1. Developing a Soil Health Assessment Framework for Specialty Crop Systems and Soils of Washington StateTo ensure productive soils, agricultural sustainability, and food security, it is vital to maintain and improve soil health. However, over the decades, intensive agricultural practices have led to a decline in soil health. While most of these intensive agricultural practices negatively affect soil health, research has shown that it is possible to resuscitate soils with practices such as over cropping, and crop rotation. Much of the research on soil health in the US has been done in agronomic systems... K.A. Sarpong, M. Mcilquham, L. Michel, D. Griffin |
2. Differences in How Late Season Soil Vs. Foliar Nitrogen Fertilizer Supplements Affects Riesling YanDuring the 2011 and 2012 growing seasons, 0, 15, or 30 lbs/A N was applied in split applications as either soil (simulated drip) or foliar applications to a commercial Riesling vineyard with a history of low vine N. Each treatment was replicated 4 times. To assess the impact of the supplemental N applications on vine vigor, shoot lengths were measured weekly and pruning weights collected during the dormant season (2012/2013 pruning not yet conducted). Fruit was harvested within 2 days of commercial... J. Davenport, M. Mccoy |
3. Elemental Sulfur with Iron: Kentucky BluegrassIron (Fe) is known to improve greenness of Kentucky bluegrass (KBG; Poa pratensis L.), although applications are relatively costly and labor intensive. A new fertilizer material, elemental sulfur impregnated with Fe (ES-Fe), may provide an alternative source of Fe for KBG. The effects of ES-Fe on KBG was evaluated comparing 55 lb-Fe ac-1 ES-Fe to ferrous sulfate (FS) at the same rate and chelated Fe as a foliar (CF) or soil applied (CS) in a glasshouse study. A separate... B. Hopkins, B. Webb, K. Marcroft, R. Christenson, V. Jolley |
