Islas de fertilidad en handroanthus chrysanthus, especie representativa de bosque seco

Abstract

Abstract: This study analyzed the variation of soil pH and carbon stock, as well as its density apparent, focusing on fenced (grazed) and unfenced (ungrazed) areas in a dry forest of southern Ecuador. Focused on a representative species Handroanthus chrysanthus, which contributes to the formation of fertility islands. The methodology included the collection of 10 samples for each zone at two levels of distance 1 and 3 m under the canopy arboreal. The calcination method was used to determine the carbon stock, while that to measure the pH, the soil-water ratio of 1:2.5 was applied with a potentiometer, in change for apparent density, the weight/volume correlation was used. They were obtained significant differences in pH and carbon stock between fenced and unfenced areas fence, in the case of apparent density it did not show relevant changes. Keep the vegetation cover, through the use of fencing is an effective strategy to prevent the loss of nutrients and soil degradation, helping to reduce stress on plants.
