1. Repurposing Zinc from Mining Tire Waste to a Fertilizer ResourceZinc (Zn) deficiency is common on high pH soils when growing field crops like Corn, Barley and Wheat. Not only are crop yields and quality limited by low Zn, but more importantly the dilution of Zn in food stuffs and, thereby, Zn deficiency in the human diet has become a major concern as recognized by the World Health Organization. At the same time, there is a Global problem in proper repurposing/disposal of used tires that contain between 1-3% ZnO. In fact, in Chile, the... K. Greer, J. Wiebe, E. Bremer |
2. ManureDB: Creating a Nationwide Manure Test DatabaseManure nutrients serve an important role in crop production, however compared with commercial fertilizers there is a lack of standardized information. When exact manure values are not known, manure book values have been referenced. Recent data from midwestern United States (US) labs indicates manure nutrient levels have changed from book values published by Midwest Plan Service (2004) and American Society of Agricultural and Biological Engineers (2005). Manure laboratory analysis has improved... N.L. Bohl Bormann, M.L. Wilson, E.L. Cortus, K. Janni, K. Silverstein, L. Gunderson |
