Kingenta® NPK fertilizer (SOP-based)

We select high-quality sulfur-based raw materials such as potassium sulfate to ensure that they are completely free of chloride ions that are harmful to crops, thereby avoiding quality degradation and physiological disorders. Applying a certain amount of phosphorus and potassium fertilizer before crop planting or seed germination can promote root growth and development, ideal for fruits, vegetables, and field crops. Bulk supply, OEM packaging, and global export available.


    Product Description

    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 & Yield Enhancement
    With scientifically proportioned nitrogen, phosphorus, potassium and rich trace elements, it protects 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

    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 15–20%.
