There are some 0's that must be retained: CaCO3 and EC, and SAR.
Investigating om_r
values equal to 0. There are very few cases where 0% organic matter is possible.
Fortunately, there are only 63 records with A horizons with 0%
organic matter.
select component.areasymbol, compkind, compname, hzname, om_r from ssurgo.component JOIN ssurgo.chorizon USING (cokey) where om_r = 0 AND hzname ~~ 'A'
A couple of examples:

Apart from rock fragment volume, there aren't many cases were a 0 in the horizon or component data makes sense. These values should be:
Filtering will be required at the horizon and component levels.
