This report (Wheeler D and Shepherd M) was prepared for Overseer Ltd. The aim of these guidelines is to describe the information that would be required from such experiments to provide additional data for evaluating and developing the Background and Urine patch sub-models within OVERSEER. These data can be considered in terms of:
- Data that describes the experiment set-up and conditions to enable the experiment to be represented as accurately as possible by the model (e.g. climate and soils data) - inputs.
- The results that the experiment produces, e.g. measured N losses as affected by the experiment treatments (outputs) that can be used to compare with OVERSEER or aid its development.
