A range of compound fertilizers with a specific combination of nitrogen, phosphorus and/or potassium (NPK) – the most essential plant nutrients – that helps to maximize crop yield and quality is called Straight NPK Fertilizer. Each compound, whether in pill or granule form, is designed to meet the average crop requirements.
Some NPK fertilizers also contain secondary nutrients and micronutrients (trace elements) essential for specific needs. These may include magnesium (Mg), sulphur (S), boron (B), iron (Fe), manganese (Mn), molybdenum (Mo), and/or zinc (Zn). These formulations benefit the grower because they provide even distribution of nutrients, whether spread by hand or machine. There is no risk of nutrient segregation during shipping, handling, or spreading.
