Can Australian Agronomy Improve Kansas Wheat?
Getting more wheat from limited water may depend less on finding one breakthrough and more on improving the entire farming system. Australian farming systems agronomist John Kirkegaard Ph.D. joins K-State wheat and forage Extension specialist Romulo Lollato Ph.D. to discuss what Kansas and Australian wheat producers can learn from each other. They explore farmer-led research, water-use efficiency, fallow management, strategic tillage, crop rotations and the new Profitable Wheat Frontier Network being developed to test ideas with Kansas growers under real-world field conditions. Key takeaways: Australian research shows how soil improvement, rotations, fallow weed control and crop management can work together to improve water-use efficiency. Strategic tillage and deep soil amelioration have produced substantial yield responses on certain problematic Australian soils while remaining part of predominantly no-till systems. Better summer fallow management helped Australian growers store roughly 2 additional inches of soil moisture and plant about three weeks earlier. Involving growers and crop consultants from the beginning can accelerate research adoption because producers help identify the problems and test practical solutions. K-State’s Profitable Wheat Frontier Network aims to use on-farm research, precision agriculture and producer knowledge to identify ways Kansas farmers can increase wheat yield and profit. Detailed Timestamped Rundown 00:00–02:09 — Introduction and guests Aaron Harries introduces John Kirkegaard Ph.D., an Australian farming systems agronomist and Fulbright Distinguished Chair visiting K-State, and Romulo Lollato Ph.D., K-State wheat and forage Extension specialist. 02:09–03:52 — Why an Australian wheat scientist came to Kansas Kirkegaard explains the similarities between Australian wheat country and the Great Plains, particularly variable weather and production risk, and describes the international collaboration that brought him to Kansas. 03:52–06:48 — Lollato’s Australian sabbatical Lollato explains his nearly five-month stay in Australia and how the collaboration grew from relationships developed through the international Wheat Initiative. 06:48–12:13 — Australian Wheat 101 Kirkegaard explains Australia’s wheat calendar, hard white spring wheat production, export orientation, rainfall limitations, rotations, large farm sizes, no-till production and the importance of measuring yield relative to rainfall. 12:14–17:32 — Putting growers inside the research process Lollato identifies one of his biggest Australian takeaways: growers and consultants help define research problems and develop solutions from the beginning rather than simply receiving recommendations afterward. 17:32–20:28 — Australia’s Extension alternative Kirkegaard describes the shift from government Extension toward private agricultural consultants. He estimates 70% to 80% of Australian grain farmers now work with an adviser of some kind. 20:28–25:28 — Strategic tillage challenges no-till assumptions The discussion turns to deep soil amelioration. Researchers, engineers and growers developed specialized approaches for restrictive sandy soils. Kirkegaard says yield increases of roughly 30% to 40% can make treatments economically attractive when benefits persist five to six years. 25:28–27:05 — Could similar opportunities exist in Kansas? Lollato discusses Kansas soil constraints and the search for interventions that could improve water capture and crop productivity. 27:05–31:48 — The Australian water-efficiency experiment Kirkegaard describes a major grower-led initiative designed to increase water-use efficiency by 10% in five years. Instead of focusing solely on the wheat plant, participants investigated soil, rotations, fallow and crop management. 30:17–31:48 — Two more inches of stored water Strong summer weed control and residue management helped growers enter the growing season with about 40 millimeters — roughly 2 inches — of additional stored moisture. Planting subsequently shifted about three weeks earlier, and Kirkegaard says the investment in strict summer weed control paid 15-to-1 in that project. 31:48–32:23 — “Incremental transformation” Lollato and Kirkegaard explain how small improvements can compound: conserve water first, adjust planting, select an appropriate cultivar, then adjust fertility to support greater yield potential. 32:23–36:23 — Why farmer-led research gets adopted Kirkegaard describes grower groups, research funding, crop simulation modeling and the importance of farmers testing their own ideas rather than simply receiving recommendations. 36:23–40:47 — Kansas’ Profitable Wheat Frontier Network Lollato introduces plans to work directly with Kansas growers using commercial equipment, soil and leaf samples, yield maps, satellite imagery, drones and other precision-agriculture tools. The goal is greater yield, resource efficiency and profit. 40:47–44:01 — An Australian’s view of Kansas weather Kirkegaard reflects on Kansas humidity and extraordinary temperature variability, along with drought and freeze damage observed during the 2026 crop. 44:01–45:27 — What Australia can learn from Kansas Kirkegaard praises the Wheat Quality Tour and Kansas’ integration of producers, researchers, millers, buyers, food companies and other parts of the wheat value chain. 45:27–46:18 — A season built for studying extremes Lollato notes that Kirkegaard came to study climate extremes and encountered drought, freeze, hail and flooding. Harries recalls Manhattan moving from about 10°F to 98°F in six days. 46:18–47:13 — Closing The guests reflect on continued Kansas-Australia collaboration, and Harries directs listeners to Wheat’s On Your Mind and Kansas Wheat.
