Rain at harvest can leave the seed you keep shot and sprung. Shot grain has a root or shoot showing and will not grow as seed. Sprung grain has swollen and split the skin over the germ. It can still be viable, but its vigour is often markedly reduced.

If you are keeping seed this harvest:
• test it as it goes into the silo, again one to two months into storage, and at least two months before planting
• make vigour part of the test, because weather-damaged seed can pass a germination test and still establish poorly in the paddock
• both germination and vigour should be at least 80%
• store cereal seed at 12% moisture or less and 20°C or less
• do not keep seed from a crop that had glyphosate applied before harvest

We can help you decide which paddocks and loads to keep, take the samples, send them to an accredited seed testing lab for germination and vigour, and build the results into your planting rates for 2027.

Spreading tebuthiuron this season? Two things to get right before you order.

The rate. It comes down to your soil and what you are trying to kill. Heavier clays need more, lighter soils less, and for brigalow regrowth the top of the label range is double the bottom. Too light and you pay for a partial kill. And do not count on it for false sandalwood: the labels only claim partial control and suppression.

The law. In Queensland, poisoning a native tree is clearing, and the state clearing codes name tebuthiuron and restrict where and how it can go out. Since December 2025, the federal "continuation of use" exemption no longer covers vegetation that has not been cleared in the last 15 years. That is not a ban, but it does mean more jobs need checking first. NSW has its own rules, and the federal test applies there too.

We have put the detail in one place: https://www.dawsonag.co/agronomy/tebuthiuron-rates-clearing-laws/

If you want to work through the right rate for your country, or what your property report and the federal changes mean for you, call our agronomist Jeremy Dawson on 0484 058 231. We are independent, so our advice is not tied to any product or supplier.

A dry finish brings crown rot out, and we are seeing plenty of it in paddocks this season.

Whiteheads are a poor guide to how much you have. They say more about how tough the finish was. What matters for 2027 is how much fungus is sitting in your stubble: it survives there for three years or more, and dry conditions slow the breakdown.

The time to check is while the stubble is still standing, up to about a month after harvest:
• pull five plants at each of 10 spots across the paddock
• peel back the leaf sheaths and look for honey to dark brown discolouration at the base of the stem
• under 10% of plants affected is low risk for the next cereal crop, 11 to 24% is medium, over 25% is high

What you find should shape next year: which paddocks go back to cereal, how long a break you need, variety choice, inter-row planting and how hard you push nitrogen.

After harvest, we can also take stubble samples and send them to a government lab that tests them for crown rot free of charge. You only pay for our time in the paddock and the freight.

Jeremy's home, the bags are unpacked, and the notebook is full.

The last farming stop of the Spraytec Ag Tour was the Farm Progress Show in Iowa, billed as America's largest outdoor farm show. Machinery in every direction, a grower panel at the Spraytec booth to start the day, and iron you don't see every day, including a Case IH Steiger 715 Quadtrac wearing the stars and stripes.

A week of walking crops, farms, research labs and showgrounds with growers and agronomists working different soils but asking the same questions we ask at home.

Now the real work starts: sorting which ideas actually earn a place in our paddocks in Queensland and New South Wales.

While Jeremy's been walking corn in Iowa, Keeley was flying the Dawson Ag flag in Sydney

She spent two days at the 2026 Australian Precision Agriculture Symposium at the University of Sydney, hosted by SPAA, the Society of Precision Agriculture Australia. Yield maps, management zones, and a room full of people working out how to make precision ag actually pay on farm.

Dawson Ag is one of the consultants in the national SPAA and GRDC project on variable rate fertiliser, working with southern Queensland growers across the 2026 and 2027 seasons, so there was plenty to compare notes on.

Keeley's take: "A great opportunity to meet other industry members passionate about precision ag, and to hear grower feedback on their current operations and where they see PA going on their farms."

Two agronomists, two continents, one job: better decisions for our growers' paddocks.

“Farming is Everyone’s Bread and Butter.”

That’s the sign over the door at The Machine Shed, the Iowa restaurant that calls itself a tribute to the American farmer. Over here, farming isn’t tucked away in the regions. It’s on the main street, in the stadium, and all through the university.

A big day on the Spraytec Ag Tour for Jeremy, research presentations at Iowa State University, time with a record-setting corn grower, a walk through the Alliant Energy Agriculture Innovation Lab at the ISU Research Park, a farm visit at Bush Family Farms in Boone, and corn at full height everywhere in between.

Plenty of ideas worth weighing up for our own paddocks. Farm Progress Show tomorrow, he’s been counting down for this one!

Real Iowa farming country.

Jeremy's in the US Midwest this week walking corn and soybean country on some of the deepest cropping soil in the world. Crops for miles in every direction, and plenty of good people talking farming.

Different country, same job: working out what makes soil perform, and bringing the useful ideas home to our paddocks.

He also squeezed in a stopover catch-up in LA with his mate, actor Angus Sampson.

More from the road later in the week.

Paraquat wasn't banned. But if you run a boom, the rules just changed in a way that matters.
The APVMA review has cut the maximum rate for conventional boom spraying to about 1 L/ha of a 250 g/L product. For context, we've rarely recommended less than 1.8 L/ha for reliable control of broadacre fallow weeds.
What that means on the ground:
Small, actively growing weeds should still be controllable
• Large fleabane, feathertop Rhodes, sowthistle, button grass and moisture-stressed weeds get much harder with paraquat alone
• Conventional boom spraying loses a lot of its punch at ~1 L/ha
The good news is optical spot spraying. The new labels keep a higher rate for spot sprayers, because only a fraction of the paddock is treated (sprayed area must stay under 30%). If you're running WEED-IT, Bilberry, John Deere See & Spray or WeedSeeker, you're in a much better spot.
A couple of things to know: there's a two-year transition, so what's in your shed on the old label is still usable. And the new labels bring enclosed mixing and loading, the end of backpack sprayers, and more PPE.
If you want to work through what this means for your fallow program before planting, give us a call.

TRUCK DRIVER / MACHINERY OPERATOR WANTED - Goondiwindi, Tara or Meandarra

We're an independent family agronomy and soil testing business working farms from Dalby out to St George and down to the border, and we need an operator. Casual with an immediate start, building to full time as the soil testing side continues to grow.

The work: our Kelly Chains and Grizzly go out on dry hire, so you're the one picking them up from the last job, going over them, fixing what needs fixing and carting them to the next farm (MR licence needed). You'll also do soil sampling and drive the EM survey gear - we train all of that, you don't need to know anything about soil yet.

We're after someone handy on the tools, good around machinery, and extremely reliable and teachable.

You'll be away some nights. Travel, accommodation and meals are covered, and there's a work ute. We have a great team, plus, it's good money!

You'd want to be living around Goondiwindi, Tara or Meandarra already - no relocation.

Jeremy’s spent the week running pasture visits across western Queensland. Longreach, Winton, Cloncurry and everywhere in between.

Pasture condition, species mix, soil testing on the spot. Plenty of windscreen time, plenty of good country, magic sunsets and getting to have a b**r at the Burke and Will Campdraft with Harry Dawson made the drive worth it.

Always good to get out west.

📞 0484 058 231 if you’d like Jeremy to swing by next trip.
