Reads external grass production database for pasture production

The Data reader components are used to read external data for use by CLEM. They can be placed anywhere within the simulation branch of the APSIM simulation. It is recommended to place them with the activities using them or below the CLEM component.

This Data reader is used to read a pasture production data cube in Microsoft Access format. The database contains the results of pasture production simulations for a given historic period across a range of land conditions, grass basal areas and stocking rates.

This is an advanced feature for modelling pasture (e.g. properties in northern Australia). Expertise is required to produce the lookup database with output from a pasture model. Contact the CLEM team to discuss using other models to provide pasture production.

The following parameters are used to define this component

The name of the ASCII file containing the data including extension. Include the full path of the file if not contained in the same folder as the APSIMX file.

TThe specified file cannot be open some other applications (e.g. Excel) when you run your simulation.

The column of the database must include

Id specifying the region (Region). This must relate to the region index used in the CLEM component.

Id specifying the soil type (Soil). This must relate to the soil type index used in the Land type.

The id of the forage (ForageNo).

The Grass basal area (GrassBA) at the time of production.

The Land condition index (LandCon) at the time of production. This is tracked by the ecological indicators section of Manage pasture

The Stocking rate (StkRate) at the time of production.

The year of production. This links production data with rainfall.

The month of production. This links production data with rainfall.
