Humans of Agriculture

The Tom & Mick show continues with a practical conversation on livestock trading, grazing systems, business resilience and long-term decision making.

Tom and Mick are joined by Nigel Kerin, CEO of Kerin Ag, to unpack how his business approaches livestock trading, forward contracts, pasture management, Wagyu, and the systems that drive profitability through both dry and strong seasons.

From the role of grass budgets and forward pricing to lessons from drought, inflation and on-farm technology, Nigel shares a grounded look at what it takes to build a resilient livestock business.

In this episode:
Nigel’s background and Kerin Ag
Central west NSW grazing business based south of Dubbo
Kerin Ag founded through succession in 2007
Built around Merinos, a newer Wagyu seedstock arm, and a growing trading enterprise
How the trading business works
Trading introduced as a pressure valve for seasonal variability and cashflow
Decisions driven by grass budgets, not headline market prices
Focus on securing the sell price first, then finding the buy
Forward contracts used to remove emotion and manage downside risk
Why relationships matter
The value of strong relationships with agents, commission buyers, financiers, processors and transporters
Creating win-win outcomes across the supply chain
Why trust and consistency matter when operating at speed in trading markets
The 2020 lamb trade
Locking in a $9/kg dressed weight JBS contract as drought broke
Contracting 15,800 lambs before owning any of them
How forward pricing protected the business when the spot market later fell sharply
A defining trade that helped get the business back in the black
Should every livestock producer trade?
Nigel’s view: absolutely not
Why trading needs systems, rules, finance and discipline
The danger of trading without forward pricing or without enough grass
Technology and grazing systems
Regular pasture analysis every 10–14 days in growing periods
Using OptiWeigh, soil moisture probes and grazing data to drive decisions
The emergence of a new grazing app Nigel describes as potentially “the auto-steer for grazing”
Why Kerin Ag moved into Wagyu
Return on grass as a major driver
Lower adult cow weight and efficiency compared with larger framed alternatives
Taking a long-game view on Wagyu economics rather than reacting to short-term cycles
Inflation and on-farm economics
Nigel’s estimate that on-farm inflation has run at 7.8% annually post-COVID
Why understanding business cost inflation is critical to decision making
The importance of introducing structural change in good times, not when under pressure
Key business lessons
Systems matter more than goals on their own
Feed efficiency and speed of turnover are central to profit
In agriculture, long-term averages matter more than short-term noise
“Don’t run out of grass” remains one of the core rules of a successful trading business

This episode is full of practical insight for livestock producers, graziers, advisors, seedstock operators and ag businesses thinking about risk, trading, pasture utilisation and long-term business performance. It’s a valuable conversation on how to build guardrails, use data well, and make better decisions through changing seasons and volatile conditions.

Charlie Blomfield isn’t just building a farm business, he’s building a voice that agriculture can’t afford to ignore.

In this episode of Humans of Agriculture, Oli sits down with Charlie Blomfield at Boridgeree, just outside Canowindra in Central West NSW. Farmer, business owner, marketer and one of the most talked-about voices in Australian agriculture right now, Charlie shares what’s driving him, how he’s built GreatHAY, and why he’s chosen to step so publicly into conversations around ag, media and advocacy.

From growing up in a tough era for agriculture, to working across Northern Australia and the Middle East, to building a modern mixed farming and hay business from the ground up, Charlie’s story is shaped by curiosity, conviction and a willingness to back himself.

But this conversation goes beyond the farm gate.

It explores the role agriculture must play in telling its story better, why traditional industry communication is falling behind, and how humour, clarity and honesty are helping Charlie connect with audiences far beyond agriculture.

This episode is about leadership, relevance, building teams, making hard decisions under pressure, and why the future of agriculture depends on more people being willing to speak in ways the rest of the country can actually understand.

Key insights from the conversation
How Charlie went from asset management and private equity to building Boridgeree
Why water security and flexibility shaped their move to Canowindra
The evolution of Boridgeree from mixed farming into a branded hay business
Why GreatHAY was built around simplicity, clarity and cut-through

What if agriculture’s biggest opportunity isn’t on farm, but in the classroom?

In this episode of Humans of Agriculture, Oli sits down with Scott Graham, Head of Agriculture at Barker College in Sydney. From a a student base that’s almost entirely from the city, Scott has built the largest Year 12 agriculture cohort in Australia, completely reshaping how young people see the industry.

Scott isn't focused on just one school, he is also completing a PhD focused on engaging metropolitan students in agriculture, and what he’s learned challenges how the entire industry thinks about talent, careers and perception.

This conversation dives into what’s holding agriculture back from attracting the next generation and what needs to change if we’re serious about building the workforce of the future.

Key insights from the conversation
Why agriculture needs to move beyond farming stereotypes to attract urban talent
How Barker turned agriculture into one of the most in-demand courses in the school

In this episode of Humans of Agriculture, we sit down with Jack Ternouth, Head of Commercial Operations at Zentera (formerly New Zealand Merino Company), for a conversation that captures what’s possible when curiosity, grit, and opportunity collide in agriculture.

Jack didn’t grow up on a farm, but through sheer determination and a willingness to learn, he’s built a career from the ground up in one of the most complex and globally connected parts of the ag industry. From classing wool and working alongside growers to now leading commercial conversations with global brands, his journey is a powerful example of what’s possible in ag today.

On this episode, we explore what it takes to build a career in agriculture without a traditional background, the critical role of mentorship, and why value creation - not scale - is the future for countries like Australia and New Zealand. Jack also shares how Zentera is helping create more certainty for growers in a volatile market through traceability, long-term contracts, and global brand partnerships.

This episode is about ambition, learning on the go, and the next generation shaping agriculture’s future.
