Monday paper: Modelling microbial exchanges between forms of soil nitrogen in contrasting ecosystems
Pansu, M., Machado, D., Bottner, P., and Sarmiento, L.: Modelling microbial exchanges between forms of soil nitrogen in contrasting ecosystems, Biogeosciences, 11, 915-927, doi:10.5194/bg-11-915-2014, 2014. The questions It is well known that N and C combine to form organic molecules due to biological processes, although they come together from different pathways. C is extracted from carbon dioxid ...[Read More]
Will drinking tea get us thinking about soils? Yes, but only if you help us spread the word!
Taru Lehtinen PhD candidate at the Faculty of Life and Environmental Sciences, University of Iceland tmk2@hi.is The Tea Bag Index Project wants to create a global map on decomposition with the help of citizen scientists. We use teabags to collect vital information on the global carbon cycle. With our protocol (see our web page and our article: Keuskamp et al., 2013), citizen scientists worldwide c ...[Read More]
