Global potassium fertiliser consumption |
 |
 |
 |
|
The main potassium fertiliser source is potassium chloride (KCl), followed by potassium sulphate (K2SO4), and potassium and magnesium sulphate double salts (K2SO4.MgSO4). Potassium nitrate (KNO3) accounts for only 2 % of the total global potassium fertiliser consumption, expressed in K2O units (Table 1).
