate into protein
Integral part of certain amino acids
Helps plants maintain dark green color by promoting chlorophyll production
Promotes nodule formation on legumes
Increases water filtration
Improves soil structure
Ammonium Sulfate fertilizer provides two essential plant nutrients: nitrogen and sulfur. For regions in the United States with sulfur-deficient soil, supplementing with AS lowers a crop’s vulnerability to nitrogen loss from leaching, volatilization, and denitrification. Ammonium sulfate also helps crops maintain a higher nutrient efficiency (including nitrogen, potash, phosphates, and micronutrients), and contains sulfur that is readily available for plant absorption.
Sulfate sulfur from AS fertilizer is the only sulfur supplement that is 100% water soluble and available for immediate plant root absorption. Other sulfur products only supply elemental sulfur or an elemental/sulfate combination, which needs a conversion period.
