Product Description

The Complete Balanced Fertilizer – 45% Total Nutrients

NPK 15‑15‑15 Compound Fertilizer is a ternary compound fertilizer, meaning it contains all three primary macronutrients: nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O), each at a concentration of 15% , resulting in a total nutrient content of 45% . The three numbers in the label represent the percentage by weight of each nutrient, making this a perfectly balanced formula. This universal, all‑purpose fertilizer is used widely in agriculture to supply the basic nutritional needs of various crops at different growth stages .

Core Nutrient Functions

🔬 Key Technical Specifications

All specifications are typical for high‑quality agricultural grade compound NPK 15‑15‑15. Values are based on the dry, anhydrous product.

Nitrogen Source Breakdown
The nitrogen component in NPK 15‑15‑15 is typically a blend: approx. 6% nitrate‑N (for immediate availability) and 9% ammonium‑N (for steady release) . This dual‑action approach ensures both a rapid greening response and sustained nutrition.

✨ Key Features & Benefits for Crop Yield

• Perfectly Balanced 15‑15‑15 Ratio: Delivers equal amounts of the three essential primary nutrients for uniform crop development and simplified fertiliser management.

• High Nutrient Density (45%): Reduces handling, storage, and transport costs per kilogram of delivered nutrients, improving operational efficiency.

• Granular Formulation (2‑5 mm): Easy to spread evenly with standard broadcast equipment, ensuring uniform plant nutrition.

• Quick Release: Nutrients become available to plants rapidly after application, providing an immediate boost to growth.

• Versatile Application Methods: Can be broadcast, incorporated into the soil, banded, top‑dressed, or (if water‑soluble grade) applied through fertigation.

• Time‑Efficient: Using NPK 15‑15‑15 reduces the frequency of application needed compared to using singular nutrient fertilizers, saving time and labour costs .

• Consistent Results: Provides reliable outcomes irrespective of soil or crop characteristics, with a proven track record for enhancing crop growth and yield.

🌱 Agronomic Benefits & Crop Applications

NPK 15‑15‑15 is suitable for a wide range of agricultural systems, including field crops, vegetables, fruit trees, and horticultural plants. It is listed as suitable for a variety of vegetables, fruit trees, flowers, and field crops .

🌿 With or Without Trace Elements (TE) / Secondary Nutrients

NPK 15‑15‑15 is also available with added secondary nutrients (such as Sulphur – S) and Trace Elements (TE). The sulphur content ensures a high intake of nitrogen and phosphorus by plants, and potassium facilitates faster transport of synthesis products (carbohydrates) to root vegetables and seeds . A variant like NPK 15:15:15 + 11% S (SOP – Sulphate of Potash) is particularly suitable for chloride‑sensitive crops.

🧪 Quality Control & Manufacturing Excellence

Our NPK 15‑15‑15 compound fertilizer is manufactured using high‑tower technology and is tested according to international standards, including GB/T 15063‑2020 for high‑concentration compound fertilizers . Each batch is guaranteed to meet the high concentration standard for compound fertilizers.

• Production Process: High‑tower granulation → drying → cooling → screening → coating.

• Quality Tests: Nitrogen content, phosphorus content, potassium content, particle size distribution, moisture control, biuret levels.

• Facility Certifications: ISO 9001, SGS.

🧪 Recommended Application Rates

General application rates vary depending on soil condition, structure, humus content, pH level, and the presence of useful elements. Before fertilising, soil testing is strongly recommended.

For best results, have your soil tested annually by a qualified laboratory. All rates are general guidelines; a professional agronomist should confirm the exact rate based on your specific soil analysis, target crop, and yield goal.

Application Methods:

• Broadcast / Top‑dressing: Spread evenly over the soil surface, preferably before rain or irrigation.

• Incorporation: Mix into the top 5‑10 cm of soil for best efficiency and to minimise ammonia volatilisation.

• Band / Side‑dressing: Place in bands 5‑8 cm to the side of the seed row to avoid seed burn.

• Fertigation (where water‑soluble grade is specified): Dissolve and inject into irrigation water.

⚠️ Important Application Precautions:

• Incorporation is recommended after application, especially in warm conditions (>15°C), to minimise ammonia volatilisation (nitrogen loss to the air).

• Avoid direct contact of concentrated fertilizer with seeds or young roots, as this may cause germination damage or root burn.

• For best results, use in conjunction with a proven nutrient management plan and follow the advice of a qualified agronomist.

🧴 Storage & Shelf Life

🚜 Best Management Practices for NPK Fertilizer Storage

• Location: Store in a cool, dry, clean, well‑ventilated, roofed area with a moisture‑proof foundation . Keep away from clothing, chemicals and combustible materials .

• Prevent Moisture: Keep bags sealed and off the floor. Urea and NPK blends are hygroscopic and will cake if exposed to high humidity.

• Avoid Contamination: Store separately and keep away from poisonous substances and sources of ignition .

• Security: Keep out of reach of children (P102) . Ensure correct signage and restrict access.

• Temperature: Keep away from sources of heat, open flame, and direct sunlight. It is recommended to store the product at temperatures below 30 °C.

❓ Frequently Asked Questions (FAQs)

Q: What does NPK 15‑15‑15 mean?
A: The numbers represent the percentage by weight of nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O) in the fertilizer. NPK 15‑15‑15 contains 15% of each primary nutrient, resulting in a total nutrient content of 45% .

Q: Is NPK 15‑15‑15 a complete fertilizer?
A: Yes. NPK 15‑15‑15 is considered a general‑purpose, complete fertilizer because it provides all three primary macronutrients (N, P, K) in equal proportions . It supplies the basic nutritional needs of various crops at different growth stages .

Q: What are the advantages of using a balanced 15‑15‑15 fertilizer?
A: It provides uniform crop nutrition, simplifies fertiliser management, reduces the number of applications needed compared to single‑nutrient fertilizers (saving time and labour) , and lowers handling, storage, and transport costs per kilogram of delivered nutrient.

Q: Is this fertilizer water‑soluble for use in fertigation systems?
A: Standard NPK 15‑15‑15 granular fertilizer is water‑soluble to a certain degree but is primarily designed for soil application (broadcast, top‑dressing, side‑dressing). A fully water‑soluble grade is available and is suitable for fertigation and foliar spraying. Please specify your requirement at the time of ordering.

Q: What is the difference between granular and powdered NPK 15‑15‑15?
A: Granular NPK (2‑5 mm) is free‑flowing, easier to spread evenly with broadcast equipment, and has a lower dust content. Powdered NPK is cheaper, dissolves faster, and is more suitable for liquid mixing but can be dusty and more difficult to spread evenly. Our standard product is granular.

Q: Is NPK 15‑15‑15 suitable for organic farming?
A: Synthetic NPK fertilizers are not permitted for use in certified organic farming systems. This product is intended for conventional agriculture. Please check with your certification body for approved N, P, and K sources.

Q: How should NPK 15‑15‑15 be stored to prevent caking?
A: Store in a cool, dry, well‑ventilated area, away from direct sunlight. Keep bags tightly sealed and off concrete floors to prevent moisture absorption. The shelf life is typically 3 years when stored correctly .

Q: What is the difference between NPK 15‑15‑15 and NPK 15‑15‑15+TE?
A: The standard NPK 15‑15‑15 contains only the three primary nutrients (N, P, K). The +TE version is enriched with Trace Elements (such as zinc, boron, iron, manganese, copper, molybdenum) and sometimes secondary nutrients (like sulphur), which can be beneficial for specific crops or soils with known micronutrient deficiencies.

Q: Is NPK 15‑15‑15 compatible with other fertilizers for bulk blending?
A: NPK 15‑15‑15 is compatible with many other dry fertilizers (such as urea, DAP, MAP, potash). However, it has limited compatibility with certain products. Confirm compatibility with your agronomist or refer to the product’s technical data sheet before blending large volumes.

Q: How can I calculate the amount of NPK 15‑15‑15 I need per hectare?
A: For a balanced application, decide on your desired N rate. To apply 100 kg of N per hectareusing NPK 15‑15‑15, you need approximately 667 kg of product per hectare (because 100 ÷ 0.15 = 666.7). This will also supply 100 kg of P₂O₅ and 100 kg of K₂O per hectare.
