Crystal Ammonium Sulphate 21-0-0 represents the refined, highly soluble form of traditional ammonium sulfate, offering superior performance characteristics for precision agriculture and specialized applications. Zhongsheng Yunhua Co., Ltd. manufactures premium-grade crystal ammonium sulphate that meets the exacting standards of modern agricultural and industrial users worldwide.
Crystal ammonium sulphate features a distinctive crystalline structure that provides exceptional solubility and rapid nutrient release. This physical form differentiates it from granular or prilled versions through:
Instant Dissolution Characteristics
The crystalline form dissolves completely within seconds upon contact with water, creating a clear solution ideal for fertigation systems and foliar applications without risking nozzle clogging or sediment formation.
Enhanced Nutrient Availability
With 21% nitrogen content exclusively in the ammonium form and 24% sulfur present as sulphate, this fertilizer provides immediately available nutrients that plants can rapidly utilize without requiring further soil conversion.
Superior Purity Standards
The crystallization process eliminates impurities that may be present in other forms, resulting in a product with minimal contaminants suitable for sensitive applications and high-value crops.
Zhongsheng Yunhua's Crystal Ammonium Sulphate 21-0-0 exceeds industry standards:
Nitrogen Content: 21% minimum (Ammoniacal form)
Sulfur Content: 24% minimum (Sulphate form)
Solubility: 75g/100ml at 20°C
Moisture Content: <0.2%
Appearance: White crystalline particles
Heavy Metals: <10ppm total
Precision Agriculture Systems
The complete solubility and rapid dissolution make crystal ammonium sulphate ideal for:
Automated fertigation systems
Hydroponic production
Greenhouse nutrient solutions
Foliar feeding programs
Industrial Applications
Beyond agriculture, this product serves critical functions in:
Water treatment processes
Chemical manufacturing
Pharmaceutical preparations
Laboratory analytical applications
Soil Amendment Properties
The ammonium fraction provides acidifying effects beneficial for alkaline soils, while the sulphate form offers plant-available sulfur that enhances nitrogen utilization efficiency and protein synthesis.
Versus Granular Ammonium Sulphate
Immediate solubility versus gradual breakdown
Uniform application in liquid systems
No residue in irrigation equipment
Faster plant response
Versus Urea-Based Fertilizers
No nitrogen volatilization losses
Immediate nutrient availability
Additional sulfur content
Acidifying effect on alkaline soils
Versus Compound Fertilizers
Higher nutrient concentration
Customizable blending capability
Predictable nutrient release
Cost-effective nitrogen source
Fertigation Systems
Use at concentrations of 0.5-2.0% in irrigation water, ensuring compatibility with other nutrients. The crystalline form prevents precipitation issues common with less soluble fertilizers.
Foliar Applications
Apply as 1-3% solutions with appropriate surfactants for optimal leaf coverage and nutrient absorption. The high purity minimizes leaf burn potential.
Hydroponic Nutrient Solutions
Provides both nitrogen and sulfur in readily available forms, maintaining electrical conductivity within optimal ranges for plant growth.
What is the difference between crystal and granular ammonium sulphate?
Crystal ammonium sulphate features instant dissolution properties and higher purity, making it suitable for liquid applications, while granular forms are designed for dry broadcast applications with slower release characteristics.
How does crystal ammonium sulphate affect soil pH?
The ammonium component undergoes nitrification, releasing hydrogen ions that gradually lower soil pH, making it particularly beneficial for alkaline soils but requiring monitoring in already acidic conditions.
Can crystal ammonium sulphate be blended with other fertilizers?
Yes, it is compatible with most water-soluble fertilizers except those containing calcium or phosphorus, which may form insoluble precipitates.
What crops benefit most from crystal ammonium sulphate?
Crops with high sulfur requirements such as cruciferous vegetables, legumes, and cereals show particularly positive responses. It is also valuable for crops requiring quick nitrogen correction.
What storage conditions are recommended?
Store in moisture-proof containers in cool, dry conditions. Although less hygroscopic than some fertilizers, proper storage prevents caking and maintains flowability.
