Break crop selection in low rainfall environments: one size does not fit all – WA, SA, VIC, TAS, NSW (Factsheet)
This Grain Research and Development Corporation (GRDC) factsheet explores strategies to incorporate break crops in crop rotations in low rainfall systems in South Australia.#
The results highlight that break crop selection should be based on a whole-of-system approach. Decisions depend on the purpose of the break (such as weed control or nitrogen supply), end-use, financial risk, paddock conditions, and soil type.#
Trials conducted from 2017 to 2019 across multiple sites evaluated a range of break crop species and varieties, including canola, pulses, and vetch, with options for grain, grazing or hay. While some high-performing varieties were identified, no single option suits all situations.#
Overall, the findings emphasise that the success of break crops depends on matching species and varieties to local conditions and farming system constraints, including soil type, herbicide residues, and weed pressure. While the study was conducted in South Australia, it is relevant to low rainfall farming systems across Southern Australia.#
This is a carefully curated database of important soil resources. The data base is not exhaustive but rather a library of the resources we believe are the most useful for the audience. Each resource has been added after careful consideration against our selection criteria, including but not limited to its scientific validity, accessibility, and readability. The library generally does not include most academic research papers but may include some open-source papers written in accessible English.
