soil water level

Catalogue: GRDC Updates
We can do little to control the amount of water the crop receives... N budgets have been used to estimate required crop N demand for a long time... Using this as a starting point, we can estimate the amount of N needed to grow the whole crop...

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...

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 ...
