The objective of this study was to develop a practical method of soil sampling able to maintain the natural structure of the sample unaltered. The sampling device developed in the study consisted of fixed and movable parts. Field tests were performed to evaluate the ability of the developed sampling device to take soil samples with their structure unaltered. Also, soil hydraulic conductivity in saturated media was determined from samples collected using different methods. Samples which were taken using the method developed in this study, i.e. with their structure unaltered, had higher values of hydraulic conductivity than sieved and repacked samples or than those taken using the Uhland sampler. Thus, the soil sample with its natural structure unaltered is more appropriate as it represents more accurately the field conditions. © 2014, Universidade Estadual Paulista - UNESP.
