These generally include areas with:
- low frost risk with adequate warmth during the growing season
- well-drained soils
- neutral to slightly acidic pH range.
The crop rules show which areas have the best or worst conditions for particular crops or enterprises according to a suitability classfication system (refer to inset image for class ratings).
The rules also show if there are opportunities to improve conditions.
The crop rules were developed in collaboration with the Tasmanian Institute of Agriculture (TIA) and industry consultation using existing guidelines, literature, and research data, and presume adequate irrigation is available.
There are 3 types of enterprise suitability maps available pertaining to each crop based on:
- Current climate (to 2018)
- Climate Futures for Tasmania projection modelling (to 2030 and 2050).
How to Use Enterprise Suitability Maps in LISTmap
When viewing the maps in LISTmap, information can viewed by clicking on any area of the map (ensure the relevant crop is 'ticked' within the Layers/Add Layer panel – refer to Figure 1 for an example).
A pop-up box identifies information such as the 'Overall Suitability Rating' as well as other useful information including:
- 'Constraints' - provides a list of attributes that limits a classification to a particular suitability rating.
- 'Manageable Constraints' - provides a lists of soft limitation attributes that should be managed to meet the suitability rating.
Detailed instructions on how to access, view and use the Enterprise Suitability Maps on LISTmap are availble LIST map instructions (69Kb)
Additional information for assisting in site selection for each crop are found in the fact sheets (refer to Table 1).
