The innovative use of electromagnetic (EM) technology is enabling Moree district cropping manager Byron Birch, Rimanui Farms, to proactively manage his production risk by accurately matching crop selection with soil moisture availability... Mr Birch uses a mobile EM38 device to take soil moisture readings across dryland black cracking clay paddocks to generate a comprehensive analysis of soil moisture availability... "The EM38 has the ability to give a tangible figure which can be inputted into a spread sheet much like the probes and it can be used in conjunction with push probes, neutron probes and capacitance probes to verify readings."..

Real-time moisture tracking sharpens yield predictions.. "Using French-Schultz to estimate yield has given us the confidence to market a bit more of our grain before harvest if seasonal conditions are favourable, especially if we can use the probe and Yield Prophet to double-check the results," Anna-Lisa says...

Results from technology that measures soil moisture across the Western Australian grainbelt indicates that nitrogen fertiliser 'top-ups' applied in coming weeks could have variable yield benefits, depending on location... "Analysis of sites hosting new soil moisture probes suggests that potential benefits range from nil to more than 0.5 tonnes per hectare," Precision Agronomics Australia's Frank D'Emden said... " the modelling suggested that responses to top-up nitrogen ranged from nil at the Beacon, Bonnie Rock, Southern Cross and Merredin sites - where soil moisture is marginal - to at least 0.5t/ha at the Coomberdale, Bindi Bindi, Dowerin, Lake Grace and Jerramungup sites - where soil moisture levels are reasonable," he said...

Tom Robinson says data from soil moisture probes has helped determine target yields on his family's property at Halbury, South Australia... Mr Wilksch, who specialises in the installation and management of soil moisture probes, says the probes have extremely accurate sensors every 10 centimetres, which tell the grower where the moisture is in the soil profile and from where the plant roots are actively drawing moisture... Mr Wilksch says the three management areas in which probes help decision-making are when and what to plant, nitrogen and other nutrient decisions, and during spring when it is possible to estimate yield based on the amount of plant-available water in the profile...

Data from soil moisture probes is being used with Yield Prophet modelling to improve soil-type characterisations.. Mr D'Emden says initial results from the 2014 probes showed that half of the GS30 (June/July) Yield Prophet estimates were within 300 kilograms per hectare of the final crop yield, increasing to 70 per cent within 300kg at GS90, with a median difference between the Yield Prophet GS90 estimates and final yield of 0.35t/ha... The total PAW estimates require further calibration to account for the influence of subsoil constraints such as salinity, sodicity or acidity...
