Descripción
The FAOSTAT domain “Soil nutrient budget” disseminates nutrient flows in a given country and year. The soil nutrient budget can give an indication of nutrient use efficiency, as it can help quantify excess nitrogen leading to environmental risks, for instance, GHG emissions or pollution from volatilization and leaching/runoff. It can also signal soil nutrient deficits that limit crop production. This analytical brief focuses on the nutrient nitrogen. Nutrient budgets are presented both as total nutrient flows and per area of cropland. Global and regional trends are analyzed along with highlights of the most important contributors to the overall budget and how these main contributors have changed over time. Lastly, the top 10 countries for the soil nutrient budget per unit area and bottom 10 countries for the soil nutrient budget total are presented.
