This fertilizer is a combination of controlled release nitrogen, phosphorus, potassium and chelated microelements, which is designed for spring application to maximize foliage and germination. Approximately 35% of the nitrogen is immediately available for budding and leaf growth and remaining nitrogen is gradually released until late summer which leads to stronger root systems in plants. It is a homogenous granular fertilizer which contains precisely a balanced ratio of nutrients needed by the plant.
Applications and usage
- This water-insoluble granular fertilizer is suitable for greenhouse plants, flowering trees, shrubs, vines and fruit trees in spring.
- For fruit trees, 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.
