Changing storage practices may lead to an improved falling number

New research supported by GRDC and led by Agriculture Victoria scientists Dr Cassandra Walker and Dr Pankaj Maharjan suggests that on-farm storage practices may play a role in lifting the falling number of wheat after harvest. Their work showed that wheat samples with a moderate falling number (200–300 seconds) could increase by up to 50 seconds during 24 weeks of storage, often moving them above the key 300-second benchmark. High-range samples above 400 seconds continued to improve until plateauing at around 36 weeks, while low-range samples showed little change.

The latest Kondinin Group sealable storage report is here! Building on the 2022 review of grain silos, this updated report provides fresh insights, performance comparisons, and practical guidance for growers considering on-farm storage options.

The new findings highlight key changes in silo performance, sealing effectiveness, and best-practice recommendations to help growers make informed decisions when investing in grain storage infrastructure.

Seeds need cool, dry conditions, no matter the variety

As investment in on-farm storage grows, new research shows why it is critical to maintain wheat seed in cool, dry conditions

Agriculture Victoria research scientist Dr Cassandra Walker was not surprised that her study into the impact of storage conditions found that wheat seed viability declined at higher temperatures.

But what did strike her was the significant role that moisture plays, and in particular the difference in viability between grain moisture levels of 11 and 14 per cent.

“We studied two moisture levels – the upper end of what is considered safe at 11 and 14 per cent – and clearly there’s a tipping point between them where grain viability is lost,” she says. “So moisture content has a big part to play, as well as temperature, in germination potential. You can preserve grain viability for longer with lower moisture levels.”

Maximizing Grain Storage Protection with Diatomaceous Earth (DE)

Diatomaceous earth (DE) is a proven solution for pest control in grain storage, but its effectiveness depends on uniform application. Recent research highlights that battery-powered and petrol-powered blowers with venturi attachments deliver superior distribution compared to traditional compressed-air methods.

New research shows wheat falling number may improve after storage

GRDC Grain Storage Extension Team lead Chris Warrick said trials by Agriculture Victoria’s research team at Horsham SmartFarm indicated wheat falling number could increase by up to 50 seconds and even exceed 300 seconds post storage.
where wheat had an initial falling number of less than 250 seconds, no change in falling number was observed.
Mr Warrick said while the research was preliminary it had yet to be replicated in farm storage conditions.

Insect Control and Effective Fumigation Help Guard Your Harvest

Protecting your harvest from insect threats requires diligent control and precise fumigation practices. In GRDC’s article, Insect Control and Effective Fumigation Help Guard Your Harvest, the focus is on strategies to enhance biosecurity and preserve grain quality. Key points include:

Fumigation Best Practices: Effective fumigation techniques are critical for eliminating pests while safeguarding the crop.
Biosecurity Measures: A strong biosecurity approach helps prevent insect infestations before they become a threat.
Integrated Pest Management: Using a combination of methods, including proper storage and sanitation, can minimize pest risks.
