Mr Freeman has been working with Mr Topham to differentially apply lime to his yellow sandy soils, which are highly acidic at depth... Tests have shown a pH as low as 4.1 in some areas... Zone 2 - Acidic gravelly sand over shallow gravel (yellow), PAWC 100 to 134mm: This soil has high aluminium toxicity and gravel increasing at depth, which results in low PAWC. Low PAWC combined with restricted rooting depth reduces plant access to water...

The decline in profitability of the high rainfall farm is driven by declining terms of trade rather than the yield reductions under predicted climate change... Farmers and advisors still require a simple method to estimate yield potential using a simple spreadsheet or 'back of the envelope' type calculations... The soil moisture values calculated by STIN XL for sowing dates later than 1 April were seen as an underestimate...

More than 1000 Australian soils have been characterised for plant-available water capacity (PAWC)... The GRDC-funded project 'Measuring and managing soil water in Australian agriculture' is working with groups of consultants and growers across the country to characterise soils for PAWC and discuss how this information can be used to inform management decisions in farm businesses... CSIRO's Canberra-based principal research scientist Dr Kirsten Verburg says when rain did not arrive in spring, growers may have underestimated the volume of water remaining in their soil following a wet start to the winter grains season...

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... Yield Prophet increased the yield prediction after grain fill but he was unsure why...

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...

Decision tool shows promise in local crop trials.. "Following a number of extremely variable seasons, many growers in the region have lacked the confidence to implement management practices to maximise yields, and have been taking an approach of 'less risk' for their in-season decision making," Mr Whisson said... Mr Whisson said the benefit of Yield Prophet to local growers over the course of the season was obvious, especially when it came to making nitrogen and fungicide decisions based on forecast yield, as well as providing side benefits such as yield estimates for insurance purposes...
