Project CaNE investigates sub-surface applications of mill mud

Posted by Ellie McVeigh

As part of Project CaNE’s ‘Clear As Mud’ Demonstration Program, growers across the Herbert have had the opportunity to assess various mill mud application rates and methods on their farms.

At one of the sites, the project team is investigating the sub-surface application of mill mud. Sub-surface applications can provide benefits to the grower, as well as the broader environment. This application method limits nutrient loss for the grower, as more of the applied product remains in the block after rainfall. Additionally, this reduces sediment and nutrient runoff into local waterways.

The images below have been captured at a local grower’s block. The images illustrate the application method being investigated as part of ‘Clear As Mud’.

Images below are for illustrative purposes only.

Posted by Ellie McVeigh

During August, the Project CaNE team began to harvest Demonstration sites. HCPSL staff member, Bailey Kilpatrick captured these photos whist assisting the harvester crew at one of the various demos sites across the Herbert. The team looks forward to sharing results and findings from these demonstrations with growers in the future.

This demonstration site is investigating Nitrogen Stabilisers as part of Project CaNE. To learn more about the project, visit the Project CaNE Page.

CRC Soil conference in Adelaide – HCPSL getting action on the ground.

Posted by Ellie McVeigh

The Soil CRC (for High Performance Soils) was established in 2017 to give farmers the knowledge and tools they need to make decisions on extremely complex soil management issues. It bridges the gap between soil science and farm management, ensuring that soil performance is increased not just in the short term, but in the long term. The Soil CRC brings together an elite group of industry partners, with 39 Participants, with the Australian Government contributing $39.5 million, $19.1 million from other partners and $107.7 million in-kind contributions, over a 10-year period.

The Soil CRC (for High Performance Soils) held its first annual conference since COVID-19 lockdowns, in Adelaide last week. HCPSL Company Manager- Lawrence Di Bella attended the conference with partners and associates from across Australia and New Zealand present.

HCPSL and its sister organisation Burdekin Productivity Services signed up to become Associates of the Soil CRC, with both organisations being the only sugarcane industry groups involved. Eight universities, 21 Farming Groups and other community groups from across the country were represented and are involved in the Soil CRC, tackling issues that drive industry sustainability, productivity, and profitability.

HCPSL is involved in following projects funded by the CRC Soils:

Note: Those projects reviewed by HCPSL Company Manager during the conference proceedings indicated by a *.

A number of the projects have been completed, some mid-life and some just commencing.

University staff and students are working hard on issues specific to the Herbert cane industry. Some of the notable projects that are delivering outcomes are:

This project will determine how soil performance and profitability are affected by increased crop diversity in rotational systems in both broadacre grains and sugarcane industries. The project will investigate the potential for plant-based solutions to improve soil performance through rhizosphere modification.

DISHING THE DIRT ON MICROBES

Posted by Ellie McVeigh

HCPSL staff (Company Manager Lawrence Di Bella & Project Catalyst team member Bethany Donker) recently attended a Terrain workshop on ‘Activating your Soil Microbiome’ with Dr. Christine Jones.

Dr. Jones is a highly respected ground cover and soil ecologist with global knowledge and experience in supporting landholders to understand soil health, biodiversity, carbon emissions, and the specific management of Australian soils.

Dr. Jones began the workshop by addressing the importance of any microbiome for determining the health of a system. Just as the human gut determines our own human health, the various soil microbes and endophytes in plants themselves make up the complex plant-soil microbiome which is currently best understood through DNA analysis. The microbes that make up these communities are not only communicating with plant cells and amongst themselves but also relate externally, sending and receiving messages with other plants’ microbiomes.

In addition to addressing the form and function of these different microbiomes, Dr. Jones emphasised two major factors in activating soil health: number and diversity. Not only is there a need for good ground cover but diversity in plant species and diversity in the microbiome is critical. Case studies from Germany, California and Canada with findings from long-term research trials demonstrated the relevance of these soil health principles in action for farm management. One rule of thumb is to ensure cover crops or the interrow include species from 4 different families (legumes, brassicas, forbs etc.) as this promotes microbes, improves root system development, and supports disease and drought tolerance.

Carbon cycling and storage was also briefly discussed towards the end of Christine’s presentation. New understanding of the microbial necromass (stabilised soil organic carbon) is indicating that this resource is the ‘dominant terrestrial carbon pool’ (Buckeridge et al. 2022) primarily made up of interactions from fungi and microbes with root exudates. This has implications for carbon storage in current management systems.

In addition to the main presentation, a panel of three local Tully growers spoke about their own approach to managing soil microbiomes. Practices ranging from phytophthora and nematode control with compost tea and biofert for pineapples, pest monitoring in organic red-tipped bananas and micronutrient management for tropical fruit crops provided some practical approaches to local soil management challenges and opportunities. The day ended with a tour of a tropical fruit crop farm where discussion touched on existing species diversity on-farm, potential species that might fit within the system and the different management decisions that might result from incorporating new covers into the system.
