short description:

Polymer Coated NPK 12-12-17 + Additives – Balanced Horticulture Fertilizer

Polymer Coated NPK 12-12-17 with 2 percent MgO, Fulvic Acid, Amino Acid, Humic Acid, 8 percent Organic Matter (OM), and Trace Elements (TE) provides comprehensive nutrition for horticulture, flowers, nursery plants, and fruit trees. Engineered for 180-360 day controlled release, its polymer coating ensures gradual nutrient delivery synchronized with long-growth cycles. The balanced 12-12-17 NPK ratio supports vigorous growth, flowering, and fruiting, while 2 percent magnesium oxide enhances photosynthesis efficiency. Organic additives (2 percent fulvic acid, 3 percent humic acid, 1.5 percent amino acids) improve soil structure, nutrient uptake, and stress tolerance. TE prevents micronutrient deficiencies in intensive production. Ideal for container nurseries and orchard establishment, this blend reduces leaching by 60 percent and salt index by 35 percent versus conventional fertilizers. Uniform 3.0-4.5 mm granules ensure even distribution in potting media and field soils. Customize release duration (180/240/300/360 days) for crop-specific programs. Optimize plant health and productivity with reduced application frequency.

KEY BENEFITS
1. Balanced Growth Support
12-12-17 NPK promotes root development, flowering, and fruit maturation simultaneously.

2. Stress Mitigation
Amino acids reduce abiotic stress; humic acids improve drought resistance.

3. Soil Enhancement
8 percent OM increases cation exchange capacity in degraded soils.

4. Nutrient Efficiency
Polymer coating reduces leaching losses by 60 percent in high-rainfall regions.

5. Micronutrient Security
TE package prevents common deficiencies in soilless media and alkaline soils.
