100%
  • P = P2O5 × 0.44
  • P2O5 = P × 2.29
  • K = K2O × 0.83
  • K2O = K × 1.21
  • 1 tonne = 1,000 kg
  • 1 ha = 10,000 m2

Using the conversions above calculate : 

  1. How much N, P and K are in a 15 kg bag of 0-46-0? 
  2. How much N and P2O5 are in half tonne of DAP (18-46-0)? 
  3. How much P and N are in quarter tonne of DAP (18-46-0)?
