ABSTRACT Irrigated corn producers on the High Plains are frequently confronted with issues that affect the profitability of their operations. The rapid adoption of new methods and technologies that preserve profitability is important for the economic sustainability of High Plains farmers. Traditional research is one method of identifying best management practices that may improve grower productivity and profitability. However, dissemination and implementation of research across broad geographies can be challenging. The scientific method often precludes investigation across a diverse set of variables common within and across farms. Private industry can augment implementation of scientific methods identified as profitable best management practices by employing resources necessary for wide scale spatial and temporal demonstrations. Furthermore, these investigations can be instrumental in prompt identification of processes and practices that improve producer efficiencies and/or profitability. The work and investigations summarized in this paper will demonstrate the use of spatial and temporal observations to identify best management practices for multiple nitrogen (N) applications through corn development. Also, the extension of university research on P and K starter fertilizer and its adoption and implementation by growers will be discussed
