7 The Fluid Journal Winter 2015 Starter Fertilizer @ V6 Right Fertility Components Critical In High-Yield Corn Study includes fertilizers used and application methods. The Fluid Journal • Official Journal of the Fluid Fertilizer Foundation • Winter 2015 • Vol. 23, No. 1, Issue #87 Corn is grown on an estimated 600,000 irrigated acres in the Texas and Oklahoma Panhandles, northern New Mexico, and southwest Colorado. Corn production in these areas involves intense management and numerous inputs to achieve yield goals. Over the past 20 years, producers in these areas have faced fluctuating markets, increased input costs, environmental shifts including extreme heat, exceptional drought, declining groundwater and surface water, and state-mandated pumping restrictions. These changes have driven corn producers to improve operational efficiencies to maintain or improve production and profits. The adoption of new methods and technologies that preserve profitability is important for the economic sustainability of farmers in the High Plains. University research is a traditional method of identifying best management practices that may improve grower productivity and profit. However, dissemination and implementation of research across broad geographies can be a measured process. The scientific method often precludes investigation across a diverse set of variables common within and across farms. Private industry can augment implementation of profitable best management practices, discovered in traditional research, by employing resources necessary for plot placement and demonstrations across wide geographies over multiple years. Furthermore, spatial and temporal investigations can be instrumental in prompt identification of processes and practices that improve producer efficiencies and/or profitability. Objective The objective of this study was to identify the fertility program components that are most critical for high yield corn. It involves: • What fertilizer is best for high yields, especially in no-till and strip-till? • What combinations of pop-up and 2 x2or2x0arebest,especiallyinno- till or strip-till or early planting in cold weather soils? • What form of application is best for positional availability in strip-till and no-till? Methodology Test plots. Plot width varied, but most strips were 6-, 8-, or 12- rows wide and spacing between rows was approximately 30 inches. Row length usually ranged from approximately 2,600 Russell French, Robert Bowling, Alyssa Abbott , and Mike Stewart Summary: The rapid adoption of new methods and technologies that preserve profitability is important for the economic sustainability of farmers in the High Plains. The work and investigation summarized in this article will demonstrate the use of spatial and temporal observations to identify best management practices for multiple nitrogen (N) applications through corn development. ▼ DOWNLOAD Starter Fertilizer @ V6
