SOP Potash (Sulphate of Potash) 0-0-50

Chloride-free potassium & sulphur | Granular (SGN 200–300) & fully soluble for sensitive crops

Global agricultural operations producing premium, chloride-sensitive cash crops cannot substitute muriate of potash due to salt toxicity risks. CBIL brokers SOP from European, North African and South American production centres: Germany and Belgium (K+S, Tessenderlo Kerley via Antwerp and Rotterdam), Egypt, Jordan (APC downstream), Chile, and Australia. Supply moves in 50 kg PP bags with inner polyethylene liners, 1 MT jumbo bags (FIBCs), 25 kg bags for water-soluble grades, and bulk vessel parcels on FOB, CFR, and CIF terms, verified by independent load-port inspection from SGS or Intertek.

Sulphate of potash is the premier dual-nutrient potassium and sulphur fertilizer: potassium oxide (K₂O) 50.0–52.0% minimum, sulphur (S) 17.5–18.0% in readily bioavailable sulphate (SO₄) form, moisture ≤ 0.5%, and chloride capped at ≤ 1.5% max (with ultra-low chloride specialty grades guaranteed ≤ 0.5% max). Granular SOP is precision-screened to 2.0–4.0 mm (≥ 90%) with a Size Guide Number (SGN) of 200–300, crushing strength of ≥ 3.0 kgf, and anti-caking conditioning to prevent breakdown during bulk blending with granular urea, DAP, and MAP. Water-soluble SOP (fertigation grade) is a crystalline white salt with 100% aqueous solubility (110–120 g/L at 20 °C) and insolubles strictly ≤ 0.1%, ensuring zero blockage of micro-emitters in drip systems. Agronomically, SOP is critical for chloride-sensitive crops (tobacco, potatoes, citrus, berries, table grapes, avocados, greenhouse vegetables, and tea), where chloride induces leaf burn, lowers tuber dry-matter/starch, impairs combustibility, and reduces fruit shelf life. SOP is also essential in arid, saline, or poorly drained soils where continuous chloride application leads to phytotoxic soil salinity.
