1. Some Effects of Soil Compaction on Root GrowthRoot growth and nutrient uptake are obviously related, and yet not well unders tood under field conditions . An oversimplified premise is that plant roots must grow to the site in the soil where the nutrients are retained, or that the nutrient must move to the absorbing root sur-face (or both). Relationships developed under well controlled uniform laboratory conditions of ten do not extrapolate to field conditions. In this respect, progress is often hindered by the fact that root growth measurements... |
2. Elucidating How N Management Practices and Excess Water Conditions Affect Corn N Uptake and Grain YieldFlooding and waterlogging events have been more frequent in the Midwest region, causing corn yield penalty nitrogen losses through leaching and denitrification processes. Improving N fertilizer recommendations for areas prone to flood conditions is necessary to minimize N losses and optimize corn yield. This research aimed to determine how N application practices before and after waterlogging events impact corn growth and grain yield. A field experiment was initiated in 2021 in Custar, Ohio using...

3. Nitrogen Application Timings in No-Till Dryland Corn Production SystemRight timing of nitrogen application is one of the practices of the 4 R nutrient stewardship. Three independent trials using a randomized complete block with 4 replications were conducted to determine the optimal (1) split rate, (2) proportion and (3) timing for sidedress N application in non-irrigated corn. In trial 1 (13-site years), five N rates were examined: 60, 120, 180, 240, and 300 lb N/A, which were applied at two split-applications. Split-applications included single- and split-application....
