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. Measured and Predicted Temporal Changes in Soil Nitrate-n Levels from Late Summer to Early Spring in MontanaMost soil sampling is conducted from August to November in Montana because of better soil sampling conditions and because it provides more time for growers to make fertilizer decisions prior to application. Fertilizer guidelines in Montana are based on spring nitrate-N levels in the upper 2 ft because they are more indicative of growing season available N than fall nitrate-N levels. It is not known how much nitrate-N levels change between late summer and spring, nor is it known what factors affect... C. Jones, A. Lenssen, C. Chen, K. Mcvay, B. Stougaard, M. Westcott, J.
