subsoil constraints

Catalogue: GRDC Media
Subsurface acidity is a major constraint to crop and pasture productivity across Western Australia's grainbelt and is estimated to erode potential crop yields by 9 to 12 per cent, worth $500 million annually... About 14.25 million hectares of WA grainbelt soils are acidic or at risk of becoming acidic to the point of restricting crop yields, and lime use has increased in recent years to address acidic soils with low pH levels... Useful information for grain growers about subsurface acidity and liming is available in a Grains Research and Development Corporation (GRDC) Soil Acidity in WA Hot Topic, available at www.grdc.com.au/SoilAcidityWA ...

Constraints which limit cropping productivity in the southern cropping region (Victoria, South Australia and Tasmania) will be tackled through a suite of new projects to be funded by the Grains Research and Development Corporation (GRDC)... Through its 2016-17 External Investment Plan, the GRDC is seeking research partners to undertake a range of programs aimed at providing grain growers with the technologies and practices they require for their businesses to remain profitable... "The 2016-17 External Investment Plan will address identified gaps in research, development and extension, and it will complement the GRDC's previous and existing investments in RD&E," Mr Pengilley said...

Subsoil manuring comes of age in HRZ.. "What we end up getting after subsoil manuring is a larger bucket size and soil capable of holding three times its original capacity of plant-available water, which can be stored deep in the profile to be used in the spring grain-fill period achieving much higher water use efficiency.".. While results are still inconclusive as to which manure or organic matter might be best to use, Dr Peries says they do need to find a material that is more abundantly available should the popularity of subsoil manuring increase...
