A range of compound fertilizers with a combination of nitrogen, phosphorus and potassium (NPK) – the most essential plant nutrients – which help to maximize crop yield and quality is called Straight NPK Fertilizer. Each compound, whether in prill or granule form, is designed to meet the average crop requirements.
Some NPK fertilizers also contain secondary and micronutrients 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.
