Potassium Nitrate & Calcium Nitrate

NOP 13-0-46 and calcium nitrate 15.5% N for fertigation

Potassium nitrate and calcium nitrate are the two nitrate salts at the core of fertigation. NOP 13-0-46 supplies potassium and nitrate nitrogen with no chloride, fully water-soluble in its greenhouse grade and prilled or granular for field use; calcium nitrate at 15.5% total nitrogen (about 14.4% nitrate and 1.1% ammoniacal) with about 26.5% CaO is the soluble calcium source that prevents blossom-end rot, bitter pit and tipburn in tomatoes, peppers, apples and leafy crops. The two cannot share a stock tank with sulphates and phosphates because calcium precipitates, so growers run them in an A tank alongside micronutrient chelates. Fertigation grades are contracted on nutrient content, water-insolubles, pH, sodium and chloride, and on free-flowing crystals or prills; field grades on nutrients, moisture and size.

The 2024 trade data put reported potassium nitrate exports (HS 2834.21) at about USD 0.79 billion, led by Chile (42.6%), Jordan (14.3%), the Netherlands (12.5%) and China (12.4%), with Spain and Denmark behind; calcium nitrate (HS 3102.60) at about USD 0.36 billion, led by China (36.9%), South Africa (17.0%), Czechia (8.7%), Slovakia (8.1%) and Egypt (7.5%). Both salts are reportable explosives precursors under EU Regulation 2019/1148, and many importing countries require an import permit for nitrates, so every order is placed against a named receiver, stated agricultural end use and the destination's licence. Egypt applies a 10% export duty on nitrogen fertilizers under Decree No. 258 of 2026. CBIL brokers both against an SGS, Intertek or Bureau Veritas certificate of analysis and a certificate of origin, in 25 kg lined bags, 50 kg bags and jumbo bags. Prices are negotiated per MT on grade, with published specialty fertilizer assessments as reference points.
