Question

A soil scientist collects a sample from a field that has been continuously irrigated with poor-quality water over many years. On testing, the soil shows a high concentration of soluble salts in the soil solution and a high electrical conductivity value, but a near-neutral pH and good soil structure that has not been significantly damaged. Based on these characteristics, which type of problem soil is this field most likely to be?

Saline soils are characterised by a high concentration of soluble salts and a correspondingly high electrical conductivity, but generally retain a near-neutral pH and relatively undamaged soil structure, unlike sodic alkali soils, which have high exchangeable sodium, high pH and poor structure caused by dispersed clay particles.
