In this podcast episode, results from Anthony Rowe’s vari-rate and sowing time demonstration in Millewa are discussed. Pete Treloar and Anthony Rowe talk about the outcomes presented to the Millewa agronomy group, focusing on the benefits of increasing seeding rates on sandhills for crop yield and ground cover, and the mixed results on different soils.

Despite the underwhelming response to reduced rates on heavy soils, the importance of seed over fertilizer was highlighted. The discussion also explores the role of phosphorus in vari-rate fertilization, the prospects of further optimization in seeding and fertilization strategies, and the usage of EM38 mapping for soil analysis.

Anthony mentions a sowing time trial showing significantly better yield for crops sown earlier, reinforcing the value of early and optimal sowing times.

The project, supported by the Mallee Catchment Management Authority through the Australian Government’s Future Drought Fund, underscores advancements in agricultural practices aimed at bolstering profitability and sustainability in the face of drought.
