1. Cover Crop Suitability for High Altitude Specialty Crop Organic Food ProductionThere is a growing interest in certified organic, specialty crop food production. With a larger population demanding organic products and organic products offering a higher premium for the producer, farmers are exploring the transition to organic farming. Organic producers in southeatstern Wyoming face multiple challenges in environments with high elevation, low precipitation, and have a short growing season. These challenges include management of persistent weeds, maintaining biodiversity, and... E. Moore, U. Norton |
2. Phosphorus Efficiencies of Liquid P Fertilizers as Evidenced by P Adsorption Isotherms of Western Calcareous SoilsThe high levels of free lime or calcium carbonate (CaCO3) in arid Western U.S.A. soils reacts with phosphorus (P) fertilizers to form Ca-P minerals that are not available to plants through P fixation. Enhanced efficiency P fertilizers may potential decrease P fixation. The objective of this study was to identify P fixations levels associated with several enhanced efficiency P fertilizers on a basic soil (pH 8.03) over a 1-, 3-, and 7-day time period, and to use that data to adjust P fertilizer...

3. Soil Greenhouse Gas Dynamics in Response to Dairy Manure Compost in an Almond OrchardApplication of dairy manure compost in soils under almond production may confer benefits such as increased carbon sequestration, improved crop nutrient use efficiency, and reduction of greenhouse gas emissions. Elucidating the mechanisms of greenhouse gas emissions and mitigation is a primary concern in the management of agricultural soils and it is directly linked to nutrient management. Presently, agricultural soils account for 11.2% of U.S. greenhouse gas emissions. Of particular concern is... A. Coyotl, J. Murch, S.S. Khalsa, W.R. Horwath |
