Reliable Global Supply of Calcium Magnesium

We supply calcium magnesium fertilizers to importers, distributors, specialty fertilizer companies, and crop production operations requiring targeted secondary macronutrient programs. Products include calcium magnesium nitrate, dolomitic granules, magnesium sulphate (kieserite and Epsom salt), and calcium-magnesium liquid concentrates. Supply is subject to grade availability and buyer requirements.

Wholesale supply only

We supply business buyers only — no retail sales. Orders ship as LCL or FCL.

Read the full Calcium Magnesium product overview

Calcium and magnesium are essential secondary macronutrients that are frequently overlooked in fertilizer programs focused on N, P, and K. Calcium is critical for cell wall integrity, root development, and reduction of physiological disorders such as blossom-end rot (BER) in tomato and pepper, bitter pit in apple, and tip-burn in lettuce and cabbage. Magnesium is the central atom of the chlorophyll molecule and is essential for photosynthesis, enzyme activation, and phosphorus transport within the plant.

Key products in our calcium magnesium range include: Calcium Magnesium Nitrate (CMN) — a fully water-soluble grade providing approximately 10–11% N, 19% CaO, and 3–4% MgO for fertigation use; Dolomite and dolomitic limestone — agricultural-grade Ca + Mg carbonate for pH correction and basal Ca + Mg supply; Kieserite (MgSO₄·H₂O) — granular magnesium sulphate with approximately 27% MgO and 22% S, widely used in plantation and oilseed programs; Magnesium sulphate heptahydrate (Epsom salt, MgSO₄·7H₂O) — fully soluble grade for foliar and fertigation programs. Liquid calcium and liquid magnesium concentrates are also available for tank-mix and fertigation use.

We source these products from approved producers in Europe, China, Turkey, Israel, and other verified origins. Each product comes with a COA, safety data sheet where applicable, and full export documentation.

Frequently Asked Questions

What calcium magnesium fertilizer grades do you supply?

Our range includes Calcium Magnesium Nitrate (for fertigation), Kieserite (granular MgSO₄), Epsom salt (soluble MgSO₄·7H₂O), dolomitic limestone (Ca + Mg carbonate), and liquid calcium and magnesium concentrates. Please specify the form, target nutrient content, and application method when enquiring so we can confirm the most suitable grade.

What is the MOQ for calcium magnesium fertilizers?

MOQ varies by grade and origin. Granular grades can ship LCL (part-container load) or as full 20ft containers (FCL) of roughly 20–25 MT. Liquid grades in IBC totes start from 5–10 MT. Soluble grades (Epsom salt, CMN) can sometimes be ordered in smaller quantities. We will confirm origin-specific minimums with each quotation.

What origins do you source calcium magnesium fertilizers from?

We source from producers in Europe (including Turkey and Norway for CMN), China (kieserite, Epsom salt), and Israel (specialty grades), among other approved origins. Origin selection depends on the specific product, price, lead time, and destination market compliance.

Is independent inspection available?

Yes. SGS or Intertek inspection at load port can be arranged for granular and soluble grades. Inspection covers quantity survey, sampling, and COA verification. For liquid grades, volume measurement and density check are included. Inspection costs are agreed as part of the contract.

What documentation is provided with calcium magnesium fertilizer shipments?

Standard documents include Commercial Invoice, Packing List, Certificate of Origin, Certificate of Analysis, and Bill of Lading. MSDS/SDS, inspection certificates, and phytosanitary or import documents required by the destination authority are arranged on request.

What Incoterms do you offer?

FOB, CFR, and CIF terms are available. EXW may be available from European origins. Please specify your destination port and preferred Incoterms when requesting a quote so we can confirm logistics feasibility.

Product availability, pricing, origin, documentation, and shipment terms are subject to supplier confirmation, destination regulations, sanctions screening, and contract agreement.
