Ammonium Sulfate Fertilizer Grade, commonly referred to as AS, is a premium nitrogen fertilizer designed to provide crops with a balanced supply of nitrogen ($N$) and essential sulfur ($S$). With a total nitrogen content of $\ge 20.5\%$ and sulfur content of $\ge 21\%$, it is an exceptionally stable and fast-acting fertilizer. It is particularly effective in alkaline soils, where it helps to balance soil $pH$ while delivering nutrients that are immediately available for plant uptake.Compared to standard urea, Ammonium Sulfate is less prone to nitrogen volatilization, making it a reliable choice for top-dressing and base fertilization. It is a foundational component in the production of compound fertilizer and blended fertilizer (BB fertilizer). Extensive research on crops like maize has shown that applying Ammonium Sulfate effectively increases the soil's alkali-hydrolyzable nitrogen content, leading to significantly higher yields and improved crop quality.Key Performance BenefitsDual-Nutrient Supply: Simultaneously replenishes nitrogen and sulfur, essential for protein synthesis and enzyme activity.Superior Stability: Excellent physical properties with low moisture absorption, ensuring it remains free-flowing and easy to store.Alkaline Soil Specialist: Ideal for use in high $pH$ soils, helping to acidify the root zone for better micronutrient availability.Fast-Acting Nitrogen: Provides ammonium nitrogen that is readily absorbed by plants for a quick growth "boost."Wide Crop Compatibility: Highly effective for field crops (maize, wheat, cotton) and economic crops (citrus, tea, soybeans).Common ApplicationsField Crops: Enhances the vegetative growth of corn and wheat, ensuring robust stalk development.Cash Crops: Improves the flavor and quality of tea leaves and the oil content in soybeans.Industrial Blending: Used as a high-quality nitrogen source for manufacturing NPK compound fertilizers and blended fertilizers.Horticulture: Provides a steady nitrogen release for fruit trees and ornamental plants.
