| What are key findings that can be discovered only in long-term soil studies? | Much of the world’s food supply is produced in intensively managed cropping systems that involve high inputs and high outputs. As our populations continue to increase while the amount of arable lands steadily shrinks, these intensive systems assume greater importance. Can they be maintained into the indefinite future? Will they continue to supply high yields of our foodstuffs? Answers can be gained solely through long-term field studies. | |||
| Why do I work on long-term sites? | I began work on long-term sites, not by wise and deliberate choice, but by fluke of serendipity: when I arrived in Lethbridge as fledgling scientist, historical plots established there in 1911 were assigned to me. So a better question might be: why do I keep on working on these sites? In pondering the question, three fragmentary responses emerge. | |||
| New report on the Sanborn Field Experiment | Hello folks, While looking up the results of a short term soil fertility study in an annual research report, I was very surprised to find a nice report on the 3rd oldest agronomic experiment in the world ! Click on the following link and go to page 6. Do we have anyone associated with Sanborn Field participating in this network ? Joel | |||

| Telling the story of archived samples from LTSEl | Hello folks, The current issue of Nature has an editorial (appended below) that made me think of the archived samples at Rothamsted. I am not too concerned about Rothamsted sending its 200,000+ bottles to the landfill (or giving them as "amusing gifts to visiting scientists") but surely there are soil archives that have gotten too unwieldy and are at risk.... or that have already been jettisoned. Perhaps we can make sure that Nature's new monthly series pays homage to an at-risk archive of soil samples (or other materials) from a long-term experiment... Any thoughts ? Joel | |||

| V. Romanenkov: What key findings can only be discovered in long-term soil studies? | My opinion that many preferences of LTEs can be assessed in a network study and we are lucky to use such network principles from the very beginning of LTEs foundation in the former USSR since mid 30s last century in agronomic research. This approach was realized in a series of publications which define the unified system of indicators, sampling protocols and analytical methods. | |||
| D. Powlson: Why am I working on long-term sites? | David Powlson, Rothamsted Research, UK • I started my career in soil science working at Rothamsted Research, UK. This is the site of several long-running experimental field sites, the oldest being the Broadbalk Wheat experiment started in 1843. It was originally designed to compare crops yields achievable from (the then newly developed) chemical fertilizers with those from animal manure. In its first few decades the experiment laid the foundations for our current understanding of plant nutrition. | |||
| Abbreviated list of menu items for LTSEs (experiments and comparative studies) | Vladimir had another one of his invaluable: "one other idea not to forget"!! If I understand, Vladimir suggested that we consider splitting the website's metadata in two tiers. | |||
| Potential Project/Paper on Sample Archiving | Recently Arlene Tugel and Garrett Liles (student at Davis) mentioned interest in sample archiving. This should be (if it isn't already) on our list of potential new projects/papers for our network. This is an absolutely great topic that could be explored much more than is in the literature currently. Extremely important. Dr. Poulton at Rothamsted has some information on Rothamsted practice and I will get permission to post and share these!! Dan Richter |
