New Murchison region discussion group to help farmers improve soil water use

New Murchison region discussion group to help farmers improve soil water use

Riverine Plains is pleased to announce it is coordinating a new project which involves the establishment of a new discussion group for farmers in the Murchison district of Victoria.

The Improving Soil to Optimise Water Use On Farm project is funded until 2023 by the Australian Government through the Future Drought Fund Natural Resource Management Drought Resilience Program – Grants, and aims to address soil quality parameters and how these are linked to storing more rainfall for crop production.

Riverine Plains Project Officer, Kate Coffey, explained that soil quality parameters such as pH, CEC and soil organic carbon can affect how much moisture is stored in soils, with healthier soils being more likely to be able to store moisture for later use, such as during a dry spring.

“The first step in improving a soil’s ability to store moisture is understanding the constraints present in the soil and this can be done using yield and EM38 mapping, followed by soil testing to ground-truth or confirm the presence of the soil limitation” said Ms Coffey.

“Once a constraint, such as subsoil acidity, has been identified it can then be managed through lime application or other methods to improve crop production and profitability” added Ms Coffey.

The project aims to increase awareness and knowledge around the identification of key local constraints, such as sub-soil acidity, and also involves the demonstration of innovative methods that protect and manage the soil resource.

To this end, a local trial will be established to demonstrate stubble management as a tool to improve soil moisture retention, with the trial also acting as a focus for the discussion group through local field days and workshops.

“Overall, the project will provide farmers with a better understanding of their soils and knowledge of how soil can be managed to improve production and water retention, which will ultimately help improve resilience for future droughts” concluded Ms Coffey.

Hyper Yielding Crops meeting – key points from 23 February meeting

Riverine Plains hosted Hyper Yielding Crops project meetings at Brocklesby and Rutherglen on Tuesday 23 February, 2021. Results from the Hyper Yielding Crops On-farm Focus Trials, as well as the results from the Hyper Yielding Crops technology centre at Wallendbeen were discussed, with presentations by Nick Poole and Tom Price (FAR Australia), Jon Midwood (TechCrop) and Kate Coffey (Riverine Plains).

More detailed results and information from the Hyper Yielding Crops field day are available by downloading the following presentations NSW HYC Grower meeting 23 Feb 2021 and 210223_HYC RP Innovation Groups

Key points from the On-farm Focus trials were;

Nitrogen trial, Howlong (Accroc wheat)

  • There were clear differences between the northern and southern parts of the paddock, based on the old fence line. The differences could be paddock history, soil type or past management or all of the above.
  • In the northern half of the paddock, there was a negative yield response to extra 100kg/ha urea (46kg N/ha) at GS30 in the strip trial. Yield decreased by 0.45t/ha and gross margin loss was $147/ha.
  • On the southern half of the paddock, the addition of 200kg/ha urea (92kgN/ha) at GS30 produced an extra 0.55t/ha, compared to the Nil urea at GS30 strip to the south. This gave break-even situation.
  • Grain protein (N content of the grain) of the highest yielding strip was only 8.3%.  With different N timings maybe the highest yielding treatment could have been even higher?

Fungicide trial, Culcairn (Trojan wheat)

  • Based on this trial, if stripe rust was left uncontrolled,  yield loss was up to 4.0t/ha.
  • Cogito at GS30, Prosaro at GS32 and Opus at GS39 gave the highest, significant (p<0.05), yield of 7.67t/ha. The additional gross margin from the application of fungicide was: $800/ha.
  • If farmers continue to grow susceptible varieties such as Trojan and Bennett, adding flutriafol on the fertilizer gives the grower significant improvement in levels of control. Fungicides will still be required at GS32 and GS39.

Nitrogen trial, Gerogery (HyTTec canola)

  • Based on this trial, an additional 80 kg/ha of urea at the yellow bud stage gave a significant (p=0.005) yield advantage over the overall paddock strategy. The gross margin of the additional applied nitrogen was $29/ha.
  • Increasing the rate of urea at yellow bud to 160 kg/ha urea didn’t increase yield significantly.
  • To optimize yield,  aim for a target flowering dry matter of 5t/ha. The trial reached this optimum amount of dry matter at flowering. Hybrids offer the potential for higher and more resilient yields over the open pollinated varieties.
