Our Fertilizer Material Categories
Four product families covering everything from straight nutrients to ready-formulated water-soluble blends.
Macronutrients
Urea, phosphate, and potassium sources — the core nitrogen, phosphorus, and potassium inputs for fertilizer blending.
Secondary & Micronutrients
Magnesium, manganese, copper, iron, and zinc sulphates, oxides, and chlorides for trace nutrient correction.
Water-Soluble NPK Blends
Ready-formulated NPK Plus blends for fertigation and water-soluble application, in granular or powder form.
Nitrogen & Soil Amendments
Ammonium Chloride and nitrification inhibitors for nitrogen management and soil conditioning.

Understanding Our Fertilizer Raw Material Categories
What each product is used for, and how to choose between them.
Macronutrients
Urea (46-0-0) is the most concentrated solid nitrogen fertilizer available and a standard input for blenders worldwide, alongside Ammonium Sulfate and Sodium Nitrate as alternative nitrogen sources with different secondary nutrient profiles. Monoammonium Phosphate (MAP), Diammonium Phosphate (DAP), and Monopotassium Phosphate (MKP) supply phosphorus alongside nitrogen or potassium respectively, with MKP being fully water-soluble and popular in fertigation programs; Phosphoric Acid serves as the base phosphate input for blenders manufacturing their own phosphate fertilizers. Urea Phosphate combines nitrogen and phosphorus in a single water-soluble compound. Potassium Chloride (MOP) is the most widely used and cost-effective potassium source, while Potassium Sulphate (SOP) is preferred for chloride-sensitive crops, and Potassium Nitrate supplies both potassium and nitrate-form nitrogen for premium and fertigation applications.
Secondary & Micronutrients
Magnesium Oxide, Magnesium Sulphate, and Magnesium Chloride all correct magnesium deficiency, with Magnesium Oxide offering a higher concentration for granular blends and the sulphate and chloride forms offering faster solubility for liquid or water-soluble applications. Manganese Sulphate, Copper Sulphate, Copper Sulfate Monohydrate, Copper Chloride Hydroxide, Iron Sulphate, and Zinc Sulphate round out the core micronutrient package most blended fertilizer programs need to correct trace element deficiencies in crops. Potassium Bicarbonate offers a foliar-applicable potassium source, Calcium Carbonate serves as an agricultural liming material for soil pH correction, and Phosphorus Acid functions as both a phosphonate fertilizer input and a fungicidal aid.
Water-Soluble NPK Blends
Our 13-40-13 PLUS, 15-5-30 PLUS, 19-6-20 PLUS, 20-20-20 PLUS, and 7-12-40 PLUS blends are ready-formulated NPK products for water-soluble and fertigation use, each ratio suited to different crop stages — high-phosphorus blends like 13-40-13 for root development and flowering, balanced 20-20-20 for general feeding, and high-potassium blends like 7-12-40 for fruit fill and quality. All are available in granular or powder form depending on the blend and application method.
Nitrogen & Soil Amendments
Ammonium Chloride provides a straightforward nitrogen source used in some regional blending programs where chloride sensitivity isn’t a concern. Dicyandiamide is a nitrification inhibitor, applied alongside nitrogen fertilizers to slow the conversion of ammonium to nitrate, reducing nitrogen losses through leaching and improving overall nitrogen use efficiency.
Which NPK Plus Blend Fits Your Crop Stage?
| Blend | Profile | Best suited for |
|---|---|---|
| 13-40-13 PLUS | High phosphorus | Root development, flowering, and transplant establishment |
| 15-5-30 PLUS | High potassium | Fruit development and general fertigation programs |
| 19-6-20 PLUS | Balanced N-K | Vegetative growth through to early fruiting |
| 20-20-20 PLUS | Balanced all-purpose | General feeding across most growth stages |
| 7-12-40 PLUS | Very high potassium | Fruit fill, quality, and ripening stages |
Straight Nutrients or Ready-Made NPK Blends?
The right choice depends on whether you’re formulating your own blend or need a ready-to-apply product. Fertilizer blenders and co-ops typically buy straight nutrients, Urea, MAP, MOP, SOP, and the individual micronutrient sulphates, so they can control the exact NPK ratio and micronutrient package for their specific market or crop. This is generally the more cost-effective route for anyone blending at scale as a fertilizer raw materials supplier’s core customer base.
Growers, distributors, and smaller operations without blending equipment, on the other hand, are usually better served by our ready-formulated water-soluble NPK Plus blends, which arrive at a fixed, tested ratio suited to a specific growth stage, high-phosphorus 13-40-13 for establishment, balanced 20-20-20 for general feeding, high-potassium 7-12-40 for fruit fill. If you’re unsure which route fits your operation, tell us your crop, growth stage, and whether you have blending capability, and we can recommend straight nutrients or a Plus blend accordingly.
Frequently Asked Questions
What does a fertilizer raw materials supplier provide?
A fertilizer raw materials supplier provides the macronutrient, secondary nutrient, and micronutrient inputs used by fertilizer blenders and formulators to produce their own blended products, as well as ready-made water-soluble NPK blends for direct application.
Do you supply fertilizer raw materials internationally?
Yes — Terracore Chemicals exports fertilizer raw materials from South Africa to customers across Africa and internationally, with bulk shipping options.
Are the NPK Plus blends available in both granular and powder form?
Yes, depending on the specific blend — confirm the form you need when requesting a quote.
Can I get technical documentation with my order?
Yes, Certificates of Analysis and spec sheets are available on request for every product in this range.
Do you supply smaller trial quantities as well as bulk orders?
In most cases, yes — get in touch with your required volume and we’ll confirm options.
Should I buy straight nutrients or a ready-made NPK blend?
It depends on whether you blend your own product. Blenders and co-ops typically buy straight nutrients like Urea, MAP, and MOP to control their own formulation, while growers and distributors without blending capability are usually better served by our ready-formulated water-soluble NPK Plus blends.
