Organisation

Department of Primary Industries and Regional Development

Soil constraints cost growers in Western Australia in excess of $1.6 billion annually in lost production with most of the soils in our grain growing area being affected by one or more soil constraints.

Ranking options for soil amelioration (ROSA) is a decision support tool by the Department of Primary Industries and Regional Development intended for use by consultants, agronomists and growers to indicate soil amendment options that are likely to provide the biggest economic return for growers with multiple soil constraints.
