Co-developing and improving digital tools for increased drought resilience with, and for Tasmanian farmers

GrassGro parameters were examined for ryegrass, phalaris, cocksfoot and tall fescue. The model results were compared with actual production, primarily using measured pasture production in the Pasture Variety Trial Network. Ryegrass and phalaris are well established in the GrassGro model and no modification is required for these. Cocksfoot has been available in the GrassGro model and there is generally a good relationship between actual and modelled results, although some minor changes in parameters have been suggested for come cultivars of cocksfoot. Tall fescue was not previously activated in the model, although a set of suggested parameters has been available. These were tested and no change in those parameters was required, so this pasture species can be activated in GrassGro

The recommended changes have been included in the December 2023 release of GrassGro and can be made available for users of Farming Forecaster.

A set of probe sites in Tasmania have been selected and are being examined using 100 years of weather data, to ensure that the current pasture used at those sites gives consistent result sin GrassGro and to examine whether the use of cocksfoot or tall fescue would provide any benefits, particularly in drought periods.

Interviews with farmers found that many producers find technology difficult, and although small groups are able to use the technology, they prefer face-to-face training, preferably with the same trainer. This is seen as the best option for developing the skills required to use Farming Forecaster effectively.
