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, ...
متن کاملInfluence of Anionic Surfactant on Saturated Hydraulic Conductivity of Loamy Sand and Sandy Loam Soils
Surfactants released into the terrestrial environment in large amounts can potentially alter the physical, chemical and biological properties of soils, particularly the saturated hydraulic conductivity (Ks). Unfortunately findings regarding this process are quite limited. In this study, column tests were used to analyze the effects of Aerosol 22, a widely used anionic surfactant, on Ks of loamy...
متن کاملGlobal carbon sequestration in tidal, saline wetland soils
[1] Wetlands represent the largest component of the terrestrial biological carbon pool and thus play an important role in global carbon cycles. Most global carbon budgets, however, have focused on dry land ecosystems that extend over large areas and have not accounted for the many small, scattered carbon-storing ecosystems such as tidal saline wetlands. We compiled data for 154 sites in mangrov...
متن کاملCarbon sequestration in soils: some cautions amidst optimism
A sink for atmospheric carbon (i.e., CO2) in soils may derive from the application of conservation tillage and the regrowth of native vegetation on abandoned agricultural land. Accumulations of soil organic matter on these lands could offset emissions of CO2 from fossil fuel combustion, in the context of the Kyoto protocol. The rate of accumulation of soil organic matter is often higher on fert...
متن کاملEnhancement of Carbon Sequestration in U . S . Soils
Improved agricultural, forestry, and land management practices could be used to increase soil carbon and thereby significantly reduce atmospheric CO2 concentration. Understanding biological and edaphic processes that increase and retain soil carbon can lead to specific manipulations for enhancement of soil C sequestration. These manipulations, however, will only be suitable for adoption if they...
