Canola seed, dryland, W Downs {AU-NSW}| canola seed production | AusLCI, U
Unit process v00.00.000
This dataset represents the production of 1 kg of canola. The yield is 1589 t/ha. Documentation for this dataset can be found in the 'LCAgMetrics Methodology for developing Life Cycle Inventory' report, available at https://agrifutures.com.au/. (Hume, I., Renouf, M.A., Eady, S.J., Grant, T., 2025). It was developed as part of the LCAgMetrics project, a partnership between Agrifutures Australia and Lifecycles, funded by the Australian Government’s Sustainability Reporting Uplift Grant as part of the National Agriculture Traceability Grants Program. Production Volume: 52277 t/yr. Activities included: This activity starts after the harvest of the previous crop. Activities included are: the inputs of seeds, mineral fertilisers, pesticides and irrigation water, all machine operations and corresponding machine infrastructure and sheds. It is assumed that no organic fertilisers are applied. Machine operations are: soil cultivation, sowing, fertilisation, irrigation, weed control, pest and pathogen control, combine-harvest, and drying of grains. Direct field emissions are included. This activity ends after harvest and drying of grains at the farm gate. Energy values: 28.8MJ/kg (gross). Nutritional values: Protein: 21%. Carbohydrate: 0%. Fat: 46%. Geography: Western Downs and North West Slopes and Plains, NSW, AU. Technology level: Represents current practices as per gross margins reports (AgMargins 2024 & SA Gross Margin Guide 2022). Time period: 2017-2021.
