Grazing experiments should be relevant to some agricultural or ecological system, actual or conceptual. They should be designed to invetigate whole systems, or parts of systems which can be isolated withot the conclusions being invalidated by interactions with other parts, unless these interactions can be evaluated in other experiments. They should ask questions which are important to biology or agriculture, and conclusions should not be too vulnerable to long-term changes which may be generated within the system. Where economic considerations are important to the applications of results, experiments should be designed to permit economic analysis. The logical structure of good grazing experiments is the same as that of other good experiments. The fact that they are sometimes complex and dificult to execute does not mean that good principles of design, analysis and interpretation are less necessary. Quite the contrary. |
