NIR Tissue Test

Summary

Over 35% of rice crops in NSW have their nitrogen status assessed during the panicle initiaton growth stage by the SunRice NIR Tissue Test Service to determine nitrogen topdressing rate recommendations. This service and numerous rice research projects utilise accurate sample analysis provided by the Bruker FTNIR instrument at a low cost compared to conventional laboratory analysis. The maintenance of the NIR instrument and annual update of the numerous rice shoot, grain and straw nutrient calibrations is essential to the success of these projects. This project will maintain the Bruker FTNIR instrument and update the rice shoot panicle initiation tissue nitrogen calibrations yearly covering the range of rice varieties grown, maintaining samples from over 10 seasons and covering the range of nutrient concentrations. We will work with SunRice ensuring the Tissue Test Service proceeds smoothly during the testing season and accurate results are provided to growers. Calibrations for ground paddy grain, ground white grain and ground straw nitrogen concentrations will also be maintained and updated yearly and samples from other rice research projects will be analysed.

Objective Summary

To maintain the Bruker FTNIR instrument and the rice shoot, grain and straw calibrations. Ensure the instrument is providing accurate plant nitrogen results and growers receive quality nitrogen topdressing rate recommendations. Provide NIR analysis support to other rice research projects.
