6.4 Soil Salinity

Soil salinity refers to the concentration of salts found in soil water. Common soil salts include chlorides like sodium chloride and calcium chloride, as well as some carbonate compounds like lime (calcium carbonate) and sulphate compounds like gypsum (calcium sulphate). Salinity is closely related to soil conductivity as dissolved salt ions are the primary source […]

3.2 Conductivity, Salinity and Total Dissolved Solids

Conductivity, often denoted as EC (electrical conductivity), is a measure of a water sample’s ability to conduct electric current. It is primarily determined by the presence of dissolved salts and other inorganic substances that ionize in water. Such substances are known as electrolytes, and they conduct electricity due to their positive and negative charges.   The […]
