Effect of land use change on the edaphologic propierties in la sabana, Huimanguillo, Tabasco, Mexico.

Abstract

Objective: Evaluate physical and chemical properties of acid soils subject to change of land use in La Sabana of Huimanguillo, Tabasco, México.

Design/methodology/approach: The following technical criteria were used: production systems representative of savanna soils in Huimanguillo, Tabasco, from sugar cane (Saccharum spp.), pineapple (Ananas comosus L.), cassava (Manihot esculenta Crantz), pastureland, and acahual (secondary vegetation). Physical and chemical properties were evaluated using standardized methods: apparent density (AD), organic matter (OM), total nitrogen (N), extractable phosphorus (P Olsen), cation exchange capacity (CEC), electric conductivity (EC), exchangeable bases (K, Ca and Mg), and pH.

Results: Results suggest highly statistical differences in contents of OM, AD, pH, and porosity (%). Statistical differences were found in Ca, Mg, and K content. Total N, P Olsen, CEC and EC, did not show statistical differences.

Study limitations/implications: La Sabana of Huimanguillo, has been affected by a significant loss of soil fertility, therefore is important to evaluate the soil degradation process by change of land use under different climate conditions.

Findings/conclusions: Evaluation of soil properties degradation in acid soils subject to different land use, physical and chemical properties of soils showed that sugar cane and pastureland were affected significantly.
