Subject: RE: Reduced Rates of Fertilizer -- Mark, Pat


mhagny, The soil tests that increased in OM were in 19 different fields, all with the same soil type(Mexico silt loan), and mostly level. Our soils dont vary much here---we're on a prairie and the whole county has basically the same soil. Field after field in this area during the eighties had OM levels of 1-1.5%. The whole area was conventional tillage and probably 2/3to3/4 soybeans. Not a good combo for OM. That's when we started changing practices. All those 19 original fields were probed 6 in. deep with multiple probes in each sample and all were always sent to A&L labs in IN. None of these fields were over 1.5% when we started changing practices except for a field that had come out of sod. Not trying to argue--just trying to learn.
