Potassium Sulphate SOP

Potassium Sulphate SOP
Potassium Sulphate (SOP), chemically known as K₂SO₄, is a premium, chloride-free potassium fertilizer containing 50-52% K₂O and 17-18% sulfur. It is the preferred potassium source for high-value, chloride-sensitive crops due to its ability to significantly enhance crop quality without the risk of chloride toxicity. SOP improves fruit size, sugar content, color, and shelf life while also providing essential sulfur for protein synthesis. Its excellent water solubility makes it ideal for fertigation and foliar application. SOP is indispensable in modern agriculture for maximizing the yield and marketability of cash crops, fruits, and vegetables.

Product Details

1.Key Features
Chloride-Free: Contains virtually no chloride (Cl⁻ < 2.5%), making it safe for chloride-sensitive crops.
High Nutrient Value: Provides a high concentration of potassium (K₂O) along with readily available sulfur (S).
Excellent Solubility: Fully water-soluble, ensuring quick nutrient availability and suitability for all fertigation systems.
Low Salt Index: Has a lower salt index compared to Muriate of Potash (MOP), reducing the risk of salt stress and root damage, especially in saline soils or protected cultivation.

Quality Enhancer: Directly contributes to superior crop quality attributes such as brix (sugar content), color, and storability.

2.Primary Functions and Benefits

FunctionBenefit to PlantsAgronomic Advantage
Potassium SupplyRegulates water relations, enzyme activation, and sugar transport.Enhances fruit size, weight, and firmness; improves drought and disease resistance.
Sulfur SupplyEssential for the synthesis of amino acids (cysteine, methionine) and proteins.Corrects sulfur deficiency, improves nitrogen use efficiency, and promotes healthy plant growth.
Quality ImprovementImproves sugar accumulation, color development, and oil content in seeds.Increases the market value of produce such as fruits, vegetables, and oilseeds.
Chloride AvoidancePrevents chloride toxicity, which can cause leaf burn and reduce yield and quality in sensitive crops.Protects high-value crops from damage, ensuring optimal performance and profitability.

3.Target Crops and Application Scenarios
Chloride-Sensitive Crops: Tobacco, potatoes, grapes, strawberries, citrus, avocados, and some beans - These crops are highly sensitive to chloride, and SOP is the standard potassium fertilizer for them.
High-Value Fruits and Vegetables: Tomatoes, peppers, melons, onions, garlic - Used to improve flavor, sweetness, and appearance.
Oilseed Crops: Canola, soybeans, sunflowers - Sulfur is crucial for oil synthesis in these crops.
Greenhouse and Hydroponic Systems: Its low salt index and high solubility make it ideal for controlled environment agriculture.
Saline and Sodic Soils: Preferred over MOP in areas with existing salinity issues to avoid exacerbating the problem.
2.4 Application Guidelines (General)
Fertigation (Recommended):
Dilution: Dissolve 5-10 kg of SOP in 1000 liters of water.
Application Rate: Apply 5-15 kg per hectare per application during critical growth stages such as fruit development and bulking.
Foliar Spray:
      Dilution: Dissolve 2-3 kg in 1000 liters of water.
      Spray: Apply evenly on leaves, focusing on the underside. Best done during cool, humid conditions for maximum absorption.

      Soil Application: Can be broadcast or band-applied as a basal dose. Rates vary from 100-300 kg per hectare depending on crop needs and soil test results.


Note: Potassium Sulphate (SOP) is the premium choice for farmers and growers who prioritize crop quality and need to avoid chloride-related issues. While it is more expensive than MOP, the significant improvements in crop quality and yield for sensitive crops often justify the additional cost. It is an essential component of high-value agricultural production systems.
