Identifying the carbon isotopic ratio is valuable for analyzing and understanding soil classification and dynamics. This study evaluated and related the soil isotopic ratio and its main properties (physicochemical) in the Monzón Valley. Fifteen pits were sampled within the strata of a toposequence. δ13C was determined using an isotope ratio mass spectrometry system coupled with...
Studies on nutrient absorption patterns allow for the identification of periods of peak nutritional demand, the amount of nutrients accumulated in each organ, the quantity exported by harvest, and the necessary replenishment to the soil. These insights are crucial for developing effective fertilization programs for crops. This study aimed to determine the nutrient absorption...
Tree diversity plays a key role in mitigating climate change and enhancing ecosystem resilience. This study evaluated the contribution of trees across three habitats within the urban-rural gradient of Sucre, Bolivia: urban (UF), native (NF), and exotic (EF). Carbon sequestration, as well as taxonomic (TD), phylogenetic (PD), and functional (FD) diversity, were analyzed in...
Land-use change in the Central Andes of Peru has led to the widespread conversion of tropical montane forests, significantly reducing their carbon storage capacity. This study estimated aboveground and soil carbon stocks across a disturbance gradient: croplands (C), agroforestry systems (AF), regenerating montane forests (BMR), and conserved montane forests (BMC). Using...
