Ammonium sulfate granules (steel grade), with a nitrogen content exceeding 20.5% and a sulfur content exceeding 23.5%, have become a key fertilizer for increasing yields in modern agriculture. This article, starting from granule uniformity, rapid dissolution characteristics, and high absorption rate, and combining international quality standards and global application cases, systematically analyzes its scientific mechanism for promoting crop growth, helping farmers achieve efficient planting and increased profits.
A comparative experiment illustration of the rapid dissolution of ammonium sulfate granules in water shows the difference in dissolution speed between steel grade granules and ordinary powder.
How does ammonium sulfate granules (steel grade) scientifically improve crop yields? In-depth analysis by agricultural experts.
In modern agriculture, the choice of fertilizer directly affects crop growth efficiency and final yield. Ammonium sulfate granules (steel grade) produced by Yunnan Yingfu, with its high nitrogen content exceeding 20.5% and sulfur content exceeding 23.5%, are becoming a new choice for growers worldwide to optimize their fertilization programs.
Why are high nitrogen and high sulfur key?
Nitrogen is a core component in the synthesis of plant proteins and chlorophyll, while sulfur participates in amino acid formation and enhances disease resistance. Studies have shown that the rational application of sulfur-containing nitrogen fertilizers can increase wheat yield by 12%-18% and corn yield by 10%-15%, with particularly significant effects in sulfur-deficient soil areas (Data source: FAO 2023 Global Nutrient Management Report). Yunnan Yingfu ammonium sulfate granules utilize industrial-grade refining technology to ensure that each granule contains ≥20.5% N and ≥23.5% S, far exceeding the nutrient density of ordinary urea or compound fertilizers.
Uniform granules + rapid dissolution = high absorption rate. Traditional powdered ammonium sulfate is prone to clumping, difficult to spread, and slow to absorb. Yunnan Yingfu, through proprietary granulation technology, controls the granule diameter to between 2-4 mm, facilitating mechanized fertilization and achieving the characteristic of “instant dissolution in water”—field trials show that its dissolution rate is about 3 times faster than ordinary powders, effectively reducing nutrient loss and improving root utilization.
A comparative experiment illustrating the rapid dissolution of ammonium sulfate granules in water demonstrates the difference in dissolution speed between high-grade granules and ordinary powder. International Certification Backing, Quality You Can See: The product has passed ISO 9001 quality management system certification and EU REACH compliance testing, and meets US NPK standards (ASTM D1807). It is sold in over 40 countries and regions worldwide. Farmers in the Mekong Delta of Vietnam report: “After using Yunnan Yingfu ammonium sulfate granules, the number of rice tillers increased significantly, resulting in an average increase of approximately 150 kg per mu (unit of land area) in yield.”
Competitive Product Comparison: Why is it More Trustworthy?
Specifications: Yunnan Yingfu Steel-Grade Ammonium Sulfate vs. Common Ammonium Sulfate
Nitrogen Content (%) ≥20.5 16–19
Dissolution Time (minutes) ≤3 8–15
Particle Uniformity ±0.5mm ±2mm
Recommended Application Scenarios: Suitable for both field crops and greenhouses.
Whether for field crops like soybeans and corn, or horticultural fruits and vegetables like tomatoes and strawberries, Yunnan Yingfu ammonium sulfate granules allow for dosage adjustments based on crop growth stages: 10-15 kg per acre during the seedling stage, and an additional 10 kg during the flowering stage, significantly improving photosynthetic efficiency and fruit quality.
Farmers using ammonium sulfate granules as a base fertilizer before sowing demonstrate the effect of even granular fertilizer application.
