Figure showing the marginal net returns to N fertilizer application for irrigated corn following corn and corn following soybean. The analysis was done for $4/bu corn and fertilizer costs of 7 lb N and 9 lb N equal to value of one bushel of grain or of $0.57/lb N and $0.44/lb N, respectively.

Effects on Profitability and Nitrogen Loss from Reducing N Rate for Corn

February 5, 2019
This study looks at how various reductions in nitrogen application rates in corn might reduce nitrogen loss to the environment and what the costs of those changes would be in yield and profit.

Corn Disease Update

January 9, 2019

The 2018 crop season got off to a slow start with cold, wet conditions delaying planting in much of the state. Some seedling diseases developed in early planted corn, but with ample heat units the corn caught up quickly and most of the crop finished ahead of schedule. High relative humidity and rainfall drove the development of several leaf diseases mid-season.

Critical Time for Weed Removal in Corn and Soybean is Delayed by PRE-Herbicides

January 9, 2019
Understanding the critical time for weed removal in corn and soybean would not only ensure effective weed removal and minimize unnecessary weed control inputs, but could potentially help minimize the development of herbicide resistance in weeds.
