La materia orgánica edáfica (MOS) influye significativamente sobre la capacidad productiva del suelo y su conservación es una creciente preocupación ambiental y económica. Para ello, es necesario entender los procesos que rigen su dinámica como es el caso de su interacción con la fracción mineral del suelo, donde el efecto de la textura sobre la acumulación de la MOS aún es motivo de controversia, lo cual fue motivo del presente trabajo. Para ello, se establecieron relaciones cuantitativas entre la MOS, contenido de partículas minerales <50 mm (FF) y superficie específica (SE) en muestras de suelo (0-5 cm de profundidad) colectadas en el estado de Campeche, México, en sitios con vegetación de selva perennifolia no perturbada por la actividad agrícola o pecuaria. Aunque se observó una relación significativa (R2=0.66; P<0.0001) entre la FF y la SE, ambas variables explicaron de manera distinta la variación de la MOS (39 %; P<0.0001 y 77 %; P<0.0001, respectivamente), lo cual se atribuye a que el vínculo entre los compuestos orgánicos y minerales del suelo está dado fundamentalmente por reacciones de adsorción.
PALABRAS CLAVE: protección; fracción fina; selva perennifolia
Soil organic matter (MOS) has a significant influence on soil capacity productivity and its conservation is an increasing environmental and economic concern. Dealing with this matter is necessary to understand the process which conducts performance as interaction with soil mineral fraction, where the effect of texture over the accumulation of MOS is a controversial matter, and will be explained throughout this work. On first hand, we establish quantitative relationships between MOS, mineral particles <50 mm (FF) and specific surface (SE) in soil samples (0-5 cm deep) collected in Campeche state, México, in tropical dry forest sites absent from agricultural and cattle activity. We observed a significant relationship (R2=0.66; P<0.0001) between FF and SE, both variables explain differently the variation of MOS (39 %; P<0.0001 and 77 %; P<0.0001, respectively), this attributed to the vinculum between organic and mineral compounds from soil, due to adsorption reactions.
KEY WORDS: protection; fine fraction; tropical dry forest
