Product description

A sulfate-based compound fertilizer built around chloride-free potassium sulfate.

Chloride-free potassium sulfate core

This sulfate-based compound fertilizer is specially developed for fruits, vegetables, tobacco, potatoes and other crops that are sensitive to chloride. 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

Balanced nitrogen, phosphorus, potassium and trace elements protect the physiological functions of chloride-sensitive crops. 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 cropping systems much more sustainable over the long term.

Characteristics of sulfate-based compound fertilizer

Five reasons growers of chloride-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.
