About this data
The Cropland Nutrient balance domain contains information on the flows of nitrogen, phosphorus, and potassium from mineral fertilizer, manure applied, atmospheric deposition, crop removal, and biological fixation over cropland and per unit area of cropland. The flows are aggregated to total inputs and total outputs, from which the overall nutrient balance and nutrient use efficiency on cropland are calculated. Statistics are disseminated in units of tonnes and in kg/ha, as appropriate. Nutrient use efficiency is expressed as a fraction (%).
