Subsoils Innovative lime incorporation at West Wubin

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).\nLineage: The trial consists of different mixing (untreated, spaded, grizzly) with products applied (untreated, lime, dolomite and lime + dolomite). Soil water probes were installed in July 2015 in 3 replicates of the combinations of spaded and untreated mixing with nil product and lime + dolomite. 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.
