After three consecutive wet years and multiple high production seasons in the north, experts are warning growers that the old rules of thumb for calculating nitrogen (N) rates won’t cut it this season.

A public environmental review has been set for a mineral sands project proposed for about 21km east of Ledge Point and 800m south of the Moore River due to the extent of further information required, the number of preliminary key environmental factors identified and the moderate level of public interest in the project. When the Environmental Protection Authority (EPA) published its decision to assess the Bidaminna project proposal it said out of the 156 submissions received 153 had called for public environmental review.

Kristin Murdock. With the school year approaching an end, students have been busy finishing off projects ... Shearing and marketing of the lambs has also occurred recently, with Agricultural Studies students from all year levels taking part in the process.

South Australian grain growers and agronomists are set to gain advance access to the latest research findings, meet experts and network at SA’s premier grains research forum next month. The 2023 GRDC Grains Research Update – Adelaide will be held on February 7 and 8, with more than 400 people expected to attend. Keynote presentations will also be livestreamed.

In a cruel blow to Australian farmers, the Federal Labor Government has confirmed it has axed the $54 million pilot Soil Monitoring Incentives Program (SMIP) because of flooding ... "Labor’s decision to end the SMIP is disgraceful and it reflects their contempt for our farmers and the $85 billion agriculture industry": Leader of The Nationals and Shadow Minister for Agriculture, David Littleproud.

Greenmount-based business Kialla Pure Foods has been awarded the Brand of the Year award at the 2022 Australian Organic Industry Awards ... Kialla’s flour mill is one of the last remaining in Australia which operates in the farmland where the grains are grown. “We’re proudly based in the heart of the Darling Downs, surrounded by the rich black alluvial soils that run through this region”: Quentin Kennedy.

With the price of Australian fertiliser imports rising by a record 128 per cent, PyroAg, a leader in creating commercial quantities of Pyroligneous acid or wood vinegar, is urging Australian farmers to embrace the next generation of sustainable farming practices, as well as stripping their fertiliser costs significantly, with scientifically backed high density liquid that will provide proven substantial benefits to the Australian agricultural sector.

Chris Oldfield. The Liberal Shadow Cabinet will continue to support a moratorium on fracking in the SE which runs until 2028. It will also continue to work on land access through agricultural properties to mines because “both agriculture and mining are important to the economy”.

This year the theme of World Soil Day is ‘Soil: Where food begins’, highlighting the importance of healthy soil as a crucial element of food production ... “Soil in good condition is more productive. It has higher water-holding capacity, supports biological activities and resists erosion during extreme climate and weather events": Lisa Nitschke, DAFF.

Matthew Harrison's presentation covers a range of issues relating to soil carbon markets, from changes in soil carbon over time to whether we should rethink soil carbon markets, beginning with the key question: why all the hype about soil carbon?

A team led by University of South Australia researchers has pioneered a new soil remediation technique that is significantly faster, simpler, safer, and more cost-effective than currently available method … a new remediation technique that uses a super-efficient solar evaporation surface to draw water from the soil through a sponge-like filter that traps contaminants, mimicking the process of transpiration that occurs in natural plants, but at a greatly accelerated rate.

With wet conditions saturating large areas of crop production land across Victoria and Tasmania, a GRDC project is identifying ways to maximise crop performance when waterlogging occurs ... Applying nitrogen can help crops recover after being waterlogged, and looking at where waterlogging occurs when it is happening can help growers to plan improved drainage to prevent future waterlogging.

A good place to start reading Farm is at the back. That may sound counterintuitive but by taking a look at the extensive bibliography you’ll quickly see how intensely researched the book is which adds weight to the arguments and questions it presents. While Farm is a memoir that chronicles the journey of Nicola Harvey and her husband after they leave their city lives to farm cattle in rural New Zealand, it is far more than that.

Kylie Cook. Natural Intelligence Farming improves pasture diversity and productivity, rebuilds soils, repairs landscapes and benefits human and livestock health. The manager of Prospect Pastoral Co, a Wheatbelt mixed cropping and livestock operation of more than 60,000ha, Di Haggerty, spoke to the Wilson Inlet Growers Group in July ... She said Wheatbelt farmers faced many challenges, a drying climate, ‘gutless’ sandy soils, salinity and erosion of bare ground between cropping seasons.

Public consultation is now open on Australia’s first national action plan on soil ... “As the first action plan under the 20-year National Soil Strategy, it is important that there is a focus on setting good foundations for future actions to halt and reverse soil degradation and improve soil health”: DAFF

Chris Oldfield. A Koppamurra Landholder Reference Group (KLRG) has been formed by Australian Rare Earths as it takes another step towards developing a mining lease application ... The aim of the landholder reference group is to share information and seek feedback on the Koppamurra project.

Sustainable land management in Western Australia has been boosted by a ground-breaking initiative that has more accurately calculated the extent of salinity in the agricultural region to support new approaches to conserving natural assets and agricultural productivity. The 'Mapping salt-affected land in the South-West of Western Australia using satellite remote sensing' report by the national science agency, CSIRO, and the Department of Primary Industries and Regional Development (DPIRD) was released at a forum in Perth.

Mount Alexander Sustainability Group’s Healthy Soils team is looking for commercial farmers with soil issues within a 50-60km radius from Castlemaine. This Healthy Soils Project offers the opportunity for 20 participating farms to receive free soil constraint assessments and soil testing, as well as assistance with developing a soil health management and monitoring plan.

Australian owned agricultural technology company Agrimix is set to release a toolkit that will see the cost of soil carbon measurement cut up to 90%.

A 12 month trial on a cotton farm just outside the rural town of Goondiwindi Queensland in Australia has shown it’s possible to divert large amounts of cotton textile waste at end of life from landfill with no harm done to soil health or cotton yields. Project collaborators are confident that with a solid business plan and more research, returning shredded cotton products to cotton fields could soon offer benefits to soil health, and a scalable solution to the massive global problem of textile waste.

“Comparing soil health in sugarcane growing districts to soil health in pasture, horticulture and cropping regions shows just how unique those sugarcane soil systems are. Many cane growers may not have measured their soil health before but with commodity prices remaining strong in this regulated market, we’re seeing cane growers becoming increasingly interested in soil health" : Rob Dwyer, Incitec Pivot Fertilisers agronomist.
