| First Communication Post-Workshop 19 Dec 07 | First Post-Workshop Communication 19 December 2007 We will not soon forget last week’s warm Carolina-December days. Many thanks to each of you, especially for your active participation! A workshop participant list with contact information will be emailed within a few minutes of this being posted. | |||

| Humanity as soil transformers | Uncorrected galleys from Soil Science. | |||
| Potential cross-site research at multiple LTSEs | To investigate temporal changes in soil systems with respect to management treatments, soil taxa, novel and highly significant cross-site studies can be conceived, based on previously published data available in the literature, or on samplings from contemporary collections or from sample archives. Themes for the cross-site proposals include: N, P, etc. mineralization and in-soil cycling Fractions of phosphorus, and bioavailability of slow-cycling pools of P Soil carbon fractions, including stable and radio-isotopes. | |||
| The Use of Archived Soils in Microbiological and Environmental Research | Not only long term experiments themselves are a rich source of information, archived soil samples can yield valuable information too. Reanalyzing archived samples for historical trends in e.g. PCB levels is an accepted approach (e.g.: Alcock, R.E. et al. 1993. Environmental Science and Technology 27: 1918-1923). We recently used PCR-DGGE on historical soil samples from long-term field experiments and observed systematic differences between samples from soils that had received different treatments. | |||
| YOU define LONG TERM! | YOU DEFINE "LONG TERM": whether a LTSE has been sampled meticulously for >100 years such as some of Rothamsted's studies, or a study has just been sampled for the first time but has ambitions to last for 200 years (e.g., the Vermont-USA LT Soil Monitoring Study). The users of the LTSE database can sort by duration of study, so YOU define "long term". DDR |
