Science webinar - Benchmarking soil amelioration outcomes using paddock yield and water use efficiency data

Join Department of Primary Industries and Regional Development research scientists Bindi Isbister and Jennifer Clausen as they share their findings on benchmarking the effect of soil improvements on crop yield using data from three grower casestudies with a history of soil amelioration.

Key messages

  • Whole paddock averages of yield, percent of yield potential achieved and gross margins can benchmark the effect of amelioration on paddock productivity.

  • Utilising spatial data layers to map yield, yield potential and gross margins can assist in identifying areas least and most responsive to amelioration. This allows targeted assessment of other constraints if a low response or indicate which soils on the farm to ameliorate if more responsive.

  • Standard yield potential estimations under-predicted achieved yields after amelioration in some soil types more than others, therefore other methods of estimating yield potential and water use efficiency after amelioration will be explored in the future.
