MI has removed the previous rice growing restrictions for season 2016/17 to open up greater opportunities for customers across the MIA. Customers are advised best management practice should apply, including growing on suitable rice approved soil types. MI will be providing RWU targets created from the Hanwood CSIRO weather station to assist rice growers to monitor rice water use throughout the season.
The 2016/17 progressive Rice Water Use (RWU) target for this season commencing 1 October to 11 January 2017, calculated using ETT and rainfall data from CSIRO Hanwood is 8.5ML/ha. The RWU target includes 2ML/ha for filling the profile, a further 2ML/ha will be added at end of season allowing for drainage/dry down.
Note 2016/17 figures progressive to 17/11/2016
Rice crop coefficient now 1.16
AWS evapotranspiration figures are now calculated using the internationally recognised FAO56 equation modified to represent tall crops ETref_t. The rice crop coefficient used in conjunction with ETref_t. Is 1.16
