Select SOP 0-0-50+17.5 S is our water-soluble potassium sulphate fertilizer, especially formulated for hydroponics and fertigation. It’s the perfect blend if your crops require plenty of potassium and Sulphur, helping to prevent potential deficiencies. It’s nitrogen-free, which is especially handy when you’re at the fruit ripening stage. It’s also low in sodium, making it ideal with saline soil or with crops which are salt-sensitive. Plus, if your soil is alkaline, it can lower the rootzone’s pH, improving phosphor and micronutrient uptake. It comes in very fine particles, making it quick and easy to dissolve.
