More than 4,000 acres on Justin Regehr’s family no-till farm in Kansas are managed by just three people: Justin, his brother and their father. They have practiced no-till for 15 years, grow cover crops and produce their own biological starter.
In Oklahoma, winter wheat is often grown for two purposes: cattle grazing and grain production. Brian Arnall explains when farmers stop grazing and what determines the final decision.
At an Oklahoma research plot, corn was planted 2 to 4 inches deep. What did deeper planting change, and why are local recommendations shifting?
Can no-till require tillage after 15 years? A continuous wheat experiment leaves more questions than answers.
Winter wheat has been grown continuously in the Magruder Plots since 1892. The long-term comparison of unfertilized, manure, NPK and limed treatments reveals how 134 years of management changed yields, soil organic matter, pH and microbial communities.
A $400,000 combine harvests only about 0.4 hectares per hour. At Oklahoma State University, Dr. Brian Arnall explained why speed is not the priority for a plot combine and what data it collects from each research plot.
Ukrainian farmers already use no-till, cover crops, and other regenerative practices, yet systematic domestic research remains scarce. Why is agricultural science responding so slowly to changes already taking place on farms?
The same hybrid, planting date, and nitrogen rate, yet completely different yields. During a visit to Veris in Kansas, I saw how mobile soil sensors reveal what lies beneath the field’s surface and help explain differences that ordinary soil sampling may miss.
On Michael Thompson’s farm, the farming system is inseparable from economics. Weather, available moisture, and field conditions determine what makes sense in a given year, while machinery must, above all, do its job reliably.
Do cover crops use up moisture in dry conditions? Michael Thompson’s experience in Kansas shows how species selection, termination timing, crop residue, and soil condition determine whether cover crops compete for water or help the soil absorb and retain it.
