ILF to move to weekly webinars

     In these challenging times when field days and in-person gatherings are postponed, and we all adjust to the new reality of social distancing, Iowa Learning Farms (ILF) will host weekly webinars each Wednesday at noon.

     These new weekly webinars will supplement the regular monthly webinar series hosted by ILF and allow us to continue providing timely education on issues related to water, soil, wildlife, and other conservation topics.

     The first weekly webinar, on Wednesday, March 25, will focus on carbonate research and the potential for carbon storage in Iowa soils.

     Wind-blown loess soils of western Iowa contain a significant amount of calcium carbonate in the form of the mineral calcite. These soils are naturally calcareous due to the calcium carbonate that formed from minerals originally deposited in glacial parent material. Some carbonate is present in the form of carbonate nodules, which can readily be seen in the soil profile. How much carbon is stored as carbonate in Iowa’s soils? Are there land management practices that degrade or stimulate carbonate deposition? Mark Rasmussen, Director of the Leopold Center for Sustainable Agriculture, will discuss these questions, as well as other aspects of the research being done on carbonate, during this webinar.

     “We are interested in these nodules because carbonate minerals form one of the largest reservoirs of carbon on the planet and these minerals play a significant role in the long-term balance between atmospheric carbon and climate,” said Rasmussen. “A major focus of our study is to understand the biological and chemical processes that result in carbonate formation including the carbon source used in its formation.”

     To participate in the live webinar, shortly before noon March 25:

     Visit https://iastate.zoom.us/j/364284172. Or, join from a dial-in phone line: 312-626-6799 or 646-876-9923.

     The webinar will also be recorded and archived on the ILF website, so that it can be watched at any time. Archived webinars are available at https://www.iowalearningfarms.org/page/webinars.

     A Certified Crop Adviser board-approved continuing education unit (CEU) has been applied for, for those who are able to participate in the live webinar. Information about how to apply to receive the credit (if approved) will be provided at the end of the live webinar.
