"Webactivity clays of many tropical sandy soils. A large range of porosity Sandy soils in the tropics show a large range of porosities and consequently bulk density (D b). Porosity ranges from 33% (D b = 1.78 g cm-3) to 47% (D b = 1.40gcm-3) are commonly recorded (Figure 1). The porosity in sandy soils is usually smaller than in clayey and silty soils.

WebChanges in pore shape and size distribution were also ob- served. The proportion of large elongated pores (50-500 ~tm) was higher where the level of the water table was deeper. Consequently, the shallow water table seemed to deteriorate the soil struc- ture reducing the porosity to a level inadequate for plant development.
