Product overview — Magnesium Nitrate 11-15
Magnesium nitrate delivers nitrate nitrogen and soluble magnesium in a single highly water-soluble crystalline salt. The 11-15 analysis (11% N, 15% MgO) is the standard corrective for magnesium deficiency in recirculating hydroponics, greenhouse drip systems and foliar programmes on fruiting vegetables. Magnesium sits at the centre of the chlorophyll molecule — deficiency shows as interveinal yellowing on older leaves and directly limits photosynthetic output.
Low water-insoluble content (0.1% max) keeps fertigation injectors and precision dosing systems clean. Unlike magnesium sulphate, magnesium nitrate adds no sulphur — choose it when tissue analysis shows both Mg and nitrate-N deficits without a sulphur requirement. Crystalline product dissolves rapidly at 20 °C and pairs naturally with calcium nitrate in twin-tank A/B fertigation setups, where both cations are supplied in the B-concentrate.
Supply origins include nitrate complexes in Europe, the Middle East and Central Asia. Export buyers include greenhouse operators in the Gulf and Levant, soluble-fertilizer blenders in South Asia, and distributor networks serving Mediterranean berry and vegetable production.

Loading ports & logistics — Magnesium Nitrate 11-15
Magnesium nitrate (UN 1474 oxidiser) requires licensed oxidiser storage away from combustibles. Contract MOQ 1,000 MT ships in 25 kg PP bags or 1,000 kg FIBC assembled into container or coaster parcels for greenhouse hydroponics hubs; multipurpose vessel lots from 3,000 MT suit importers with oxidiser-handling berths at Nhava Sheva, Karachi, Jebel Ali and Dammam.
FOB loading at Black Sea chemical terminals and MENA nitrate complexes. Crystalline flakes and prills move in moisture-proof packaging to prevent caking during transit through humid ports.
CFR/CIF deliveries to South Asia, East Africa, the Gulf and Mediterranean horticulture hubs. Typical lead time 14–30 days from contract to loading window, subject to ADR/IMDG documentation and berth scheduling for oxidiser-class cargo.
Packaging & documentation — Magnesium Nitrate 11-15
25 kg PP woven bags with inner PE liner, palletised and stretch-wrapped; 1,000 kg FIBC big-bags for greenhouse complexes with bulk dissolution tanks; or vessel-hold lots in moisture-barrier packaging. Store sealed in dry conditions below 25 °C to prevent caking. Each consignment ships with a mill certificate of analysis (COA), commercial invoice, packing list, bill of lading and certificate of origin. SDS per GHS and transport declarations for oxidiser-class cargo are included. SGS or Bureau Veritas inspection at loading available for LC-backed or first-time contracts.
FAQ — Magnesium Nitrate 11-15
When should growers choose magnesium nitrate over magnesium sulphate?
Use magnesium nitrate when both magnesium and nitrate nitrogen are needed — typical in recirculating hydroponics and intensive greenhouse fertigation. Magnesium sulphate (Epsom salt) suits programmes that require sulphur alongside Mg but no additional nitrogen. Match the source to leaf-tissue and nutrient-solution analysis.
What concentration is safe for foliar magnesium nitrate sprays?
Apply a 1–2% solution (10–20 g/L) on fruiting crops during early fruit set or when interveinal chlorosis appears on older leaves. Spray during cool morning hours below 30 °C ambient temperature to limit leaf scorch from rapid surface drying.
What packaging and MOQ apply to bulk magnesium nitrate export?
Minimum order is 1,000 MT. Crystalline grade ships in 25 kg bags, 1,000 kg FIBC big-bags or vessel lots from Black Sea and MENA load ports. Each consignment includes a mill COA; SGS or Bureau Veritas inspection at loading is available on request.
