1. Polymer Coated Urea (ESN): Impacts on Potato Crop and N LossesPotato (Solanum tuberosum L.) production is sensitive to a steady, adequate supply of nitrogen (N). Synergistically optimizing grower profits while maximizing N use efficiency (NUE) is critical to conserve nonrenewable natural resources used to manufacture N fertilizer and minimize N pollution to water and the atmosphere. Polymer coated urea (PCU, Environmentally Smart N or ESN®) is one type of N fertilizer which uses temperature-controlled diffusion to control N release to better match plant... B. Hopkins, C.

2. Deficit Irrigation in Vineyards of Washington StateIn Washington State the primary wine grape producing areas lie within the rainshadow of the Cascade Range and receive little precipitation throughout the year and especially during the summer. Wine grape producers take advantage of the arid conditions and use irrigation management to control vine growth and vigor. The precise control of irrigation timing and amount also affects the wine making characteristics of the fruit produced. A Cabernet Sauvignon (Vitis vinifera L) vineyard was used... B. Riley, R.

3. Residual Soil Nitrate and Potato Yield with Polymer Coated UreaPotato (Solanum tuberosum L.) requires steady, but not excessive nitrogen (N) supply for maximum tuber yield, size, and solids, as well as minimal internal and external defects. Although more costly and labor intensive than dry broadcast applications, growers typically apply a majority of N via fertigation. A controlled release N fertilizer, polymer coated urea (PCU), is a possible alternative to this growers’ standard practice. A newly formulated PCU may meet plant demand... B. Webb, B. Hopkins, J.
