PLANTS ADAPTED TO VARIOUS TYPES OF SOIL CONDITIONS : Page 470

Since in a light, sandy soil the particles are relatively large such asoil is generally well aerated and not retentive of moisture. Thus,plants adapted to such a soil are as a rule very hardy and possessed of alarge root system due to the fact that the roots generally have to ex-tend considerable distances in search of water which may fail justwhen most needed, that is, during summer droughts and winter freeze-ups accompanied by a drying wind. Also since this soil type is wellaerated it is not likely to contain much humus or to be acid in char-acter as the aeration or oxidation of the humus removes one cause of thesoil acidity.
