摘要: The objective of this study is to determine the potential for using spatial econometric analysis combine yield monitor data estimate site-specific crop response functions. specific case nitrogen (N) application corn production in Argentina. Spatial structure modeled with landscape variables, spatially autoregressive error and groupwise heteroskedasticity. Results suggest that N differs by position, may be modestly profitable. Profitability depends on model specification used, all models consistently indicating profitability, whereas nonspatial do not.
