Straight fertilisers are those fertilizers that primarily contain only one primary nutrient essential for plant growth. These nutrients are nitrogen (N), phosphorus (P), and potassium (K), often referred to as N-P-K. Examples of straight fertilisers include urea ammonium sulphate, ammonium nitrate, superphosphate and muriate of potash (potassium chloride)

These straight fertilisers are often used alone or in combination to meet the specific nutrient requirements of different plants and soils.

Types of Straight Fertilisers

  • Urea (46-0-0)
  • Ammonium Sulphate (21-0-0-24S)
  • Triple Superphosphate (0-46-0)
  • Monoammonium Phosphate (MAP) (11-52-0)
  • Diammonium Phosphate (DAP) (18-46-0)
  • Muriate of Potash (0-0-60)
