Looking Ahead to October: Avian Influenza Mortality Management

What are some of the lessons learned about mortality management during the 2015 avian influenza outbreak? Three specialists that spent time in the field assisting with disposal efforts will summarize their experiences during this presentation. The webcast will provide a current update of the outbreak and highlight mortality management options. An emphasis will be placed on proper  mortality composting procedures and provide ideas for preparation in case a recurrence of the disease occurs this fall. More...

cow grazingGrazing Management. Management Intensive Rotational Grazing (MIRG) was compared to continuous grazing, mechanical harvesting, and no management in a Wisconsin study in terms of forage quantity and quality, carbon sequestration, and soil microbial community. In one year of the study MIRG lost less carbon than the other treatments, and in the second year it sequestered more carbon than the others. They also concluded that differences in grazing productivity were due to impacts on plant physiology and not on soil microbes. Both grazing treatments also tended to increase the availability of nutrients compared to the mechanical and non-managed treatments.  More...

Nutrient Management

  • Michigan State University Extension reminds producers to take credit for nitrogen in previous years' applications and legume crops when planning for nutrient application. More...
  • A global research network examined the response of soil microbes in grasslands to the additions of nitrogen and phosphorus fertilizers. Not surprisingly, the populations shifted between soil fungi, bacteria, and soil organisms and that these shifts seem to be consistent globally. More...

“These shifts are somewhat predictable, and this helps us to understand how human activity can affect microbial communities in the soil, something that isn’t very well understood,”

International view.

  • Most of us are aware that nitrogen use efficiency is a key fulcrum around which water quality, air quality, and greenhouse gas emissions revolve. Denmark has passed many nitrogen-related regulations over the past 25 years. Researchers looked back and created a national nitrogen budget to identify potential areas of imbalance and opportunities for re-use or greater efficiency. An interesting conclusion is that nitrogen emissions have been reduce but that the agricultural sector remains a major contributor. For this industry, the easy changes have been made and it may be beneficial to look at other sectors for inexpensive fixes before asking the ag sector to take on more expensive changes.

bottles of veterinary pharmaceuticalsAntibiotic Resistant Bacteria. California legislators has passed a bill that would require a veterinary prescription for using antibiotics in animal production. While the bill bans use of antibiotics for 'growth promotion', most environmental groups oppose it because they believe it will not actually reduce antibiotic use. The prevailing feeling is that the term "growth promotion" will be replaced by "disease prevention" on labels.  More...
