Product Details

NPK 15 15 15 is a type of controlled release fertilizer that contains equal amounts of nitrogen (N), phosphorus (P), and potassium (K) in its formulation. The controlled release aspect of the fertilizer means that the nutrients are released gradually over a specific period of time, typically several weeks to several months, rather than all at once. This allows for a steady and consistent supply of nutrients to the plants, reducing the need for frequent reapplication and minimizing the risk of nutrient burn. Controlled release fertilizers are often used in commercial and professional settings, such as golf courses, sports fields, and greenhouses.
