As part of the recent focus on mill by-products, HCPSL Project CaNE and Project Catalyst staff toured Victoria Mill to develop a stronger understanding of the mill’s operation and generation of mill by-products.
The tour covered the entire process of sugar extraction, highlighting various processes that impact on the quantity and composition of mill mud.
This was the first mill tour for Project CaNE Extension Agronomist Bailey Kilpatrick who appreciated the opportunity to view the milling process from start to finish.
“You can see the effort the Mill is making to extract as much sugar as they can and clean it [from impurities such as mud] as well as they can,’” he shared.
Bailey was interested to see the clarification process with the addition of flocculant and was surprised by the quantity of mud being processed at once through vacuum filtration systems. The automation and chemical inputs such as lime required to keep the juice flowing through evenly also generated interest from the tour group.
Reflecting on the tour, Bailey noted:
“There is actually a lot that goes into getting the mud extracted, it’s not a simple process.“
Following the informative Mill By-product Analysis presentation in July of last year, the Project CaNE team recently held a Mill By-product infield demonstration with Agro Group showcasing the latest technology and methods for applying mill-by products.
Extension Agronomist Graeme Holzberger shared how the workshop was a valuable opportunity for growers to see first-hand how the products are applied.
“To actually see the truck applying it out and have Kristen there to show the process and explain how to manage it…answered a lot of questions.“
Discussions with Project CaNE Extension Agronomists on the day touched on various topics of grower interest, including storing and managing the product once it arrives on farm, application methods such as banding, and the implications for fertiliser rates following different by-product applications.
“One of the growers already uses a product on one of his farms. He was looking at sending mud down to another farm a bit further from the mill. He was concerned about the different environment, different soil type and how that might change the effectiveness of the mud.
Another grower is from the Coolbie Rollingstone district, has never had access to the product but was keen to give it a go. Being there and seeing the process and having those questions answered, he is now considering taking up the practice.“
– Graeme Holzberger, HCPSL Extension Agronomist

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.

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.
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.

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:
The research team from Griffith University and the University of Newcastle are in their early stages of producing organic compounds that can carry imidacloprid for cane grub management.
Recently, the team from The Universities of Newcastle and Tasmania recently visited HCPSL in Ingham, to assess rapid field-based soil tests and a ‘lab-on-chip’ and an app.
Most of the ‘Plant based solutions to improve soil performance’ project team from Southern Cross University, HCPSL, Central West Farming Systems Group (NSW), NSW Department of Primary Industries, Murdoch University, Charles Sturt University, Facey Group (WA), Hart Farming Group (SA) and Riverine Plains Farming Group (Victoria) visited the Hart field trial site at Clare, South Australia and discussed the project findings to date.
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.

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.
In this week’s Back to Basics video, HCPSL Extension Agronomist, Adam Royle covers ‘What is Gypsum?’. Following on from last week’s episode, he explains the difference between gypsum and other ameliorants. Adam also discusses how gypsum works to ameliorate sodic soils.
