In this study, the altitudinal distribution pattern is described and the importance of soil color as a distinctive property and its relationship to chemical properties were evaluated in Leptosols in the henequen zone in Yucatan, Mexico. Two altitudinal transects across the micro-topographic gradient were carried out, with samples taken at 1.5 m intervals. Soils were sampled at a depth of 0 to 5 cm and 5 to 10 cm. Three soil types were found covering three Mayan classes: red (R), Haylu'um; reddish brown (CR), Chaclu'um; and black (NE), Boxlu'um. Organic matter, Ca, and P were the chemical properties related to soil color and the altitudinal gradient pattern. The R soil had low organic matter, Ca, and P, intermediate values in CR, and NE showed higher values. The R soil contained more particles 2 mu or less in diameter of minerals such as hematite and halloysite than NE, and CR is an intermediate grade. The content of total oxides also follows the sequence R > CR > NE. Microtopographic position and soil color can be used as distinguishing properties related to the chemical and mineralogical properties.
