The Australian processing tomato industry operates in a global market, where good environmental credentials are important in achieving the best financial returns for growers.
In a recent project, AHR has worked with the Australian processing tomato industry to develop ways of reducing environmentally harmful nitrous oxide emissions.
The findings of the project are outlines below, and a how-to fact sheet has been produced to provide more detail on how growers can minimise nitrous oxide emissions.
- The growing practices currently used by the Australian processing tomato sector generally produce low nitrous oxide emissions
- Crop establishment is the greatest risk period for nitrous oxide emissions
- Water and nitrogen management are the key to managing nitrous oxide emissions during planting and throughout the growing season
- Applying a greater proportion of the nitrogen fertiliser via trickle irrigation, and less as a basal fertiliser helps reduce nitrous oxide emissions
- Metham sodium application prior to planting reduces nitrous oxide emissions by killing soil microbes
- Adding organic matter is great for the soil condition, but it does increase the risk of nitrous oxide emissions.
