180~360days Coated NPK 15-15-6+4(MgO)+Fulvic acid+Amino acid+Humic acid +OM+TE Controlled Release Fertilizer

short description:

Polymer Coated NPK 15-15-6 + Additives – Premium Horticulture Fertilizer

Polymer Coated NPK 15-15-6 with 4% MgO, Fulvic Acid, Amino Acid, Humic Acid, Organic Matter (OM), and Trace Elements (TE) delivers complete nutrition for high-value horticultural crops over 180-360 days. Designed for flowers, foliage plants, palms, and nursery stock, its advanced polymer coating ensures controlled release of NPK macronutrients while organic additives enhance soil health and nutrient uptake. The formula provides balanced NPK (15-15-6) for vigorous growth, magnesium for chlorophyll synthesis, and bioactive compounds (fulvic/humic acids) to chelate micronutrients and improve root vitality. Amino acids reduce plant stress, while TE prevents deficiencies in container-grown specimens. Ideal for single-application programs in nurseries and greenhouses, it reduces leaching by 70% and fertilizer inputs by 40% versus conventional blends. Uniform 3.0-5.0 mm granules ensure even spreading in potting mixes. Customize release duration (180/240/360 days) for specific crop cycles. Achieve premium plant quality with sustained nutrition.
