1. Is Mitigation of Drought Stress By Zinc Oxide Nanoparticles Driven By a Nano-Specific Mechanism or Alleviation of Micronutrient Deficiency?It has been reported that zinc oxide (ZnO) nanoparticles (NPs) can promote drought tolerance in crops when used as soil amendments. However, many of these experiments were conducted in Zn-deficient growth media with no comparison to currently available Zn fertilization methods, making it unclear if the benefits from adding ZnO NPs were caused by a nano-specifc mechanism or simply by the mitigation of a micronutrient deficiency. A review of the literature shows that of 12 published experiments... J.W. Deakin, M. Potter, A. Cartwright, J. Hortin, D. Sparks, J.E. Mclean, D.W. Britt, A.J. Anderson, A.R. Jacobson, L. Yen |
2. Application Timing, Soil Type, and Source Effects on Elemental S AvailabilityThe reduction in acid rain due to increased regulation of manufacturers in the U.S. has led to S deficiencies in agricultural crops. In response, elemental sulfur (S) fertilizer products are becoming more widely available to growers, but have not been evaluated for their S availability and S oxidation characteristics. The objective of our research was to evaluate the S availability and S oxidation rates of five elemental S fertilizer products. The evaluation was done using two Oregon soil types... A. Cox, A.
