What Is YaraMila Complex (12-5-15)?
YaraMila Complex (12-5-15) is a high-quality, granulated fertiliser containing a balanced ratio of Nitrogen (N), Phosphorus (P), and Potassium (K)—the three most critical nutrients for plant growth. The numbers 12-5-15 represent the percentage of each nutrient in the blend:
- 12% Nitrogen (N) – Promotes leafy green growth and overall plant vigour.
- 5% Phosphorus (P) – Supports strong root development and flowering.
- 15% Potassium (K) – Enhances fruit quality, disease resistance, and drought tolerance.
This fertiliser also includes secondary nutrients (Calcium, Magnesium, Sulfur) and micronutrients (Zinc, Boron, Iron), ensuring a well-rounded nutrient supply for optimal plant health.

Why Choose a Balanced NPK Fertiliser?
Many fertilisers focus heavily on one nutrient (like nitrogen for leafy growth), but an imbalanced approach can lead to poor fruiting, weak roots, or nutrient deficiencies. YaraMila’s 12-5-15 ratio is ideal for crops that need:
- Strong vegetative growth (thanks to nitrogen)
- Healthy root systems (from phosphorus)
- High-quality fruits or flowers (due to potassium)
This makes it perfect for vegetables, fruit trees, turf, and broadacre crops—especially in Australia’s diverse soil conditions.

Benefits of Using YaraMila Complex (12-5-15)
1. Improved Crop Yield & Quality
A well-balanced fertiliser ensures that plants get the right nutrients at every growth stage. Farmers using YaraMila report:
- Higher yields due to better nutrient uptake
- More uniform crop maturity
- Improved taste and shelf life of fruits and vegetables
2. Stronger Root Systems
Phosphorus is essential for root development, making plants more resilient to drought and soil stress.
3. Enhanced Disease & Stress Resistance
Potassium helps plants withstand heat, cold, pests, and diseases, reducing the need for excessive pesticides.
4. Efficient Nutrient Uptake
YaraMila’s granules dissolve gradually, providing a steady nutrient release and minimising leaching (wastage).
5. Suitable for a Wide Range of Crops
From tomatoes and corn to citrus trees and lawns, this fertiliser supports healthy growth across many plant types.

How to Apply YaraMila Complex (12-5-15) for Best Results
1. Soil Preparation & Testing
Before applying any fertiliser, it’s best to test your soil’s pH and nutrient levels. This helps avoid over- or under-fertilising.
2. Application Methods
- Broadcasting: Spreading granules evenly over the soil (ideal for large fields).
- Banding: Placing fertiliser in rows near seeds (great for row crops like corn).
- Top-Dressing: Applying around established plants (used for fruit trees and turf).
3. Recommended Dosage
Crop Type | Application Rate |
---|---|
Vegetables | 30–50 kg per 100 sqm |
Fruit Trees | 100–200 g per tree |
Turf & Lawns | 20–30 kg per 1000 sqm |
Broadacre Crops | 200–400 kg per hectare |
Always follow label instructions and adjust based on soil tests.
4. Timing Matters
- Pre-planting: Apply before sowing to boost early growth.
- During Growth: Side-dress when plants are actively growing.
- Post-Harvest: Replenish soil nutrients after harvest.

Common Fertiliser Mistakes to Avoid
1. Over-Fertilising
Too much fertiliser can burn roots, stunt growth, and harm soil microbes. Stick to recommended rates.
2. Ignoring Soil pH
If soil is too acidic or alkaline, plants can’t absorb nutrients properly. Lime or sulfur may be needed to balance pH.
3. Applying at the Wrong Time
Fertilising during extreme heat or before heavy rain can lead to nutrient loss.
4. Not Using Protective Gear
Always wear gloves and a mask when handling fertiliser to avoid skin and respiratory irritation.

Why Sustainable Fertiliser Use Matters
Modern farming isn’t just about high yields—it’s about long-term soil health. YaraMila’s balanced formula helps:
- Reduce nutrient runoff (protecting waterways)
- Maintain soil fertility for future crops
- Lower the need for synthetic pesticides
By choosing the right fertiliser, you’re investing in both productivity and environmental care.
Final Thoughts
YaraMila Complex (12-5-15) is a game-changer for anyone serious about crop health and yield. By understanding how to use it effectively, you can boost productivity, improve plant resilience, and grow healthier, more abundant crops.
