BB Fertilizer, also known as Bulk Blended NPK Fertilizer, is a scientifically blended product made by physically mixing single or compound fertilizers. Its main components—Nitrogen (N), Phosphorus (P₂O₅), and Potassium (K₂O)—are tailored into specific ratios based on soil fertility, crop type, and climatic conditions. Additional macro- and micronutrients such as Ca, Mg, S, Fe, Zn, Cu, Mn, B, Mo can be incorporated as needed.
This type of fertilizer ensures cost-effective, targeted nutrition with high purity and flexible formulations for modern farming needs.
Customizable NPK Formulations: Available in diverse ratios such as 10-10-20, 12-24-12, 20-10-10, 13-13-21, etc.
Quick Nutrient Release: Promotes rapid nutrient uptake by crops.
Uniform Granule Size: 2–5mm for even application and absorption.
Low Moisture Content: ≤ 2%, ensuring long shelf life and resistance to caking.
High Compatibility: Can include EDTA-chelated micronutrients for improved bioavailability.
Eco-Friendly: Supports reduced application frequency and nutrient loss.
Field Crops: Corn, wheat, rice, soybeans
Vegetables: Tomatoes, peppers, cucumbers, carrots, leafy greens
Fruits: Citrus, apples, grapes, berries
Flowers & Ornamentals: Roses, petunias, marigolds, turfgrass
Lawns & Public Greens: Residential, golf courses, parks

1. Base Dressing:
Incorporate into the soil before sowing or transplanting to provide long-term nutrition and improve root establishment.
2. Top Dressing:
Apply during crop growth to meet stage-specific nutrient demands. Common techniques include:
Spreading (broadcasting)
Banding or dibbling near root zones
Nesting or radial applications for fruit trees
3. Seed Fertilization:
Can be applied with or near seeds during planting. Careful dosage is needed to avoid seed damage.
