DETERMINATION OF HYDROLOGIC POTENTIAL IN T3-TYPE TEPETATES WITH SIMULATED RAINFALL

DETERMINATION OF HYDROLOGIC POTENTIAL IN T3-TYPE TEPETATES WITH SIMULATED RAINFALL

Several researchers have found that tepetates are more erodible when managed under an agricultural system, because they become more susceptible to the erosive process. For this reason it is necessary to know their hydrologic potential, and its ability to remove and transport sediments. Using a rainfall simulator on a T3-type tepetate, an experiment was conducted to determine its hydrologic potential, under three conditions: natural tepetate (TN) (control), subsoiling tepetate (TRR) and tilled tepetate (TI); and two rainfall intensities: 40 and 60 mm h-1 in humid and dry conditions. The results were related to sediment yield. The control (TN) resulted in higher soil losses. Poinding times in TN and TI treatments were less at the intensity of 60 mm h-1, whereas the TRR treatment presented a higher water infiltration capacity. Overall, the TN treatment presented the highest percentage of runoff and the lowest water retention capacity; therefore, this condition has a high hydrologic potential to generate runoff. TI and TRR presented moderately high and moderately low hydrologic potentials, respectively. In addition, it was confirmed that the T3- type tepetates are highly erodible.

Diversos investigadores han señalado que los tepetates incorporados a la producción agrícola son más erosionables pues están más expuestos al proceso erosivo, por lo que es necesario conocer su potencial hidrológico y la capacidad de éste para remover y transportar los sedimentos. Con tal propósito, se estableció un experimento para determinar el potencial hidrológico del suelo en un tepetate tipo T3 con lluvia simulada en tres condiciones: tepetate natural (TN) (testigo), tepetate recién roturado (TRR) y tepetate incorporado (TI); se utilizaron dos intensidades de lluvia (40 y 60 mm h-1) en condición seca y húmeda del suelo, y se relacionó con la producción de sedimentos. El TN presentó altas pérdidas de suelo. La lámina de imbibición en el TN y TI fue menor en la intensidad de 60 mm h-1, en cambio, el TRR presentó una elevada capacidad de infiltración. De manera general, el TN presentó el mayor coeficiente de escurrimiento y la menor capacidad de retención de agua, por lo tanto, su potencial hidrológico para generar escurrimiento fue alto. El TI presentó un potencial hidrológico moderadamente alto, y el TRR, moderadamente bajo. Además, se corroboró que los tepetates tipo T3 son altamente erosionables.
