Available in PDF, EPUB and Kindle. Book excerpt: Placement of fertilizer nitrogen (N) is a critical issue during the production of corn in no-till systems, but the effects of placement vary with many site-specific factors. On-farm trials offer a new method for evaluating the effectiveness of alternative placements. The objective of this study was to explore the potential of using yield monitors in on-farm trials to compare the effectiveness of dribbled and injected N fertilizer solutions for production of corn in no-till systems. Strip-plot trials were conducted in 16-ha to 24-ha fields to compare dribbled and injected urea-ammonium-nitrate (UAN) solutions applied after crops had emerged in 2002 and 2003. The fertilizer was applied at three rates and two times to help evaluate the effects of placement, and end of season cornstalk nitrate concentrations were measured to help interpret yield response data. The solutions were applied at 56, 112, and 168 kg N ha−1 in six-row strips that were harvested as single swaths with a yield monitoring combine. Placement had statistically significant effects on yields at only one of the six site years studied. No placement effects were observed on cornstalk nitrate concentrations at any of the site years. The effect at this site was probably caused by an unusual lack of rainfall that delayed movement of the dribbled N into the soil. Based on means over the six site years, the benefits of injecting fertilizer were small in comparison to the added time and equipment costs associated with an injected treatment. On-farm trials using treated strips and yield monitors offer an effective way for corn producers within a region to evaluate alternative methods of applying fertilizer under conditions relevant to them.

Book excerpt: This book "is written specifically for western agriculture and for individuals seeking practical, production-oriented, problem-solving information. ... Basic information is included on properties of soil, water, and plants. Fertilizer products, their properties, and their management are presented, as is related information on soil amendments and irrigation water quality. All this is framed in the context of western agriculture--that is, primarily high-yielding irrigated crops grown on soils frequently having a pH above 7.0"--Foreword.
