“…In addition, the results obtained for the three depths in the studied scenarios demonstrated that the data mining techniques enabled the development of an efficient model for the classification of C stock in ABE by using feature selection methods and the J48 algorithm for the decision tree induction. The results of data mining in ABE were consistent with the literature (Farhate et al., 2018; Lima et al., 2017), indicating that data mining techniques are applicable in soil science.…”

“…For this study, the soil sampling was conducted in rural areas in the southern region of the state of Amazonas, in areas with five different land uses and the presence of an anthropogenic A horizon, according to Santos et al (2018). The forest and pasture areas are located in the municipality of Novo Aripuanã (07 • 51′30″ S; 61 • 18′01″ W), and the coffee, cacao, and bean cultivation areas are situated in the municipality of Apuí (07 • 12′05″ S; 59 • 39′35″ W) ( Figure 1).…”

In the Amazon, there are soils associated with continued human occupation known as "archeological black earth" (ABE). Due to its physical and chemical properties, ABE is more productive than other typical soils in the same region. Therefore, its carbon (C) sequestration mechanism has been a major topic of discussion by the scientific community, aiming to replicate similar characteristics in other soils. Thus, the objective of this study was to develop a predictive model using feature selection and decision tree induction methods for predicting soil C stock in ABE under different land use scenarios. The experiment was carried out in agricultural (coffee, cacao, and beans), pasture, and forest areas. Four feature selection approaches were used to identify the most relevant variables for the proposed model: (i) correlation-based feature selection, (ii) the χ 2 test, (iii) the Wrapper method, and (iv) no feature selection. The decision tree induction technique available in the Weka software was selected for data classification. Soils under cacao and coffee cultivation tend to accumulate more C when compared with soils located at bean crops, pasture, or forest land use systems. Land use and sand content were among the most important variables for the prediction of soil C stock in ABE. Furthermore, the use of a decision tree was effective at predicting soil C stocks for these soils because it enables the creation of models with high accuracy rates of 83, 74, and 81% (using seven, seven, and four rules at depths of 0.00-0.05, 0.05-0.10, and 0.10-0.20 m, respectively). 1 INTRODUCTION In the Amazon, soils with anthropogenic A horizon are associated with long-term human occupation by pre-Columbian indigenous societies (Santos et al., 2017), which formed extensive deposits of organic residues, significantly

“…Every 10ºC the respiration rate doubles, up to 35-40ºC, from which temperatures are limiting; in turn, it is also limited below 5°C (Li et al, 2018). The respiration rate (TRS) also increases as the volumetric content of water or moisture increases, which is, in turn, a numerical, percentage measure of soil moisture to saturation levels, where this rate begins to decline and begins to produce anaerobiosis with denitrification and volatilization of sulfur (Vieira et al, 2018).…”

ABSTRACT Soil respiration in forest ecosystems is considered to be the second most important carbon flux between the biosphere and the atmosphere. In tropical forests, the factor that most influences soil respiration is the temporal variation in temperature, and in water content or precipitation; the soil temperature is relatively constant. The behavior of the RS was established, and this ecological process was estimated and modeled for a tropical mountain forest in the State of Hidalgo, Mexico. It has contributed to strengthening the theoretical framework for the restoration and ecological conservation of this forest, considered a National Park, this has been the main objective of this work. Its relationship with the climatic parameters and factors that regulate CO2-soil-atmosphere fluxes in an annual cycle was analyzed. The daytime respiratory rate was slightly higher (average of 3.54 tmCO2/ha) than the nocturnal one (average of 3.35 tmCO2/ha), depending on the ambient temperature and the climatic conditions. The humic acid found in the soils was classified for the mountainous wooded area of the Chico National Park. Andosols are humic soils and humic acids were classified predominantly as type A. According to the results obtained, with only one year of evaluation, it should be noted that it is necessary to carry out a greater number of evaluations, at least during a period of 5 to 10 years and for different seasonal periods, in order to strengthen the responses found for this ecosystem.

“…Cada 10ºC se duplica la tasa de respiración, hasta llegar a los 35-40ºC, a partir de los cuales las temperaturas son limitantes; a su vez también queda limitada por debajo de 5°C (Li et al, 2018). La tasa de respiración (TRS) también aumenta conforme aumenta el contenido volumétrico de agua o humedad, que es a su vez, una medida numérica, porcentual, de la humedad del suelo hasta niveles de saturación, donde esta tasa comienza a declinar y se comienza a producir anaerobiosis con desnitrificación y volatilización de azufre (Vieira et al, 2018).…”

La respiración del suelo (RS) en ecosistemas boscosos se considera como el segundo flujo de carbono más importante entre la biosfera y la atmósfera; cerca de la mitad de la RS se deriva de la actividad metabólica, soporte y crecimiento radicular y asociación con micorrizas. En bosques tropicales, el factor que mayor influencia tiene sobre la variación temporal de la RS, no es tanto la temperatura, sino el contenido de agua o la precipitación debido a que la temperatura del suelo es relativamente constante. El objetivo del trabajo ha sido establecer el comportamiento de la RS y tratar de estimar y modelar el proceso ecológico de la RS en la fase priseral arbustiva de un bosque de montaña en el Estado de Hidalgo, con el fin de fortalecer el marco teórico de la ecología de la restauración y de la biología de la conservación, así como analizar su relación con los parámetros meteorológicos para entender cuáles son los factores que regulan los flujos del CO2 suelo-atmósfera en un ciclo anual. Por los resultados alcanzados, debe señalarse que será necesario realizar un número mayor de evaluaciones en un tiempo de 3 a 5 años y en épocas y períodos estacionales con vistas a reforzar estos resultados. Se pudo concluir tres aspectos importantes, en primer lugar, que la RS es parte del reservorio de carbono en ecosistemas forestales; la RS del suelo es una variable dependiente del tiempo y de la altitud, a mayores tiempos mayores valores de RS y a mayores altitudes también. Se encontró que la tasa de respiración diurna (TRSD) es ligeramente mayor que la nocturna (TRSN), al parecer dependiente de la temperatura ambiente. Se logró clasificar los AH de suelos de la zona boscosa de montaña del Parque Nacional del Chico. Ya se reportaba que eran suelos andisoles húmicos, pero en este trabajo se clasifican como AH de tipo A predominante.
