Degradación química en Acrisoles bajo diferentes usos y pendientes en la sabana de Huimanguillo, Tabasco, México

Abstract

Objective: To evaluate the chemical soil degradation caused by nutrients lost in Acrisols from the Savannah of Huimanguillo, Tabasco, Mexico.

Design/methodology/approach: The effect of two factors, land use and slope relief, were study. Properties evaluated were soil organic matter (SOM), total nitrogen (Nt), available phosphorus (P), Cation Exchange Capacity (CEC), and exchangeable cations (K, Ca, Mg, Na).

Results: The content of SOM were considerate rich to very rich, and did not showed any significant differences between factors. Nt was statistically high, and K was statistically low. P, CEC, Ca, Mg and Na showed statistically differences and lower contents.

Limitations of study/implications: Soil degradation is a global problem, therefore the necessity of studies to understand the effect of land use over soil fertility and land chemical conditions.

Findings/conclusions: The results indicates presence of chemical degradation in Acrisols, mostly by effect of land use and suggest the necessity of conservation strategies.
