Using bore water on rice

Rice growers using groundwater on their crops need to plan ahead to minimise the negative impacts of the water salinity. In particular, they need to:

  • Have constant access to a properly calibrated salinity meter to monitor the salt content of the water;

  • Set up their layouts so that water circulates (i.e. alternate stops);

  • Know the salinity limits for each rice growth stage;

  • Be willing to drain water from the block once thresholds have been exceeded, especially between P.I. and young microspore.

  • Plan for the crop water use to increase (as saline water moves more readily through soil than fresh water).
