New app monitors soil water.. Soil water estimates will allow growers to better estimate their yield potential at sowing, and make decisions ... Local weather data including rainfall, temperature, solar radiation and evaporation are used to simulate crop growth, runoff, drainage and stored moisture levels in each soil layer" Dr Freebairn said...

Soil water research aids management decisions.. The soil water projects, led by Precision Agronomics Australia (PAA) and initiated by GRDC Regional Cropping Solutions Networks (RCSNs), are also likely to help growers decide whether to sow crops early or delay... Growers and consultants are invited to help test the new SoilWater App (SWApp), which has been developed under another GRDC project, led by Brett Robinson of the University of Southern Queensland...

How close a crop is to running out of available soil moisture... "PAWC is the difference between the drained upper limit (DUL), also known as the field capacity, which is the highest moisture content the soil can store before water runs off or drains away, and the crop lower limit (CLL), which is the lowest moisture content that plant roots can extract from soil," he said... "If soil moisture is above the DUL, no more water can be held in the soil so additional rain or irrigation will not be of benefit and can lead to waterlogging and surface runoff...

Soil moisture probes like any other component of precision ag can help people confirm decisions or take decision making to another level... Management decisions determining crop type, inputs such as nutrition and disease control are the ones identified where knowledge of deep soil moisture levels may assist with risk management... The objective is to demonstrate the capability of soil moisture monitoring technology with remote communication systems to display soil moisture data from key cropping regions across Victoria and determine how this information can be used by both agronomist and farmers...

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...

Using a water diviner in a maize field.. Recent efforts to improve on-farm water use efficiencies have resulted in more use of soil moisture monitoring tools, particularly capacitance probes such as C-probe, Enviroscan and Diviner... Probes are typically used to: schedule irrigations - to determine when irrigation is required calculate soil water deficit to work out how much water to apply...
