The OECD database of nutrient balances provides the latest balances for 38 OECD member countries, 5 non-OECD European Union member states and 11 emerging economies: Argentina, Brazil, People’s Republic of China, India, Indonesia, Kazakhstan, the Philippines, the Russian Federation, South Africa, Ukraine and Viet Nam. The period shown spans 1985 to the most recent data available (varies by country). The database is compiled based on annual data collection by the OECD Secretariat for some countries and via collaboration with Eurostat, which collects statistics for all EU member states plus Norway and Switzerland.
The gross nutrient balances for nitrogen and phosphorus (N and P), expressed in tonnes, are calculated as the difference between the total quantity of nutrients entering an agricultural system (mainly as fertilisers and livestock manure) and the quantity of nutrients leaving the system (mainly via uptake by crops and grassland). The nutrient balance indicator can be used as a proxy to reveal the status of environmental pressures. A positive nutrient balance represents a nutrient surplus (inputs exceed outputs), which can lead to nutrient pollution of air and water resources. A negative nutrient balance represents a deficit (outputs exceed inputs), which can lead to degradation in soil fertility. The nutrient balance indicator is also reported on a per unit land area basis, in kilogrammes of nutrients per hectare of agricultural land.
