Full product details

Product overview

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 is classified as an oxidiser (UN 1474) and requires dedicated storage away from combustibles. Crystalline grade moves in moisture-proof packaging to prevent caking during transit through humid ports.

FOB loading at Black Sea chemical terminals and MENA nitrate complexes. Parcel sizes from 1,000 MT (coaster or containerised big-bag lots) to 3,000 MT on multipurpose or container vessels for bagged cargo.

CFR/CIF deliveries to South Asia (Nhava Sheva, Karachi), East Africa (Mombasa), the Gulf (Jebel Ali, Dammam) and Mediterranean horticulture hubs. Bagged shipments in 25 kg PP woven bags with PE liner or 1,000 kg FIBC suit ports without bulk nitrate handling licences.

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

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

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.
