1. Environmental Sulfur Sources as Inputs for Predicting Sulfur NeedsCrop responses to sulfur fertilization have been damstrated in mt states in the midwest, but the frequency of these responses is relatively lm. Sulfur deficiencies are usually confined to areas where one or mre of the follcrwing conditions exist: (1) Sandy or shallow soils; (2) Low soil organic matter content; (3) No recent manure applications; (4) Low atmospheric sulfur deposition; (5) High crop sulfur requirement. Although diagnostic tests to predict crop response to applied sulfur are an cbvious... |
2. Exploring the Impact of Temporal Variability in Emergence on Corn Grain Yield and Development PatternsConcerns have raised among farmers in the Midwest regarding the impacts of uneven emergence of corn (Zea mays L.) seedlings. Research has showed that even a minor delay in emergence of a few hours could have a substantial influence on plant performance and ear weight; and one of the contributing factors to uneven seedling emergence in corn is the application of starter fertilizer. Placing fertilizers in the seed furrow increases the salt concentration surrounding the seed and as a result, delays... L. Dorissant, P. Kovács, J. Clark |
