Monitoring aqueous rootzone conditions under irrigated cotton and grains

Felicity Roos, at the University of Sydney, will be doing a short trial of the ‘SoluSampler’. The SoluSampler is a water sampler that collects samples at various root depths in order to monitor rootzone salinity. This tool has been used in citrus and grape crops and Felicity will be testing it for suitability for monitoring nutrient leaching and salinity levels under irrigated cotton and grains.

Aims

1. Test the suitability of SoluSampler as an in-situ sampler of rootzone conditions
2. Monitor salinity and nutrient content of sub-surface drainage under two cotton irrigation systems
3. Provide an undergraduate student field and laboratory research experience as well as greater exposure to the irrigation industry
