soil water information

Catalogue: GRDC Media
Ravensthorpe grower Bevan Tuckett with an instruments station being used to map different soil types for their responsiveness to nitrogen treatments and their water-holding capacity... A SMP is permanently installed and works by sensing moisture in close proximity (about a 10cm radius) to the probe, recording this information and sending it via a cable to a telemetry unit and data logger... More than 50 SMPs have been installed in recent years across WA's broadacre cropping areas in a range of trials supported by GRDC, CSIRO, the Department of Agriculture and Food WA (DAFWA), advisers, grower groups and other industry stakeholders...

A number of tools are available to help growers measure soil water and water use efficiency (WUE), and optimise WUE... The WUE of grain production is the grain yield of a crop divided by the water used by that crop... Management tactics to lift WUE - and crop yields - were identified by the GRDC's $17.6 million national WUE Initiative 2008-13, that involved trials in all rainfall zones across WA and the rest of southern Australia...

I see the new Grains Research and Development Corporation (GRDC) 'Measuring and managing soil water' project as one of the key initiatives that will help improve knowledge about effectively using soil water information in farm decision making... Greater consistency in the different systems used to measure soil water will encourage more growers to increase their understanding of soil moisture... Management of soil water goes hand in hand with variable rate technology (VRT), which allows growers to vary input rates in different zones on their farm...

Capacitance soil water probes can provide useful information about soil water data when used with adequate professional support... Computer simulation models predict soil water information based on soil tests, soil characterisations and climate/rainfall data... Soil characterisation is about measuring the ability of the soil to hold water for use by a particular crop - or the size of the soil water 'bucket' - and takes into account potential constraints that affect the soil's ability to store water and plant's ability to extract it...

Yield Prophet , using APSIM modelling, simulates soil water, crop water use and N use on a daily basis and provides a risk assessment, through probability, of achieving a target yield.. (i) to compare soil water information provided by soil moisture probes vs. modelled outcomes from APSIM (Yield Prophet ) (ii) to evaluate soil moisture probes vs. modelled outcomes for day to day paddock management decisions.. Soil moisture probes do not provide information on soil/crop N status, and some kind of N budget is still required when deciding on whether the crop needs additional N in relation to how much water the crop has available to it...

Over recent years soil water has become an increasingly important component of crop management in Australia?s broadacre cropping systems... This project builds on previous research (GRDC CSA00011) providing more advanced soil water management training to agricultural consultants and farmers, expanding the regional characterisation of soils for PAWC and assessing technologies for the rapid characterisation and monitoring of soil water resources on-farm... The development of the Soil Water Express, provides users with the potential to undertake a rapid, but less accurate, prediction of PAWC based on locally derived soil data and functions developed from information contained in the APSoil database...

Growers have used tools to measure soil water for years but technological advances are widening the spectrum of choice... While some growers will see benefits in using higher level technologies that provide easier and more accurate real-time access to soil water information and risk management tools such as simulation modelling, others may get sufficient value from using simple devices such as the push-probe more strategically... The GRDC has funded the development of a new IOS SoilWater app by the University of Southern Queensland which gives growers access to locally specific soil water modelling to better estimate their yield potential at sowing, and make decisions ...
