Efecto del uso del suelo sobre los stocks de C y N edáfico en bosque seco

Abstract

Abstract:Anthropogenic activities and forest management practices can negatively and irreversibly modify soil characteristics. The objective of the research was to quantify the changes in soil C and N reserves under different edaphic uses and to evaluate the effect of soil use on edaphic nutrients. The study was carried out in dry forest in southern Ecuador, where the carbon and nitrogen stocks and the nutrient contents in the soil were estimated in three uses, the excluded zone, the non-excluded zone and the cultivation zone. The results show that the change in use has a significant impact on the carbon and nitrogen stocks of the soil. The excluded area presented higher values in all the nutrients studied compared to the non-excluded area, but it was not the same trend compared to the crop area, the practices used probably influenced the results. Forest conservation should be promoted and for disturbed areas such as crops, the implementation of management practices that capture carbon and nitrogen from the soil should be encouraged to mitigate global warming.
