Sandy Soil Validation Trial: Sandy Soil Project CSP00203 – Sandy Soil Amelioration & Mitigation Practices (year 3)

The GRDC funded Sandy Soils project (CSP00203) is a collaboration between CSIRO, University of South Australia, Primary Industries and Regions SA, Mallee Sustainable Farming Inc, AgGrow Agronomy and Trengove Consulting.

The validation trials are part of the sandy soil project and they aim to validate the outcomes of the Sandy Soils Research Program across the south-eastern region, enabling targeted mitigation/amelioration techniques to be tested or demonstrated to overcome diagnosed primary/secondary constraints on sandy soils. In 2021 the trial set up in 2019 will be further monitored. This is the final year of the trial.

The trial at Monia Gap is looking at the use of deep cultivation approaches, including the use of a spader, on sand hills to provide better crop uniformity and performance as well as the impact of gypsum and manure on crop performance, in addition to cultivation alone. In 2020 it is sown to canola. The 6 treatments include:

  1. Control (district practice)
  2. Ripped (60-70cm) and Spaded
  3. Spaded
  4. Spading plus 1.5 t/ha Gypsum
  5. Spading plus 2.5 t/ha Manure
  6. Spading plus 2.5 t/ha Manure & 1.5 t/ha Gypsum
