Potassium Sulphate

Product Name: Potassium Sulphate

Purity Grade: Analytical Grade

CAS Number: 7778-80-5

Size: 1 millimetre in average

Appearance: Offwhite powder

Other Features: Hydrophilic

Potassium sulphate, also known as sulphate of potash or SOP, is a highly soluble and crystalline salt that contains two essential nutrients for plant growth: potassium (K) and sulphur (S). This fertilizer is produced through a chemical reaction between potassium chloride and sulphuric acid. The resulting white crystals are then ground into a fine powder, making it easy to handle and apply.

The Importance of Potassium and Sulphur for Plants

1. Potassium: Potassium is one of the three primary macronutrients required by plants, along with nitrogen (N) and phosphorus (P). It is essential for various physiological processes, including photosynthesis, protein synthesis, enzyme activation, and water regulation. Potassium also improves plant resistance to diseases and pests, enhances root development, and promotes overall crop quality.
2. Sulphur: Sulphur is a secondary macronutrient that is often overlooked, but it plays a crucial role in plant metabolism. It is a key component of amino acids, proteins, and vitamins. Sulphur deficiency can lead to stunted growth, reduced yield, and decreased quality of crops.

Benefits of Potassium Sulphate

1. High Nutrient Content: Potassium sulphate contains around 50% potassium (K2O) and 17% sulphur (S). This high nutrient content ensures that plants receive an adequate supply of potassium and sulphur, preventing deficiencies and promoting optimal growth.
2. Enhanced Crop Yields: The adequate supply of potassium and sulphur provided by potassium sulphate can result in increased crop yields. The balanced nutrient ratio in this fertilizer supports healthy plant development, improves fruit and vegetable quality, and enhances overall productivity.
3. Improved Nutrient Uptake Efficiency: Potassium sulphate has a high solubility, allowing the nutrients to be readily available for plant uptake. This enhances nutrient uptake efficiency, reducing the risk of nutrient leaching and ensuring that plants can access the necessary nutrients when needed.
4. Suitable for Various Crops: Potassium sulphate is suitable for a wide range of crops, including fruits, vegetables, grains, and ornamental plants. Its versatility makes it a popular choice for both small-scale and large-scale farming operations.
5. Better Soil Quality: Continuous use of potassium sulphate can improve soil quality over time. It helps to maintain the appropriate pH level, enhances soil structure, improves nutrient holding capacity, and promotes beneficial microbial activity.

How to Properly Apply Potassium Sulphate

1. Soil Application: Potassium sulphate can be applied directly to the soil through broadcasting or banding methods. It is recommended to conduct a soil test beforehand to determine the appropriate application rate. The fertilizer can be incorporated into the soil before planting or top-dressed during the growing season.
2. Foliar Application: In some cases, foliar application may be necessary to address immediate nutrient deficiencies. Potassium sulphate can be dissolved in water and sprayed directly onto the leaves, allowing for rapid nutrient absorption. However, it is important to follow the recommended application rates to avoid leaf burn or other issues.
3. Timing and Frequency: The timing and frequency of potassium sulphate application depend on the specific crop and its growth stage. It is generally recommended to split the application to ensure a continuous supply of nutrients throughout the growing season. Consult crop-specific guidelines or seek advice from agricultural experts for optimal results.
