We supply a comprehensive range including NPK compound fertilizers (15-15-15, 20-10-10, 10-10-20), water-soluble fertilizers for fertigation, bio-enhanced products (humic acid, seaweed extract, amino acids), crop-specific blends, and industrial chemicals (urea 46%, ammonium sulphate, DAP, MAP).

NPK stands for Nitrogen (N), Phosphorus (P₂O₅), and Potassium (K₂O) — the three primary macronutrients plants need. The numbers represent the percentage of each nutrient by weight. For example, NPK 15-15-15 contains 15% nitrogen, 15% phosphorus pentoxide, and 15% potassium oxide.

Humic acid is a large molecule that primarily improves soil structure, increases cation exchange capacity, and stimulates microbial activity — best applied as a soil amendment. Fulvic acid is a smaller molecule that can penetrate plant cell membranes, making it ideal for foliar sprays. It enhances nutrient absorption and provides rapid results. Both work synergistically when used together.

Our bio-enhanced product line — including seaweed extract, humic acid, and amino acid chelates — is suitable for use in organic and integrated production systems. Our microbial biofertilizer range includes products compatible with organic certification standards. NPK compound and industrial fertilizers are conventional chemical products. Contact us for specific certification details.

Most of our granular and compound fertilizers have a shelf life of 24-36 months when stored properly in dry, well-ventilated conditions. Water-soluble fertilizers should be used within 24 months. Liquid products (humic acid, seaweed extract) have a 12-24 month shelf life. Always store fertilizers away from direct sunlight and moisture.

Yes, we supply both DAP (diammonium phosphate, 18-46-0) and MAP (monoammonium phosphate, 11-52-0) in agricultural and technical grades. Both are available in 50 kg bags and bulk packaging with worldwide shipping.

Urea 46% (46-0-0) is the world’s most concentrated solid nitrogen fertilizer. It is used for top-dressing cereals, side-dressing corn, and providing nitrogen to a wide range of crops. It’s also used industrially for AdBlue/DEF production, adhesives, and animal feed supplements.

Our minimum order quantity varies by product. For containerized shipments, the MOQ is typically 20 MT (one 20-foot container). For water-soluble and specialty products, smaller trial orders starting from 1 MT may be available. Contact our sales team for specific product MOQs.

We ship worldwide from our base in Wrocław, Poland. Our key markets include West Africa (Nigeria, Ghana, Senegal, Côte d’Ivoire), East Africa (Kenya, Ethiopia, Tanzania), Southeast Asia (Vietnam, Thailand, Indonesia), South America (Brazil, Argentina, Colombia), and throughout Europe. We offer both FOB and CIF pricing.

We accept various payment methods including bank transfer (T/T), letter of credit (L/C), and for established customers, open account terms. Standard terms are 30% advance payment with 70% against shipping documents. Specific terms can be negotiated based on order volume and relationship.

Shipping times depend on the destination: Europe (3-7 days by truck), West Africa (12-18 days by sea), East Africa (18-25 days), Southeast Asia (25-35 days), South America (20-28 days). These are approximate transit times after vessel departure. Total lead time including production and loading is typically 2-4 weeks.

We offer flexible packaging: 10 kg bags (water-soluble products), 25 kg bags, 50 kg bags, 1 MT jumbo bags (big bags), and bulk loading. Custom labeling and private label services are available for orders above 100 MT. All packaging meets international shipping standards.

Yes, every shipment comes with a Certificate of Analysis (CoA) from an independent laboratory, plus Material Safety Data Sheet (MSDS), packing list, commercial invoice, and all required export documentation. Additional certificates (phytosanitary, origin, etc.) are provided as required by the destination country.

Yes, we offer custom NPK blending services for orders above 100 MT. You specify the nutrient ratios and we manufacture to your exact specifications. Custom blends typically require 4-6 weeks lead time. Contact our technical team to discuss your requirements.

Application rates depend on the crop, soil conditions, and target yield. General guidelines: cereals (wheat, corn) need 300-500 kg NPK/ha, vegetables need 400-800 kg/ha, fruit trees need 200-500 g/tree. Always base application rates on soil test results and crop nutrient removal data. Our technical team can provide specific recommendations for your operation.

Optimal timing varies by crop and nutrient: apply phosphorus and potassium at planting or before sowing, apply nitrogen in 2-3 split applications during active growth. Avoid fertilizing during heavy rain (causes leaching), extreme heat (causes volatilization), or when soil is frozen. Early morning or late afternoon is best for foliar applications.

Some fertilizers can be mixed, but others are incompatible. Safe to mix: NPK granulars with urea, MAP with potassium chloride. Avoid mixing: calcium-containing fertilizers with phosphorus or sulfate fertilizers (causes precipitation), urea with ammonium nitrate (hygroscopic). For water-soluble fertilizers, always check compatibility before tank mixing.

Dissolve the fertilizer in clean water at the recommended concentration (typically 0.5-2 kg per 1,000 L). Inject into the irrigation system using a venturi injector or dosing pump. Monitor EC (electrical conductivity) to avoid salt damage. Start and end each fertigation cycle with clean water to prevent clogging. Target pH 5.5-6.5 in the solution.

Granular fertilizers are solid particles applied to soil — they’re easy to store, have long shelf life, and release nutrients over weeks. Liquid fertilizers are dissolved solutions applied through irrigation or foliar spray — they provide immediate nutrient availability and precise dosing. Granular is better for base application; liquid is better for in-season correction.

Seaweed extract contains natural plant hormones (cytokinins, auxins), alginates, amino acids, and micronutrients that stimulate root growth, improve stress tolerance, enhance nutrient uptake, and boost yields by 10-25%. Apply as foliar spray (0.2-0.5% solution) every 2-3 weeks or through drip irrigation at 2-5 L/ha.

Multiply the amount of fertilizer by its nitrogen percentage. For example: 200 kg of urea 46% = 200 × 0.46 = 92 kg N/ha. For NPK 20-10-10 at 300 kg/ha: 300 × 0.20 = 60 kg N/ha. Always calculate total N from all sources to avoid exceeding crop requirements or regulatory limits.

Fertilizer burn occurs when salt concentration around roots is too high, drawing water out of plant cells. Common causes: applying too much fertilizer at once, placing fertilizer too close to seeds or stems, fertilizing during drought without irrigation, and using high-salt fertilizers on sensitive crops. Prevention: follow recommended rates, incorporate into soil, and irrigate after application.

Band application (placing fertilizer in a concentrated band near roots) is 2-3x more efficient than broadcasting for phosphorus and potassium because it reduces soil fixation. Broadcasting is acceptable for nitrogen (mobile in soil) and for established pastures. For row crops, band application at planting is the most cost-effective method.
