Maize Nitrogen Response as Affected by Soil Type and Drainage Variability

Site-specific application of nitrogen (N) to maize (Zea mays L.) may provide economic and environmental benefits. Variations in soil drainage and texture within fields are often believed to cause localized differences in soil N availability and therefore are a potential basis for site-specific N fertilizer application. The objective of this study was to evaluate the effect of imposed variations in drainage conditions in two soils on early season...
