“…El valor 11 de RMSE fue inferior a los obtenidos en los estudios de González et al (2010) y González Molina et al (2011, donde se presentó información del desempeño del RothC en sistemas agrícolas de México; en el primero, los sistemas evaluados se agruparon en sistemas con y sin entrada de RV, y en el segundo, los sistemas se evaluaron en condiciones de ladera, con valor de RMSE de18. En otras partes del mundo y en sistemas agrícolas, forestales y praderas, el RothC se ha usado para predecir los cambios del COS (Coleman et al, 1997;Falloon et al, 1998;Falloon & Smith, 2002).…”

“…González et al (2010) encontraron diferencias significativas entre COS medido y simulado, en razón principalmente de la variabilidad espacial reportada; sin embargo, en el presente estudio, las simulaciones con el RothC mostraron las tendencias de los cambios del COS con un valor de R 2 de 0,76 y una EF del modelo de 0,6. Según el IPCC (2003), es más válido indicar las tendencias del COS en el tiempo do que reportar valores absolutos de los cambios de COS, a pesar de que la incertidumbre reportada en los métodos usados en el primer caso sea mayor.…”

“…Soil organic carbon originates primarily from plants, thus vegetation and land use history is one of the most important driving factors of SOC (Jafarian and Kavian, 2013; González et al, 2010;Strickland et al, 2010). Accurate and reliable estimates of SOC storage in landscapes and land use are critical to the development of effective policies and strategies to mitigate atmospheric and climate change (Sylvia et al, 2016;Lufafa et al, 2008;Zhao et al, 2010).…”

Organic carbon is an important component of soil that influences soil fertility, biological activity, food security, and climate change. One of the important issues in soil science is the establishment of empirical relationships between different soil properties. The objectives of this research were to investigate the influence of different factors on soil organic carbon, such as total nitrogen, clay content, calcium carbonate equivalent and pH, for soils from various geomorphologic settings in the Damavand Region in Northwest Tehran, Iran. Regression models were developed for prediction of the organic carbon content of soils characteristics in this region. Lower SOC concentrations were measured for plateau soils (~4.92 g kg -1 ), associated with lower plant biomass and reduced temperatures at higher elevations. In contrast, soils from River Alluvial Plain regions, which are currently utilized for gardening, had the highest organic carbon content (~22.05 g kg -1 ). For all landform types (i.e., alluvial fan (irrigated farming lands), plateau (Rangeland), and River Alluvial Plain soils (garden)), SOC had positive and significant relationship with total nitrogen (r = 0.962, p < 0.01). Simple linear regression, multiple linear regression, and nonlinear regression models were also developed for describing the relationship between SOC and landforms physical and chemical characteristics.

“…Since our focus was to evaluate the SOC difference between native forests and pasturelands, we carefully ensured that the corresponding data were part of the same research and were conducted simultaneously for each of the observations. Out of 66 paired observations, we found 11 observations for dry tropical forests [29][30][31][32][33][34][35], 13 observations for humid tropical forests [34,[36][37][38][39][40][41][42], 18 for highland forests [34,36,[43][44][45][46][47][48][49], 11 for tropical scrubs and rangelands [34,50,51], and 13 for tropical mangrove forests [34,52]. Inland mangrove forests were converted to pasturelands, especially in southeastern Mexico during the past decades [52][53][54].…”

Soil Organic Carbon Depletion from Forests to Grasslands Conversion in Mexico: A Review

et al. 2018

Land use change from forests to grazing lands is one of the important sources of greenhouse gas emissions in many parts of the tropics. The objective of this study was to analyze the extent of soil organic carbon (SOC) loss from the conversion of native forests to pasturelands in Mexico. We analyzed 66 sets of published research data with simultaneous measurements of soil organic carbon stocks between native forests and pasturelands in Mexico. We used a generalized linear mixed effect model to evaluate the effect of land use change (forest versus pasture), soil depth, and original native forest types. The model showed that there was a significant reduction in SOC stocks due to the conversion of native forests to pasturelands. The median loss of SOC ranged from 31.6% to 52.0% depending upon the soil depth. The highest loss was observed in tropical mangrove forests followed by highland tropical forests and humid tropical forests. Higher loss was detected in upper soil horizon (0–30 cm) compared to deeper horizons. The emissions of CO2 from SOC loss ranged from 46.7 to 165.5 Mg CO2 eq. ha−1 depending upon the type of original native forests. In this paper, we also discuss the effect that agroforestry practices such as silvopastoral arrangements and other management practices like rotational grazing, soil erosion control, and soil nutrient management can have in enhancing SOC stocks in tropical grasslands. The results on the degree of carbon loss can have strong implications in adopting appropriate management decisions that recover or retain carbon stocks in biomass and soils of tropical livestock production systems.
