Potassium sulphate, also known as sulphate of potash (SOP), is a premium quality, water-soluble fertilizer renowned for its high potassium content and essential role in promoting plant growth and development. With a chemical formula of K2SO4, potassium sulphate is a versatile nutrient source suitable for a wide range of crops, making it a preferred choice among farmers, horticulturists, and gardeners worldwide.

Key Features and Benefits:

1. High Potassium Content: Potassium sulphate contains a significant amount of potassium (K), a vital macronutrient essential for various physiological processes in plants. Potassium plays a crucial role in enzyme activation, photosynthesis, osmoregulation, and overall plant health.
2. Sulphur Supplement: In addition to potassium, potassium sulphate provides sulphur (S), another essential nutrient required for plant growth. Sulphur is a constituent of amino acids, proteins, and enzymes, contributing to plant metabolism, chlorophyll synthesis, and nitrogen utilization.
3. Water-Soluble Formula: Potassium sulphate is highly soluble in water, ensuring rapid nutrient uptake by plants and efficient utilization without the risk of nutrient leaching or wastage. Its water-soluble nature makes it suitable for various application methods, including foliar spraying, fertigation, and soil drenching.
4. pH Neutral:potassium-sulphate has a neutral pH, which helps maintain optimal soil pH levels when applied, preventing soil acidity or alkalinity issues that may hinder nutrient availability and plant growth. Its neutral nature makes it compatible with a wide range of soil types and cropping systems.
5. Crop Compatibility: potassium-sulphate is suitable for use on various crops, including fruits, vegetables, grains, ornamentals, and turfgrass. Whether used in commercial agriculture, greenhouse production, or home gardening, potassium sulphate promotes robust root development, improved flowering, fruit set, and overall crop yield and quality.
6. Chloride-Free: Unlike other potassium fertilizers such as potassium chloride (MOP), potassium sulphate is chloride-free, making it an ideal choice for chloride-sensitive crops like tobacco, potatoes, fruits, and certain vegetables. Its chloride-free formulation ensures optimal nutrient uptake and minimizes the risk of chloride-induced crop damage.
7. Long-lasting Effect: Potassium sulphate provides a sustained release of potassium and sulphur, ensuring a steady and prolonged supply of nutrients to plants throughout their growth stages. This prolonged nutrient availability promotes balanced nutrient uptake, reduces nutrient deficiencies, and enhances plant resilience to environmental stressors.

Application Guidelines:

• Soil Application: Incorporate potassium-sulphate into the soil before planting or apply as a top dressing during the growing season. Consult soil test results and crop nutrient requirements for precise application rates.
• Foliar Application: Dissolve potassium sulphate in water and apply as a foliar spray to deliver potassium and sulphur directly to plant foliage. Ensure thorough coverage for maximum absorption.
• Fertigation: Mix potassium-sulphate with irrigation water and apply through drip or sprinkler irrigation systems to deliver nutrients directly to plant roots. Adjust application rates based on crop stage, soil moisture levels, and nutrient requirements.
