Soil CRC Conference

Posted by Rod Neilson

SOIL CRC conference show cases advancements in soil science and management.

The 2023 Soil CRC conference was held in Launceston, Tasmania between the 29th -31st of August. The conference was a huge success with over 250 delegates attending the event over the 3 days.

The Soil CRC was established in 2017 to give farmers knowledge and tools they need to make decisions on complex soil management issues. It bridges the gap between soil science and farm management, ensuring that soils perform at a high-level, while ensuring profitability and long term sustainability of the soil resource for future generations.

The conference provided some good insights into the projects being worked on, new technologies, good discussions with other grower groups on business structure, operational activities, strategic focus, and issues they experience.

The Soil CRC is a national program, with the only sugar representation coming from HCPSL and Burdekin Productivity Services (BPS). HCPSL / BPS Board member-Ian Davies, HCPSL Company Manager- Lawrence Di Bella, HCPSL Senior Extension Agronomist- Adam Royle and BPS Company Manager- Rob Milla attended the conference.

HCPSL and Burdekin Productivity Services (BPS) have been involved with the Soil CRC since its inception, with 20 other Grower Groups from across the country. Researchers from 13 universities are working across critical issues concerning soils, which have been identified by the Grower Groups as high priorities for their industries.

The first day of the conference consisted of numerous meetings with project teams to review project activities, outcomes, and outputs. One of the notable meetings was with teams from the University of Tasmania (UTAS), University of Newcastle, BPS and HCPSL, coming together to view the progress of the “Lab on a Chip”. This project will develop an affordable field-based tool kit for farmers to quickly determine soil properties soil chemical properties on their farm. The project will develop a user-friendly mobile and desktop interface which will access the measurement data and provide crucial soil nutrient information for the users. During the team meeting the group had the opportunity to trial the newly developed tool to assess soil nitrate, phosphorus, and pH levels.

A meeting was held with Dr Chloe Lai (University of Southern Queensland research scientist) to review the new version of an electronic tool called “Gypsy”. This tool has been developed to assist farmers and advisors develop soil ameliorant strategies for the management of sodic soils. “Gypsy” was developed in the late 1990’s and needed a significant update to include new knowledge gained on sodic soil management, develop capability to interface with EM data and to develop prescription maps for soil amendment applications which is now completed. Going forward HCPSL and BPS agronomy staff will now adopt the program to assist farmers to better manage sodic soils in their respective areas.

The second day of the conference consisted of keynote speakers, researchers and panel discussions on various topics concerning various soil matters. Presentations were of a high quality and the interactions between conference attendees was commendable.

The third day of the conference consisted of three field trips:

Field trip 1- Launceston Environs Soil Health Trials Tour. Adam Royle attended this tour.

The highlights of the tour were the use of GM technologies in the barley breeding program to improve the plants’ ability to better manage waterlogging and crop lodging. The tour also visited Van Dieman’s Brewing which was an integrated business growing most of the materials required to make a great tasting beer. Yes, Adam did get to taste test the end product.

Field trip 2- Midlands soils and Irrigated Landscapes Tour.

Ian Davies attended this tour. The highlights of this tour were the use of AI, sensors and technologies used to manage irrigation systems and their interaction with soils. The tour was hosted by an impressive 2600ha dairy farm operation. The farmer was forward thinking, valued data to make informed decisions, very tech savy using data to advance his business and fully understood the interactions between the pasture, soils, water inputs and milk production. A number of new novel soil measurement tools were also showcased on this field trip.

Field trip 3- Northwest Coast Soil and Landscape Health Tour.

Lawrence Di Bella attended this tour visiting the Tasmanian Institute of Agriculture- Forthside Vegetable Research Facility. At this site the tour group visited the long-term cover crop trial to discuss the soil science behind the use of cover crops obtained from trials conducted across the country. Novel soil conservation methods to better manage soil erosion were observed and smart irrigation systems to better manage irrigation and its interaction with soils were showcased.

The Soil CRC was funded for 10 years and is now at year 6 of its life. Significant learnings have been already made concerning the soil and its management, numerous smart tools are nearing commercial use, data systems to better manage soils are being developed and assessed. The investment into the Soil CRC has and will significantly contribute the advancement of agriculture well past the completion of the program.

Update on Rats

Posted by Rod Neilson

HCPSL recently invited staff from Animal Control Technologies Australia (ACTA) to view firsthand the impact of rats on the current cane crop and the effectiveness of RATTOFF®.

ACTA and HCPSL staff inspected fields across the district on Wednesday the 9th of August, where RATTOFF® had recently been applied, to view the efficacy of the product and its impact on rat populations. Upon inspection of treated blocks, sachets were found to be opened by rats and there was a significant decline in rat damage of the treated blocks.

Photo above. A RATTOFF® sachet which has been opened by a rat found in a field treated in the Abergowie area.

RATTOFF® contains zinc phosphide coated grain which is quite stable while kept dry in the original packaging. Once eaten by the rat, the chemical quickly reacts with its stomach acids to produce poisonous phoshine gas in the gut area.

Research trials indicate that around 3-5 treated wheat granules were sufficient to kill a rat, hence one RATTOFF® sachet has the potential to kill about 50 rats. It is also not uncommon to find unopened sachets in a treated field due to of the sheer number of sachets applied and the effectiveness of the bait to control rats.

Rats will commonly drag the sachets back to their nests. Not only does this remove the sachets from above the ground but it also delivers the product directly to the colony.

The RATTOFF® sachet consists of a cellulose membrane that is water resistant and will break down over time due to UV light (usually occurring after 28 days). The sachet protects the treated wheat grains and provides a protective covering in the event of rain.

Research conducted tested the effect of additional palliative attractants to improve RATTOFF® uptake by rats. The trial results were non conclusive but found in some cases that the addition of linseed oil did improve uptake. ACTA and HCPSL staff also inspected young ratoon crops and found significant rat activity in these blocks. Growers are urged to start controlling rats in these crops to avoid carry over to next year’s crops.

When treating a field, two applications of RATTOFF® may be required. The first application will target those rats above ground, not the lactating mothers and their young that are in borrows. A second application is required approximately 6-8 weeks later when these lactating mothers and the new juveniles come to the surface to feed. Growers should monitor the blocks to see if further applications are required.

RATTOFF® is registered for use in sugarcane crops through both ground and aerial applications by drone or helicopter. The recommended application rate of the product is 100 sachets per hectare or a total of 1kg of bait material per hectare. Racumin is the only other registered bait for use in sugarcane with baits needing to be placed in a bait station. The recommended rate for this product is 60-100g per bait station.

Other anticoagulant baits are not registered for use in sugarcane because they pose a risk to wildlife and persist for long periods in most animals.

An Integrated Pest Management (IPM) program should be considered to reduce rat numbers. Rat baiting is only one tool in a farmer’s toolbox when other measures are not effective in managing rat population numbers. As a part of an IPM program consider the following: managing weeds in crop, drainage lines and riparian areas by mowing, spraying and revegetation of habitat areas.

HCPSL on show to the Herbert Grower Representatives

Posted by Rod Neilson

On Tuesday the 25th of July, HCPSL was on show with Herbert grower representatives attending a bus trip to HCPSL sites. Representatives from ACFA, AgForce, Herbert River CANEGROWERS and HCQR, as well as HCPSL Board members and staff, got to view firsthand the on-ground services and extension activities that HCPSL delivers to the Herbert cane industry.

Grower representatives had presentations or viewed firsthand the following:

Rhiannan Harragon (HCPSL Field Agronomist) also presented data on the number of growers who requested RSD testing of seed cane for planting and the level of RSD infection. To date it was revealed that 69% of growers had not tested their seed cane prior to planting and that 9% of the samples tested were infected with RSD. The grower representatives all agreed it is very concerning growers were not testing their seed cane sources before planting and that there was a high level of RSD infection in growers seed cane. Growers are urged to purchase Approved Seed cane from HCPSL to curb the infection of RSD in commercial cane crops and to take advantage of the free seed cane inspection service HCPSL provides.

The day was very successful with Grower representatives leaving satisfied with the services being provided by HCPSL to their members.
