Abstract

Changes in the soil temperature and solute concentration occur continually under
natural field conditions. Examples of the variations in solute concentration are
given in chapter 14, particularly Fig. 14-13 and 14-14. In addition to this type of
change induced by moisture flow, the concentration of the soil's solution oscillates
between saturation under dry conditions to very dilute values after a rain or
irrigation. Soil temperature, like solution concentration, continually changes. Its
variation is conveniently classified as diurnal (Fig. 13II-1) and seasonal (Fig.
13II-2). The diurnal thermal changes are generally significant to a depth of 20
or 30 cm; the soil zone which contains the greatest proportion of plant roots. The
seasonal temperature wave extends well below the zone of most crop roots.
