Efficient use of renewable energy:

• Wind Power for Irrigation Pumping
• Wind Power for Domestic and Livestock Water Pumping
• Wind Turbine Performance
• Wind / Hybrid Generating Systems
• Effects on Sprinkler Irrigation
• Microclimate
• Plant-Water Relationships
• Anaimal Waste Management

Efficient use of manure management:

• Decrease potential environmental hazards associated with animal feeding operations
• Develop techniques to reduce emissions and transport of ammonia from beef cattle feedyards using improved nutritional, and management practices
• Determine and improve the feeding value of byproduct feeds produced from sorghum-based ethanol production
• Develop methods to improve the utilization of and decrease the excretion of nitrogen, and phosphorus by feedlot cattle
• Develop practical feeding and management practices which will decrease the quantity and improve the quality (i.e. increase N:P ratio) of feedlot manure without adversely affecting beef cattle production efficiency

Efficient use of renewable energy:

• Wind Electric Pumping Systems
• Wind Turbine Performance
• Wind/Hybrid Generating Systems

• Dairy and feedyard particulate aerosols both PM2.5 and PM10.
• Dairy bioaerosols (bacterial and fungal) of:
  1) Milking parlors
  2) Pen boundaries
  3) Commodity barns
  4) Composting field
• Recognize and reduce emissions of hazardous particulates and bioaerosols.
• Potential health effects of aerosols and bioaerosols.
• Efficient management and safe use of manure and wastewater.
• Bovine Respiratory Disease Complex.
