180~360days Coated NPK 12-6-27+4(MgO)+Fulvic acid+Amino acid+Humic acid +OM+TE Controlled Release Fertilizer

short description:

Polymer Coated NPK 12-6-27 + Additives – High-Potassium Tree Fertilizer

Polymer Coated NPK 12-6-27 with 4 percent MgO, Fulvic Acid, Amino Acid, Humic Acid, 8 percent Organic Matter (OM), and Trace Elements (TE) provides optimized nutrition for mature palm trees, fruit trees, and perennial horticulture crops. Designed for 180-360 day controlled release, its polymer coating ensures gradual delivery of high-potassium (27 percent K2O) to enhance fruit quality, drought resistance, and sugar accumulation. The formula includes 4 percent magnesium oxide for chlorophyll synthesis and 6 percent phosphorus for energy transfer, while organic additives improve soil structure and nutrient uptake efficiency. Bioactive components (2 percent fulvic acid, 3 percent humic acid, 1.5 percent amino acids) reduce environmental stress and chelate micronutrients. Ideal for single-annual-application programs, it cuts leaching by 65 percent and salt index by 30 percent versus conventional fertilizers. Uniform 3.5-5.0 mm granules ensure even distribution in root zones. Customize release duration (180/240/300/360 days) for crop-specific needs. Optimize yield and quality in high-value tree crops with reduced input costs.

KEY BENEFITS
1. Fruit Quality Enhancement
27 percent potassium improves brix, color, and shelf life in fruit crops.

2. Drought Resistance
Humic acids increase water retention; potassium regulates stomatal closure.

3. Magnesium Synergy
4 percent MgO prevents leaf chlorosis in high-light environments.

4. Nutrient Efficiency
Polymer coating reduces potassium leaching by 65 percent in sandy soils.

5. Soil Health
8 percent OM boosts microbial activity in tree root zones.

APPLICATION GUIDE FOR MATURE TREES

Crop Type	Ideal Duration	Application Rate
Mature Palm Trees	300-360 days	1.5-2.0 kg per tree
Citrus Fruit Trees	240-300 days	1.0-1.5 kg per tree
Mango/Avocado	240-300 days	1.2-1.8 kg per tree
Vine Crops (Grapes)	180-240 days	800-1000 kg per hectare

COMPOSITION ADVANTAGES

Low Phosphorus (6 percent P2O5): Minimizes runoff risk in mature orchards.
Amino Acids (1.5 percent): Mitigate heat/cold stress during fruiting.
TE Package: Corrects common deficiencies in calcareous soils (e.g., iron chlorosis).
