ABSTRACT

The soil solution plays a dominant role in the uptake of nutrients by plants, has direct impacts

on other soil-living organisms, and under certain conditions it is the vector for the migration

of dissolved and suspended materials through soils. We are defining the soil solution as the

liquid phase of the soil present in the field. This definition precludes all methods in which

salt solutions, or water, are added to a soil sample in the laboratory to simulate soil solutions

as these procedures may be more accurately defined as soil extractions.
