Planting depth and within‐field soil variability impacts on corn stand establishment and yield

Abstract Seedbed conditions during corn (Zea mays L.) planting can have substantial impact on corn stand establishment and final yield. Planting management decisions are complex due to spatial variability caused by changing soil characteristics such as soil texture or landscape position. Field exper...
