Abstract

: Root development and water movement in the soil profile are highly affected by the shape, size and orientation of the soil pores. The high spatial and temporal variability of soil porosity required a quick and repeated non-distruptive technique to measure it in order to develop a more suitable land management recommendation. The use of computed tomography (CT) scan, which has been used for years in medical examination of patient, can be utilized in quantifying rapidly and accurately soil porosity and other soil characteristics as well as root development in the soil sample. The advantage of CT scan technique over other techniques such as soil water characterictis curve and thin section is the possibility to quantify the amount, spatial distribution, fractal dimension, and shape of the soil pores from 3-D high resolution image produced. The aim of this review is to offer a perspective on the possible application of CT scan technique in soil porosity and root studies to obtain more detail understanding of soil and root interactions. With that understanding, one can develop more accurate soil and crop management to improve agriculture productivity.
