About this data
The Fertilizers by Nutrient dataset contains information on the totals in nutrients for Production, Trade and Agriculture Use of inorganic (chemical or mineral) fertilizers. The data are provided for the three primary plant nutrients: nitrogen (N), phosphorus (expressed as P2O5) and potassium (expressed as K2O). Both straight and compound fertilizers are included.
