Adding a Management

Managements refers to something that occurs at a specific time and has a quantity; Managements include actions that are done to a plant or ecosystem, for example the planting density or rate of fertilization. Managements are distinct from Treatments in that a Treatment is used to categorically identify an experimental treatment, whereas a management is used to describe what has been done.

Managements are the way a treatment becomes quantified. Each treatment is often associated with multiple managements. The combination of managements associated with a particular treatment will distinguish it from other treatments. The management types that can be entered into BETY are described in tab:mgmttype.

Each management may be associated with one or more treatments. For example, in a fertilization experiment, planting, irrigation, and herbicide managements would be applied to all plots but the fertilization will be specific to a treatment. For a multi-year experiment, there may be multiple entries for the same type of management, reflecting, for example, repeated applications of herbicide or fertilizer, for example see fig:trtmgmt.

note: At present, managements are recorded for Yields but not for Traits, unless specifically required by the data or project manager.

Figure 7: Form for entering new managment
Image management_new Form for entering management data with example data. This management denotes a nitrogen fertilization rate of 112.0 kg N ha-1.

To associate a management with multiple treatments, first create the management, then edit the management and add treatment relationships.

mgmttype
the name of the management being used. A list of standardized management types can be found in tab:mgmttype.
Level
a quantification of mgmttype.
units
refers to the units of the level. Units should be converted to those in tab:mgmttype.
dateloc
date level of confidence, explained in sec:traits and defined in tab:traits.
