This book was released on 2005 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guidelines, or recommendations, for nitrogen (N) management in the Corn Belt are important to corn producers because fertilizer N must be applied for profitable corn production, because profit margins are narrow, and because N fertilization has been linked to local and regional water quality problems. Producers rely on these recommendations because it has been impractical for individuals to identify optimal rates, times, and methods of N fertilization for corn. Precision farming technologies, however, enable organized networks of crop producers to evaluate management practices used on their farms and within regions. These technologies and on-farm trials were used to assess optimal rates of spring-applied and sidedressed N, assess the benefits of using a nitrification inhibitor, and assess the ability of injected liquid swine manure to supply N needed for corn growth. The results showed optimal rates of N were less than currently recommended rates, nitrification inhibitors did not increase profits for producers in central Iowa, and injected liquid swine manure at normal rates supplied adequate amounts of N for plant growth. The results suggest that current recommendations could be substantially improved. The results document that organized networks of producers working together can evaluate and improve nitrogen management and thereby increase their profits while reducing environmental problems associated with N fertilization.

Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.

Download or read book Early Season Losses of Fertilizer Nitrogen During Corn Production written by Kipling Shane Balkcom and published by . This book was released on 2000 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third study involved use of precision fanning technologies in field-scale trials to evaluate the importance of N losses when farmers apply N only in the fall. The importance was evaluated by applying extra N in strips and measuring crop responses to this N. Large responses to the extra N were detected, and these responses suggest that losses of fall-applied N resulted in severe N deficiencies and costly yield reductions. The results of each study provided compelling evidence that early season losses of N are important during corn production in Iowa and that these losses could be substantially reduced by delaying N fertilization until plants are growing. The benefits of this change would include greater profits for producers and less environmental degradation associated with losses of N from fields. The results suggest that these benefits could be obtained if farmers used the new soil and tissue tests in organized programs designed to evaluate and improve the outcomes of N management on their fields.
Download or read book Nitrogen Management of Corn with Sensor Technology written by Andrew Neil Tucker and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn (Zea mays) is an important cereal crop in Kansas primarily used as livestock feed for cattle in the feedlots, and there has been increased use of corn for ethanol production as well. According to the USDA National Agriculture Statistics approximately 1.7 million hectares of corn is planted each year in Kansas, with an average yield ranging from 5,750-7,750 kg ha[superscript]-1 within the last five years (2005-2009). With this variability in yield and volatility of crop and fertilizer prices over that same period, it seems logical that optimum nitrogen or N rates may vary. A series of 14 field experiments were conducted across Kansas from 2006 through 2009 to address this issue. Specific experiments included: evaluating optimum N rates from side-dressing nitrogen fertilizer; timing of nitrogen application, pre-plant vs. split applications and normal side-dress V-6-V-9 vs. late side-dress V-14-V-16; N response of corn to a late side-dress of nitrogen fertilizer; and the evaluation of optical sensors for making in season N recommendations. The specific objectives of this research were to: a. Determine the optimum N application rate and timing to optimize corn grain yields in different corn producing regions in Kansas. b. Confirm or revise the current K-State soil test based N recommendation system for corn. c. Evaluate N management strategies using the GreenSeeker, Crop Circle, and SPAD meter, crop sensors. d. Develop draft GreenSeeker, Crop Circle, and SPAD sensor algorithms for producers to use. Grain corn yields were responsive to N at all but 3 sites. Grain yields obtained at the sites ranged from 3,460 to 15,480 kg ha[superscript]-1. Optimum N rates varied from 0 to 246 kg N ha[superscript]-1. This work suggests that current K-State N fertilizer recommendations for corn need revisions due to over recommendation of N. Including different coefficients for irrigated and dry land corn along with N recovery terms would create a more accurate N recommendation system that more closely reflects the results obtained in these experiments, and provide a significant improvement over the current system. The optical sensors used in this study were effective at making N recommendations for corn. These sensors can be a valuable tool for producers to use and determine in season N status of corn.
