Evaluating the impact of increasing temperatures on changes in Soil Organic Carbon stocks: sensitivity analysis and non-standard discrete approximation

  title={Evaluating the impact of increasing temperatures on changes in Soil Organic Carbon stocks: sensitivity analysis and non-standard discrete approximation},
  author={Fasma Diele and Ilenia Luiso and Carmela Marangi and Angela Martiradonna},
A novel model is here introduced for the SOC change index defined as the normalized difference between the actual Soil Organic Carbon and the value assumed at an initial reference year. It is tailored on the RothC carbon model dynamics and assumes as baseline the value of the SOC equilibrium under constant environmental conditions. A sensitivity analysis is performed to evaluate the response of the model to changes of temperature, Net Primary Production (NPP), and land use soil class (forest… Expand


Non-Standard Discrete RothC Models for Soil Carbon Dynamics
The original discrete formulation of the RothC model was compared with a novel non-standard integrator that represents an alternative to the exponential Rosenbrock–Euler approach in the literature. Expand
A proposal for using process-based soil models for land use Life Cycle Impact Assessment: application to Alentejo, Portugal.
Abstract Human occupation and transformation of land are a root cause of ecosystem services degradation. For example, land use (LU) and land use change (LUC) are drivers of soil organic carbon (SOC)Expand
Modification of the RothC model for simulations of soil organic C dynamics in dryland regions
Abstract The Rothamsted Carbon Model (RothC), models the turnover of soil organic carbon (C) in non-waterlogged topsoils. It requires only easily obtainable inputs, and has been widely andExpand
How will organic carbon stocks in mineral soils evolve under future climate? Global projections using RothC for a range of climate change scenarios
Abstract. We use a soil carbon (C) model (RothC), driven by a range of climate models for a range of climate scenarios to examine the impacts of future climate on global soil organic carbon (SOC)Expand
Projected changes in mineral soil carbon of European croplands and grasslands, 1990–2080
We present the most comprehensive pan-European assessment of future changes in cropland and grassland soil organic carbon (SOC) stocks to date, using a dedicated process-based SOC model andExpand
Detailed global modelling of soil organic carbon in cropland, grassland and forest soils
It is found that conversion to cropland can result in SOC increases, particularly when the soil remains covered with crop residues or using irrigation, which are mutually reinforcing effects. Expand
The CENTURY model
The CENTURY model simulates the dynamics of carbon (C), nitrogen (N), phosphorus (P), and sulfur (S) for different plant-soil systems. The model can simulate the dynamics of grassland systems,Expand
RothC-26.3 - A Model for the turnover of carbon in soil
Rothc-26.3 is a model of the turnover of organic carbon in non-waterlogged soils that allows for the effects of soil type, temperature, moisture content and plant cover on the turnover process. ItExpand
The Rothamsted soil-carbon turnover model — discrete to continuous form
Abstract This paper examines the Rothamsted soil-carbon turnover model. This model and other soil carbon turnover models are increasingly being used in climate change and land use studies. TheExpand
Mathematical Analysis of a Nonlinear Model of Soil Carbon Dynamics
MOMOS model (Modelling Organic changes by Micro-Organisms of Soil) is a nonlinear system of ordinary differential equations, which models the dynamics of carbon in soil. This “compartmental” modelExpand
