Fluid Journal : Late Spring 2012
FLUID JOURNAL ARTICLE ARCHIVES 18 years of agricultural research and studies available, dating back to 1993, the inaugural date of the Fluid Journal. Spanning our first year, 3,850 visits and 81,034 page views in 28 countries since we’ve joined the Realview web. We publish 4 times a year, each edition packed with valuable agronomic research that will help you maximize yields. Visit our archives at: www.fluidfertilizer.com Extreme heat and drought during the spring and summer drew soil moisture from depth, likely contributing a great deal of additional NO3 during periods of stem elongation through grain fill. The lack of consistent grain protein results from the Lahoma location tends to support this hypothesis. While there was significant difference in mixing tolerance scores across treatments at Lahoma, no conclusions can be drawn on which timing rate or source may lead to an improved score above the standard fertility treatment. Loaf Volume results were very positive and indicated a potential increase in volume with foliar applied N. While results were not consistent across sites, the data do suggest that N applied post-anthesis may lead to a higher likelihood of volume increase. The 2011-2012 winter wheat crop is in the ground with a good stand at both locations. The forthcoming results are highly anticipated as an added year of data will likely lead to a better understanding. Figure 5. Mixing Tolerance Score results from the grain collected at the LCB, OK location. Hard winter wheat Quality Targets Committee recommends a target value of 3 or greater. The horizontal line shows the recommended level. Treatment titles shown as nitrogen rate in kg N ha-1, nitrogen source, and application timing. Figure 6. Loaf Volume, measured in cc, results from the grain collected at the LCB, OK location. Hard winter wheat Quality Targets Committee recommends a target value of 850 cc or greater. The horizontal blue line shows the recommended level. Error bars represent standard error of each treatment.
