Treating production constraints on the sandy soils of upper and lower Eyre Peninsula locations
Aims

Why do the trial? 
There are around 5 million hectares of sandy soils under agricultural production in the low to medium rainfall areas of south-eastern Australia. These soils have multiple constraints limiting production including water repellence, soil acidity, compaction and low organic carbon levels leading to poor biological cycling and nitrogen mineralisation. Estimates of the yield gap (the difference between water limiting potential and average actual crop yield) are between 1.8 and 2.1 t/ha on Upper Eyre Peninsula and as much as 2.3 t/ha on Lower Eyre Peninsula (http://yieldgapaustralia.com .au/ maps/). 
In 2016, GRDC invested in a research program to help grain growers identify and overcome the primary constraints to poor crop water-use on sandy soils in the low-medium rainfall environment (CSP00203). The 'Sands Impacts' component of this project enables grower groups to test outcomes from the research component by applying targeted mitigation and amelioration interventions to overcome production constraints. 

Key messages

•    Production constraints on sandy soils can be overcome by mechanical intervention and the application of soil amendments, however, the response can vary between sites and years.
•    Knowledge of soil characteristics throughout the profile is vital for identifying key production constraints and determining an appropriate and effective management strategy.
