Comprehensive quality & yield enhancement: Scientifically proportioned nitrogen, phosphorus, potassium and rich trace elements protect chlorine-free crops from the source while sulfur improves crop quality and overall yield.
Sustainable ecological planting: Designed to alleviate soil salt damage, promoting healthier root zones and making ecological planting more sustainable over the long term.
Product description
A sulfur-based compound fertilizer built around chloride-free potassium sulfate.
Chloride-free potassium sulfate core
This sulfur-based compound fertilizer is specially developed for fruits, vegetables, tobacco, potatoes and other crops that are sensitive to chlorine. It uses potassium sulfate as its core potassium source to completely avoid the harm of chloride ions and ensure the healthy growth of crops.
Comprehensive quality and yield enhancement
Scientifically proportioned nitrogen, phosphorus, potassium and rich trace elements protect the physiological functions of chlorine-free crops from the source. Sulfur improves crop quality, while balanced nutrition directly increases overall yield.
Sustainable ecological planting
Designed to alleviate soil salt damage, promoting healthier root zones and making ecological planting much more sustainable over the long term.
Characteristics of sulfur-based compound fertilizer
Five reasons growers of chlorine-sensitive crops choose SOP-based nutrition.
Chloride-free safety
Zero chloride ions protect sensitive root systems and prevent toxicity, ensuring healthy growth and higher survival rates.
Enhanced crop quality
Sulfur boosts protein synthesis, enzyme activity, and sugar accumulation, resulting in sweeter fruits, vibrant colors, denser tubers, and improved marketability.
Balanced nutrition
NPK ratios are tailored for each crop stage, with added magnesium, zinc, and boron for comprehensive nourishment.
Soil remediation
Sulfate compounds reduce soil salinity, lower pH in alkaline soils, and improve structure, enhancing water retention and microbial activity.
Eco-efficiency
Controlled-release technology minimizes leaching, increasing nutrient uptake by 30% and raising yields by 15 to 20%.

Key application advantages
Why SOP-based potassium performs where chloride-sensitive crops are grown.
Low chloride content
Potassium is derived from SOP (potassium sulfate), keeping chloride levels minimal across the whole formula range.
No burning risk
Low salt index formulation avoids burning risk to sensitive roots or foliage during application.
Reduced water stress
Supports crops through reduced water stress during critical growth stages.
Potassium fulvic acid added
Contains added potassium fulvic acid for enhanced nutrient uptake and utilization.
Complete formula range
A complete formula range is available to suit varying crop demands and growth stages.
