Author: DEFRA
Using this manual, issued by the Department for Environment, Food and Rural Affairs (DEFRA), will help farmers and land managers better assess the fertiliser required for the range of crops they plan to grow, by suggesting what level of nutrients are required to provide the best financial return for the farm business. The manual will help ensure that proper account is taken of both mineral fertilisers and other sources of nutrients such as manures and slurries, so helping to prevent costly over-application.
