Increasing adoption of new techniques combining physical, chemical and plant based interventions to improve soil function on Eyre PeninsulaTrials and demonstrations involving soil mixing either with a spader or ripping with inclusion plates have been shown to increase yields on sandy soils on Eyre Peninsula (EP). Many of these trials have included the addition of organic material incorporated at rates of 5-10 t/ha. Whilst generally these treatments have provided yield increases for a number of years post application, the rates applied have proven to be uneconomic (EPFS 2019, p 71). This project was originally developed by the Lower Eyre Ag |

Controlled traffic farming effects on soil emissions of nitrous oxide and methaneSoil compaction affects soil aeration and gas diffusivity, and thus has a major impact on the release of greenhouse gases (GHGs) from fertilised soils. Controlled traffic farming (CTF) systems reduce the area of compacted soil by confining all field traffic to permanent traffic lanes, and a pilot trial at one long-term CTF site provided evidence of reduced soil emissions. We investigated the effect of CTF on soil emissions of nitrous oxide (N2O) and methane (CH4) using replicate manual chamber measurements in 3 traffic treatments;namely:non-trafficked CTF beds, permanent CTF lanes,and a single traffic pass on CTF beds to simulate the random traffic tracks of non-controlled traffic farming. Emissions of N2O and CH 4 were monitored from these treatments in 15 crops over 3 years on 6 grain farms in Queensland, Victoria and Western Australia. Thus, the major objective was to determine the emissions of N2O and CH4 from random trafficked and permanent traffic lane soil, relative to those from non-trafficked CTF beds. These emission ratios are referred to here as traffic impact factors. |

Non-wetting management options (West River - Burrell)Claying has been undertaken in many areas throughout the zone, and there is quite a bit of expertise on the risks and benefits associated with it within the zone. Cash flow of most farmers in general doesn’t allow the expense of the high rates of clay to occur. However, there is anecdotal evidence to suggest that low rates of clay (lower than rates used currently to improve soil structure) will improve the wettability of the soil. By including clay in the trial it is anticipated that the benefits of low rates of clay will show improved wettability. Other opportunities for the zone appear to be mitigation of non-wetting – including on-row seeding. This would include associated practical risks around seeding such as stubble handling issues and accurate seeding systems. |
