“…On average, it contains less harmful elements, and could even act as a fertilizer by providing elements that are in deficit in many tropical areas [10]. Basalt has a lower weathering efficiency, which could be partly compensated by increased plant biomass carbon, driven by nutrient release [11,12].…”

The chemical weathering of rocks currently absorbs about 1.1 Gt CO 2 a −1 being mainly stored as bicarbonate in the ocean. An enhancement of this slow natural process could remove substantial amounts of CO 2 from the atmosphere, aiming to offset some unavoidable anthropogenic emissions in order to comply with the Paris Agreement, while at the same time it may decrease ocean acidification. We provide the first comprehensive assessment of economic costs, energy requirements, technical parameterization, and global and regional carbon removal potential. The crucial parameters defining this potential are the grain size and weathering rates. The main uncertainties about the potential relate to weathering rates and rock mass that can be integrated into the soil. The discussed results do not specifically address the enhancement of weathering through microbial processes, feedback of geogenic nutrient release, and bioturbation. We do not only assess dunite rock, predominantly bearing olivine (in the form of forsterite) as the mineral that has been previously proposed to be best suited for carbon removal, but focus also on basaltic rock to minimize potential negative side effects. Our results show that enhanced weathering is an option for carbon dioxide removal that could be competitive already at 60 US $ t −1 CO 2 removed for dunite, but only at 200 US $ t −1 CO 2 removed for basalt. The potential carbon removal on cropland areas could be as large as 95 Gt CO 2 a −1 for dunite and 4.9 Gt CO 2 a −1 for basalt. The best suited locations are warm and humid areas, particularly in India, Brazil, South-East Asia and China, where almost 75% of the global potential can be realized. This work presents a techno-economic assessment framework, which also allows for the incorporation of further processes.

“…Studies have confirmed correlations between parent material and soil texture, pH, porosity, and moisture content [1,2], but also nutrient cycling [3] and fertility [4]. Thus, these characteristics are able to select the aboveground vegetation [5,6] and the soil biological features [7] even in environments that are extreme for climatic or geochemical reasons.…”

Physical and chemical soil properties are generally correlated with the parent material, as its composition may influence the pedogenetic processes, the content of nutrients, and the element biocycling. This research studied the chemical and biochemical properties of the A horizon from soils developed on different rocks like amphibolite, serpentinite, phyllite, and granite under a relatively similar climatic regime from Galicia (northwest Spain). In particular, the effect of the parent material on soil evolution, organic carbon sequestration, and the hormone-like activity of humic and fulvic acids were tested. Results indicated that all the soils were scarcely fertile because of low concentrations of available P, exchangeable Ca (except for the soils on serpentinite and phyllite), and exchangeable K, but sequestered relevant quantities of organic carbon. The scarce soil fertility was common to all soils independently of the parent material, and we attributed this similarity to the pedogenetic pressure induced by the climatic conditions. Also, the hormone-like activity of humic and fulvic acids, similar for all the soils, was probably due to pedogenesis. We hypothesized that the hormone-like activity of the humic substances helps growth and diffusion of vegetation in low fertile soils and, consequently, soil organic carbon sequestration too.

“…Los niveles de P han mantenido un comportamiento de disminución a través de los años, posiblemente por el porcentaje de materia orgánica pero, sin embargo, sigue con un efecto positivo que da continuidad al proceso de sucesión (Ramírez, 1994). Estas variaciones de las condiciones químicas se sustentan en el tiempo por la disponibilidad y reserva de nutrientes que ha generado la disposición de los lodos fluviovolcánicos, a través de largos procesos de intemperización que generan oferta de nutrientes suficientes para satisfacer las necesidades ecológicas de restauración y producción (Anda, 2015).…”

ResumenLos cambios en la calidad de los suelos son determinados por su composición física y química y se relacionan directamente con el desarrollo, el crecimiento y los cambios en la dinámica de los procesos de sucesión vegetal. El objetivo de este estudio fue evaluar la composición física y química del suelo y su relación con la vegetación proveniente de procesos de sucesión ocurridos sobre los lodos fluviovolcánicos del municipio de Armero, Tolima, Colombia. Se establecieron 10 parcelas de 10 x 20 metros y en cada unidad de muestreo se dio apertura a tres calicatas para la obtención de una muestra compuesta. En cada muestra de suelo se determinaron los parámetros físicos y químicos y se estableció la relación entre las variables edáficas mediante un análisis multivariado de componentes principales. Las variables físicas, las densidades real y aparente, el porcentaje de porosidad y de humedad y las variables químicas: pH, fósforo (P), manganeso (Mn), cinc (Zn), calcio (Ca), la saturación de bases: magnesio (Mg), hierro (Fe), cobre (Cu), la relación de magnesio y potasio (relación Mg/K), la relación de calcio más magnesio con potasio ((Ca+Mg)/K), y la saturación y concentración de aluminio (Al), presentaron alta variabilidad y valores sustentables para el desarrollo de la vegetación en la zona de Armero debido a los procesos ecológicos de sucesión. © 2017.

Physical and chemical composition of fluviovolcanic soils in Armero, Tolima, Colombia AbstractChanges in soil quality are determined by their physical and chemical composition and are directly related to the development, growth and changes in the dynamics of plant succession processes. The objective of this study was to evaluate the physical and chemical composition of the soil and its relationship with vegetation from successional processes developed on fluviovolcanic sludge in the municipality of Armero, Tolima, Colombia. Ten plots of 10x20 m were established and three trial pits were opened in each unit to obtain a composite sample. We determined physical and chemical parameters in each soil sample and we established the relationship between the edaphic variables through a multivariate analysis of principal components. Physical variables, actual and apparent density, porosity and humidity percentages and chemical variables: pH, P, Mn, Zn, Ca, base saturation: Mg, Fe, Cu, Mg/K ratio, (Ca+ Mg)/K ratio, and Al saturation and concentration presented high variability and sustainable values for the development of vegetation in Armero as a result of sequential ecological processes. © 2017.
