In the south and west, many growers are facing dry conditions and tightening fertiliser budgets.
Further north and through central regions, flooding has brought nutrient loss, soil structure damage and the challenge of rebuilding paddocks.
According to Biolink 4 Plants & Animals co-owner Kevin Beecroft, the response in both situations starts below ground.
“Whether it’s drought or flood, the common factor is soil stress,” Kevin said.
“When conditions are extreme, soil biology is usually disrupted.
“Rebuilding that biology is one of the smartest investments growers can make.”
Kevin believes autumn fertilising should focus less on chasing top growth and more on improving fertiliser efficiency and root development.
“Growers don’t want to spend more than they have to,” he said.
“What we concentrate on is helping farmers get more out of the fertiliser they’re already using.
“If soil microbes are active, nutrients are less likely to be lost and more likely to be available when plants need them.”
In dry regions, biologically active soils can improve nutrient retention and strengthen root systems, helping crops and pastures respond quickly when rain arrives.
In flood-affected areas, restoring microbial balance supports nutrient cycling and helps rebuild soil structure.
Autumn is also an ideal time to deal with residues and organic waste.
“Instead of burning stubble or letting residues sit idle, we encourage growers to turn that material into an asset,” Kevin said.
“Building soil carbon improves moisture-holding capacity and long-term productivity.”
As seasons become more unpredictable and input costs remain high, Kevin believes resilience is the real goal.
“What you do in autumn sets up your whole growing year,” he said.
“If you strengthen the soil now, you’re giving yourself the best chance of handling whatever conditions come next.”
