Wet soils, soybean surprises, and switching corn maturities | Wheat Pete's Word, May 20

Cold soils and uneven planting progress raise agronomy concerns across North America. Early planted soybeans can remain resilient even after cold-water imbibition and delayed emergence. Wet soils can cause major yield loss when high-speed discs and vertical tillage are used. Planting progress varies widely in Ontario, while frost, drought, wind, and snow damage western crops. Later-seeded cereals need higher seeding rates despite slightly higher lodging potential. Corn growers in shorter heat unit regions should consider shorter-season hybrids. Resistant Canada fleabane continues to challenge IP soybean systems. Smooth rolling soybeans is safe before emergence or after unifoliate stages, but not at hook stage. Broadcast phosphorus on corn performs worse than banded placement. Fall-applied potash outperforms spring applications in soybeans. Strobilurin fungicides at wheat heading can increase DON risk under Fusarium pressure, while competitive fungi on wheat heads can suppress Fusarium in humid regions.

"Later-seeded cereals require higher seeding rates, despite slightly higher lodging potential Corn growers in shorter heat unit regions should now consider switching to shorter-season hybrids Resistant Canada fleabane remains a major challenge for IP soybean production systems"

"Smooth rolling soybeans is safe before emergence or after unifoliate stages - not at hook stage Broadcast phosphorus applications on corn remain disappointing compared to banded placement Fall-applied potash continues outperforming spring applications in soybeans in recent research. Check out new University of Minnesota research"

"Strobilurin fungicides at wheat heading increase DON risk where Fusarium pressure exists Competitive fungi on wheat heads help suppress Fusarium infections in humid growing regions"
