We conducted an investigation to study the relationship of soil fabric and particle-size distribution in a Davidson soil. Samples were taken from genetic horizons of five pedons of a Davidson soil located at different locations in the Southern Piedmont of Georgia. Thin sections were prepared, and analyses were performed to determine particle-size distribution and bulk density. The Normal Related Distribution Pattern (NRDP) of the soil fabric was determined by superimposing the particle-size distribution data on a NRDP triangle. Three types of NRDPs were detected, and we present a proposal to classify them (in the order of increased plasma content) as (1) phyrograni-, (2) granophyri-, and (3) plasmi-porphyric. There was a tendency for the Ap horizons to be characterized by a phyrograni-porphyric; the Bt1 and Bt2 horizons by a granophyri-; the Bt3, Bt4, and Bt6 horizons by a plasmi-; and the BC and C horizons by a granophyri-porphyric fabric. The occurrence of a particular NRDP in each soil horizon was confirmed by statistical analysis. There was a close relationship between clay contents and types of NRDP. More research is necessary for a definite conclusion on this matter. Once the correlation between particle-size distribution and NRDP is firmly established, types of soil fabrics can be determined simply by determining particle-size distribution and projecting the data in a NRDP triangle.
