1. Can Soil Information Better Inform Canopy Sensor Algorithms for Corn?Corn production is often limited by the loss of nitrogen (N) due to leaching, volatilization and denitrification. The use of canopy sensors for making in-season N fertilizer applications has been proven effective in matching plant N requirements with periods of rapid N uptake (V7-V11), reducing the amount of N lost to these processes. However, N recommendation algorithms used in conjunction with canopy sensor measurements have not proven accurate in many fields of the U.S. Cornbelt, resulting in... , N.R. Kitchen, J.

2. Tillage, Cereal Rye Cover Crop, and N Placement Effects on Corn and SoybeanAlthough conservation tillage and cover crops can improve soil health, producers are hesitant to adopt these practices due to concerns about potential yield reductions. We conducted field experiments for four years (2020-2023) near Urbana, Illinois, to explore how these practices affected corn and soybean yields. The experiment was conducted on a Flanagan silt loam soil, with corn and soybean following one another on two sides of the same field. Treatments were arranged in a RCBD with four replications.... F.
