Stabilization mechanisms of soil organic matter: Implications for C-saturation of soils
The relationship between soil structure and the ability of soil to stabilize soil organic matter (SOM) is a key element in soil C dynamics that has either been overlooked or treated in a cursoryExpand
Soil macroaggregate turnover and microaggregate formation: a mechanism for C sequestration under no-tillage agriculture
Soil disturbance from tillage is a major cause of organic matter depletion and reduction in the number and stability of soil aggregates when native ecosystems are converted to agriculture. No-tillExpand
GRASSLAND MANAGEMENT AND CONVERSION INTO GRASSLAND: EFFECTS ON SOIL CARBON
Grasslands are heavily relied upon for food and forage production. A key component for sustaining production in grassland ecosystems is the maintenance of soil organic matter (SOM), which can beExpand
Aggregation and soil organic matter accumulation in cultivated and native grassland soils
Tillage intensity affects soil structure and the loss of soil organic C and N. We hypothesized that no-tillage (NT) and conventional tillage (CT) differentially affect three physically definedExpand
Soil structure and organic matter: I. Distribution of aggregate-size classes and aggregate-associated carbon.
Cultivation reduces soil C content and changes the distribution and stability of soil aggregates. We investigated the effect of cultivation intensity on aggregate distribution and aggregate C inExpand
Aggregate and Soil Organic Matter Dynamics under Conventional and No-Tillage Systems
Tillage generally reduces aggregation and particulate organic matter (POM) content. We hypothesized that reduced C sequestration in conventional tillage (CT) compared with no-tillage (NT) is relatedExpand
The potential to mitigate global warming with no‐tillage management is only realized when practised in the long term
No-tillage (NT) management has been promoted as a practice capable of offsetting greenhouse gas (GHG) emissions because of its ability to sequester carbon in soils. However, true mitigation is onlyExpand
Management options for reducing CO2 emissions from agricultural soils
Crop-based agriculture occupies 1.7 billion hectares, globally, with a soil C stock of about 170 Pg. Of the past anthropogenic CO2 additions to the atmosphere, about 50 Pg C came from the loss ofExpand
