Carbon Sequestration in Agricultural Soils

Although it is common to alternate between till and no-till practices, past research has considered farmers’ tillage options to be limited to the dichotomous choice of whether or not to switch to a long-term no-till regime. This paper expands farmers’ options and models their choices of tillage frequency. Less frequent tilling sequesters more carbon but permits a greater accumulation of weeds, ...

long term estimation of carbon dynamic and sequestration for iranian agro-ecosystem: ii- sequestration and emission of carbon for common agricultural crops using icbm model

introduction carbon sequestration is one of the most important approaches to reduce co2 concentration in the atmosphere. increase of co2 in the atmosphere has prompted renewed interest in increasing the stocks of carbon (c) in the world’s croplands to mitigate climate change and also improve soil quality ipcc (2000). to better characterize, predict and manage soil c dynamics, more precise and a...

Carbon sequestration by Australian tidal marshes

Australia's tidal marshes have suffered significant losses but their recently recognised importance in CO2 sequestration is creating opportunities for their protection and restoration. We compiled all available data on soil organic carbon (OC) storage in Australia's tidal marshes (323 cores). OC stocks in the surface 1 m averaged 165.41 (SE 6.96) Mg OC ha-1 (range 14-963 Mg OC ha-1). The mean O...
