Controlled release compound fertilizer NPK 20-20-20

What It Is
 
This is a controlled release fertilizer. It contains 20% each of nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O), and is also fortified with trace elements (TE). The nitrogen promotes leafy growth and is crucial for photosynthesis as it is a key component of chlorophyll. Phosphorus is essential for root development, energy transfer, and early flowering and fruiting processes in plants. Potassium helps in regulating water balance, strengthening plant cell walls, and enhancing disease resistance. The added trace elements play important roles in various enzymatic reactions within the plants, ensuring overall healthy growth.
 
How It Works
 
The fertilizer utilizes a special technology. It is usually encapsulated with a polymer coating. When applied to the soil, water slowly penetrates the coating. As water enters, it dissolves the fertilizer inside, and then the nutrients are gradually released in a controlled manner. This release pattern is designed to match the nutrient - uptake pattern of crops during their growth cycle. For example, during the early growth stage of crops when they need less nutrients, the release rate is slow. As the crops grow and their nutrient demands increase, the release rate adjusts accordingly.
 
Advantages
 
1. High - efficiency nutrient supply: By providing a continuous and balanced nutrient supply throughout the crop growth cycle, it ensures that plants have a stable source of essential elements, reducing the risk of nutrient deficiency or over - supply. This leads to better - quality yields.
 
2. Reduced fertilization frequency: Thanks to its slow - release property, it can meet the nutrient needs of crops for an extended period. As stated on the package, it allows for "Apply Only Once, no Top Dressing", which saves farmers' time and labor costs associated with multiple fertilization operations.
 
3. Improved fertilizer utilization: The controlled - release mechanism minimizes nutrient losses through leaching, volatilization, or fixation in the soil. This not only makes the most of the applied fertilizer but also helps protect the environment by reducing nutrient runoff into water bodies.
