Once a trial has been established in a field, the quality of the results depends on the quality of the data collected. There are two types of data that are important, first the data taken to directly describe treatment differences, and second type called metadata that puts the direct data in context to better explain the results. Metadata includes weather, time of application, soil properties, etc., which can help explain results and enable future comparisons.
