1. Emissions of Ammonia and Greenhouse Gasses from Dairy Production Facilities in Southern IdahoIdaho is one of the top three milk producing states in the United States. While this commodity group is a very valuable part of the economy, there is concern over the impact of these production facilities on the generation of ammonia (NH3) and greenhouse gases (methane, CH4 and nitrous oxide, N2O) which are linked to air quality degradation and global warming. To gain a better understanding of the on-farm emissions from these production facilities, we monitored both cattle housing and manure... A.B. Leytem, D. Bjorneberg, R.S. Dungan |
2. Dairy Manure Applications to Potatoes: Soil Property, Plant Nutrient, and Tuber Quality ResponseDairy manure applications have become a common practice in Idaho potato production, however the impacts on soil and plant agronomic properties are not well understood. Our objectives were to determine (1) how repeated dairy manure applications impact soil properties and plant nutrient uptake, and (2) how these changes influence plant nutrient interactions, tuber yield, and quality. Stockpiled dairy manure was fall-applied over a 6-year period to two adjacent potato production... A. Moore, A.B. Leytem |
3. Predicting Nitrogen Mineralization from Dairy Manure in Semiarid Cropping SystemsTools are needed to estimate N mineralization from application of dairy manures in semiarid irrigated soils. We found that N mineralization was affected by manure application rate, timing and broadleaft residue N. Average N mineralization was 27 and 18% of the N applied the 1st and 2nd year following application, respectively. The best predictors of N mineralization were soil organic matter, soil EC, manure N and broadleaf N residue. ... A.B. Leytem |
