1) Did they test specifically for pathogens, or only for E Coli in
2) In how many different locations, and in how many different years,
did they run the tests?
3) Do they know of other studies done in this area, and what were the
results of those studies?
4) Have they themselves done, or are they doing, other studies in this
area? If any others are completed, what were the results?
5) Were all results from all studies they know of published, or only
selected studies and/or results? If only some, what were the selection
6) What were the climate and weather conditions?
7) What were the soil types?
8) What was the organic matter content of the soil, and what was its
other nutrient balance?
9) Had the plots previously been organically managed or conventionally
managed? For how many years had they been so managed? If they had not
been in farm use, what was the previous use for the past few years?
10) Were the plots conventionally or organically managed during the
11) What was applied to the plots during the trial besides the manure
and seed? (including all soil amendments, pesticides, any
12) What had been applied to the plots during the previous couple of
13) What tillage and harvest techniques were used?
13) What, if any, tests were done to determine what other life
(bacterial, fungal, worm, etc) was in the soil? If any were done, what
were the results?
14) In addition to soil life, what living creatures had access to the
field during the trials?
15) Was irrigation used? If so, what was the source of irrigation
water, and what if any tests were done on it?
That should do to go on with . . .
(I should note that at least some of this may well be answered in the
study itself. If little or none of it is addressed in the study, that
would be a huge red flag in itself.)
