The leaflet gives practical guidance on using data and calculating farm-gate nutrient budgets with sections on soil analysis, nutrient inputs, nutrient losses and flows, nitrogen fixation through leys and how inputs and outputs from organic manures and livestock feed can be recorded. It contains one example table of a farm-gate annual nutrient budget for a mixed cattle and arable farm.
The tool is specific to organic farming. It was drafted for the UK but has relevance in other countries
