For the soil sorption experiments, three types of soils that varied
in terms of texture, OC content and the rate of the OMW application
were sampled from olive orchards in the Negev (southern
Israel): a sandy clay loam from Gilat, a silt loam from Negba and
a sandy clay loam from Revivim. In each case, soil was sampled
in triplicate from the 0–3 cm top layer in the area affected by the
local OMW disposal and in a control area which were selected to
minimize differences except OMW application. The 0–3 cm layer
was selected following the work by
