Documents below include results of post flood soil tests, kindly donated by Nutri Tech.

  1. Graph showing how our results in Oct 2010 (Green) and Jan 2011 (Yellow) compare to the recommended levels for each element.  Also included on the graph are notes re sources of elements (courtesy of Bruce Ham of BOGI) and suggestions for soil management practices at Jane Street.
  2. Detailed spreadsheet figures showing both Oct 2010 and Jan 2011 test results with percentages of recommended levels.  The Oct 2010 results included Total Saturation as well as leaf tests, which were not included in January results.
  3. Page 2 of above spreadsheet shows Contaminant levels measured post flood - all of which are below 0.1% of the recommended levels, ie insignificant.
  4. Bruce Ham's list of organic products providing some of the soil elements.

A separate discussion has now been posted showing the complete Nutri Tech report, which includes 16 pages of general information about soil elements, availability relevant to pH, interactions between different elements.  While it also includes a lot of product promotion, I found it very helpful as a summary of all the soil elements and how they relate to each other.

If you find these documents hard to read, there are a couple of options.  

  1. Click on the document, which will take you to a full size view, which you can enlarge, or

Or email me and I'll send you copies.

Interesting. Are you going to lay off the manure to bring down the zinc and phosphorus?

I expect this kind of test is usually quite expensive - would be interesting to have it done of our own soils if it was cheap.

No report on contaminants left over by the flood?
