This fertilizer is a combination of controlled release nitrogen, phosphorus, potassium and chelated microelements, which is designed to maximize plant yield and quality. This fertilizer supplies a balanced nitrogen source, containing nitrate-N for root development, ammonium-N for sustained feeding and urea-N for improving the quality of the plant. It is a homogenous granular fertilizer which contains precisely a balanced ratio of nutrients needed by the plant. The elements of this fertilizer are released gradually into the soil and are completely absorbed by the roots of the plant without wasting through leaching. High potassium content of this fertilizer is absorbed gradually by the roots of the plant and accelerates grain germination and leaf growth.

Applications and usage

  • This water-insoluble granular fertilizer is suitable for greenhouses, flower pots and all types of agricultural and horticultural plants. It is applicable in all seasons.
  • In horticultural plants, it should be added before buds emergence via digging 2 – 4 holes (30×40 cm2) under tree shade. In farms, it can be added to soil while plowing the land. In ornamental plants and greenhouses, it is mixed with planting bed.
  • Application rates are for guidance only. Actual rates will vary with local growing conditions, soil analysis and plant’s age.
  • It is compatible with most types of fertilizers and pesticides.
