NPK fertilisers

• NPK fertilisers - Nitrogen, Phosphorus and Potassium. substance that is applied to soil, in order to supply plants with nutrients
• 3 fertilisers:

  • ammonium nitrate
  • ammonium sulphate
  • ammonium phosphate
• Ammonium nitrate:

  NH3 + HNO3 -> NH4NO3
• Ammonium sulphate:

  2 NH3 + H2SO4 -> (NH4)2 SO4
• Ammonium phosphate:

  3 NH3 + H3PO4 -> (NH4)3 PO4
• Nitrogen is crucial for leafy green growth and chlorophyll
• phosphorus promotes strong root development and flowering
• potassium supports overall plant health
