Subsoil constraints- Dandaragan


CSIRO aims to identify the differences in water uptake patterns by crops for constrained (acid and compacted) and ameliorated (limed, ripped, lime and ripped) treatments. To determine if the water patterns and yields in the trials can be estimated (using APSIM) through adjustments of the soil’s root growth (xf).

Soil Water Content Lime


The trial consists of control and 7 different mixing treatments with lime applied at 0, 3and 5 t/ha. Soil water was monitored with FDR probes, which were installed in August 2015 in 3 replicates of the combinations of rip+spaded and untreated mixing with nil product and 5 t/ha lime. In each plot, measurements of pH, soil strength, crop biomass, crop yield, weeds were collected as well as drone images of NDVI over the trial. This data was used to infer effect of acidity and compaction with amelioration strategies on the crop yield and soil water uptake and compare APSIM modelling.


Thanks to Peter Negus for use and access to his property. This trial was set-up in 2013 by the West Midlands Group (WMG) funded by GRDC through the Western Agribusiness Trial Extension Network. The establish, manage and monitor this trial in 2013 by David Gartner and Peter Negus (WMG), Trevor Bell, Steve Cosh, Gavin Sarre and Breanne Best (DPIRD); Joel Andrew (Precision SoilTech). Stephen Davies and Chris Gazey’s involvement was supported by GRDC and DAFWA through DAW00204 ‘Delivering agronomic strategies for water repellent soils in WA’ and DAW00236 ‘Soil Acidity is limiting grain yield’ respectively. In 2015-2019 the trial management & data collection were funded by GRDC through DAW00242: Subsoil constraints - understanding and management which was led by David Hall (DPIRD) and Yvette Oliver (CSIRO). This data set was contributed by Yvette Oliver, Phil Ward (CSIRO), Karen Treble (CSIRO), Chris Wilkins, Nathan Craig (WMG). The CSIRO project team also included Mike Wong and Gary Ogden.

About this Project

GRDC/WAAA: DAW00242 Subsoil Constraints


Subsoil constraints (SSC) cost WA growers more than $600 million pa in lost production (Herbert 2009). The constraints include subsoil: Acidity, nutrient disorders (deficiencies, toxicities), compaction, sodicity/ waterlogging/permability contrast and alkalinity/boron/transient salinity. These constraints reduce root depth and function to the exten... more
