ABSTRACT
Soil scientists and agricultural engineers have traditionally been interested in the behavior and e¦ectiveness of agricultural chemicals (fertilizers and pesticides) applied to soils for enhancing crop growth, as well as in the e¦ect of salts and other dissolved substances in the soil prole on plant growth. More recently, concern for the quality of the vadose zone and possible contamination of groundwater has provided a major impetus for studying solute transport in soils.
