90~180days Coated NPK 9-9-9+9(Fulvic acid)+Humic acid +OM Controlled Release Fertilizer

short description:

Polymer Coated NPK 9-9-9 + 9 percent Fulvic Acid – Organic-Enhanced Horticulture Fertilizer

Polymer Coated NPK 9-9-9 with 9 percent Fulvic Acid, Humic Acid, and Organic Matter (OM) provides balanced nutrition for flowers, nursery plants, and horticultural crops. Designed for 90-180 day controlled release, its polymer coating ensures gradual nutrient delivery while high fulvic acid content maximizes bioavailability. The 9-9-9 NPK ratio supports root development, foliage growth, and flowering. Nine percent fulvic acid enhances nutrient transport and chelates micronutrients, working synergistically with humic acid to improve soil structure and water retention. Organic Matter boosts microbial activity in growing media. Ideal for container production and nursery beds, this formula reduces salt stress by 40 percent and leaching by 55 percent versus conventional fertilizers. Uniform 2.5-4.0 mm granules allow even distribution in potting mixes. Suitable for seasonal applications in bedding plants, perennials, and young transplants, it eliminates frequent top-dressing and cuts labor costs by 30 percent. Customize release duration (90/120/150/180 days) for specific growth cycles.
