  • Monitoring CO2 with humidity and temperature may help detect problems in stored grain

    Grain storage bins are routinely monitored for temperature to control insect and mold problems. Now an Agricultural Research Service (ARS) scientist and his colleagues at Kansas State University (KSU) have preliminary research findings showing that monitoring carbon dioxide--along with humidity and temperature--also may help detect problems more effectively. Grain moisture content and temperature ...

  • Using respiration indices

    Respiration is directly related to the metabolic activity of a microbial population. Micro-organisms breathe at higher rates in the presence of large amounts of bio-available organic matter, while the respiration rate is slower if this type of material is scarce. In the composting process, respiration activity has become an important parameter for determining the stability of compost. It is also ...
