The benefits of mosaic agriculture include:
- producing fodder for on-station use,
- providing a feed buffer against dry seasonal conditions, and
- targeting cattle to a broader range of markets outside traditional selling periods for forward selling or price premiums.
Mosaic agriculture bulletin
The Department of Primary Industries and Regional Development (DPIRD) has published a comprehensive guide – Mosaic Agriculture: A guide to irrigated crop and forage production in northern WA (Bulletin No. 4915) - on growing irrigated crops and pastures within a rangeland pastoral setting. The guide is specifically aimed at Western Australian pastoralists, agronomists, agribusiness and the broader community, but many of the principles and information are widely applicable across northern Australia.
This bulletin summarises the work undertaken in DPIRD’s mosaic agriculture project, which had a particular focus on quantifying the production potential and feed quality for a range of pasture, fodder and crop options. In addition, the publication includes contributions from a range of disciplines across DPIRD (climate, soils, regulatory, irrigation, pests and disease) as well as industry and research collaborators.
This research was funded through the department’s Northern Beef Development project, in partnership with the MLA Donor Company.

Next focus areas
- DPIRD research pivot at Skuthorpe (north Broome) started in 2020. The focus is on:
- Monthly production and feed quality of a range of warm season perennial grasses
- Nitrogen balance of irrigated Rhodes grass pastures
- An annual cropping system with a maize variety trial over the 2021 dry season
- Refining weed risk assessments for non-indigenous species to inform policy
- Weed risk field nursery trials were established in four key environments to assess the environmental weed risk posed by non-indigenous agricultural plants.
- The feasibility of developing a sterile leucaena variety. Leucaena is a leguminous that provides high quality cattle feed, however it can also be an environmental weed in some situations.
