Planting timing studies have become one of my favorites because of the interactions with organic matter mineralization and season long weather differences . But I think the farm crew isn't fond of the sidedress and spray schedules for 10 foot wide passes.....

🌊 A new study in CFTM shows that routine Mehlich-3 soil tests and rapid EC measurements can accurately estimate standard salinity ratings. The findings could help improve management of salt-affected soils across the Mid-Atlantic. Read more: doi.org/10.1002/cft2.70121
