Economics of ameliorating soil constraints in the northern region: Spatial soil constraint diagnoses

Approximately 75% of Australian soils have single or multiple constraints that limit agricultural productivity, and in the GRDC's northern region, these commonly take the form of sodicity, acidity, salinity and compaction. Project A is part of an integrated body of work that will provide growers with tools to identify a) what constraints are present and where these occur (Project A); b) what management strategies can be used to increase yield (Project B) and profitability (Project C); and c) how strategies can be effectively communicated and demonstrated to growers (Project D).
