Potassium chloride (MOP)

Also known as: KCl, muriate of potash

Full explanation

In Ukraine KCl is fully imported — the country has no potash salt deposits. Pre-2022 suppliers: Belaruskali, Uralkali (both now under sanctions); post-2022 main sources: Canada (Nutrien, Mosaic, Canpotex), Israel (ICL), Jordan (APC), Germany (K+S). Application rates: cereals 60–120 kg K₂O/ha (100–200 kg/ha physical weight), sugar beet 180–240 kg K₂O/ha, sunflower 90–120 kg K₂O/ha. April 2026 price: UAH 19 000–23 000/t [VERIFY]. Applied in autumn with primary tillage — potassium doesn't leach from chernozems and binds well to the soil complex. Trade-off: MOP is cheap, but chlorine-sensitive crops require potassium sulfate (SOP, K₂SO₄, 50% K₂O) — 1.5–2× more expensive. K deficiency on chernozems is rare, so blanket 'balancing' applications often don't pay — targeted variable-rate application based on soil maps is recommended.
