Water quality is defined in terms of the elemental composition and concentration of salts dissolved in the irrigation water. The ratio of precipitation to potential evaporate-transpiration varies seasonally in arid and semi-arid climates. Salinity is a common problem in poorly managed container nurseries when fertilizer salts are allowed to build up in the medium without adequate leaching, but is not usually a problem in bare-root nurseries. Salts injure bare rootstocks in the following ways.
Osmotic stress
The following values are often used to access the effects of salts on growth
