Soils and land use in the study of soil organic carbon in Colombian highlands catena
Fecha de publicación: 01/05/2019

Andean highland ecosystems (known as paramos) have a great potential to store water and organic carbon, which fulfill the inherent functions associated to the regulation of carbon and water cycles, characteristics linked to their parent material (volcanic ash). However, paramos are at high risk of degradation associated with land use dynamics that affect organic carbon quality in the surface soil.
Changes in vegetation cover, with transition from natural forest to tillage and then pasture, make the soil vulnerable to degradation by compaction, erosion, and carbon dioxide emissions associated with increased anthropogenic activity. Despite this cover change, information on soil carbon dynamics in paramos is scarce, impeding conservation management strategies in these ecosystems. This study evaluates the impact of different soil uses within a transect in the Guerrero paramo estimated from soil organic carbon (SOC) stock in the upper meter and carbon condition (expressed as stratification ratio, SR) in the surface soil. Carbon storage varied from 165.2 to 721.9 t ha −1 in the upper meter of soil with SR 1 (0–10/10–20cm) between 0.92 and 2.01 and SR 2 (0–10/20–30cm) between 0.99 and 2.05. Results of this study highlighted that in the fragile ecosystems than Andean paramos, the geomorphological position in relation to soil uses and management practices conditioned soil carbon availability, affecting pedogenetic processes. SR of SOC associated to anthropogenic intervention activities it does not indicate by itself C sequestration. In future researches it is necessary include additional parameters than net primary productivity and historic vegetation

Latin America is considered one of the most diverse regions in relation to natural resources. This area offers 31% of the world’s fresh water, and has approximately 23% of land considered high productive potential. Rapid population growth has increased the demand for ecosystem services offered by soil. This is causing greater anthropogenic intervention, reflected mainly in the conversion of natural ecosystems to agricultural soils, which affects their quality. In recent decades, productive activities have been directed towards sustainability, ratifying the need to guarantee food security at a global level. In this context, agriculture faces the challenge of producing food and raw materials in a sustainable manner, which favors the reduction of pollutant emissions, in order to maintain soil quality and face the threats posed by climate variability and change. In Colombia, a large percentage of agricultural activity takes place in the central zone of the country, where the department of Cundinamarca occupies the seventh place, producing vegetables, fruits, potatoes, flowers, among others. These crops, in many cases, are produced intensively, without considering the impact they can have on the productive capacity of the soil. Hence the importance of the participation of future professionals in the discipline in relation to sustainable production. The purpose of this work was to characterize and evaluate the current state of the soil at free exposure (1218 m2), in the investigative and productive unit El Remanso, which is located at coordinates 4°47’58.93’’N and 74°2’48»W, in the savannah of Bogotá, Cundinamarca, Colombia. For this, we use quality indicators, following the standard USDA methodologies, such as apparent density, real density, porosity, texture, humidity and pH. The results obtained, led to establish that the evaluated soils have influence of volcanic ash, which improves some properties such as moisture retention, accumulation of organic matter, among others. Likewise, they have textures C, SiC, CL SCL, SiCL and SiL, pH between slightly acid and moderately alkaline (6.5-8.2), average bulk density of 0.73 g/cm3. The surface horizon allowed identifying two activities that can influence the loss of soil quality. Otherwise, the loss of structure is associated with conventional tillage practices, a condition that makes compaction probable. On the other hand, the loss of nutrients, structure and humidity is related to intensive production.
