Soil organic matter (SOM) anchors global terrestrial productivity and food and fiber supply. SOM retains water and soil nutrients and stores more global carbon than do plants and the atmosphere combined. SOM is also decomposed by microbes, returning CO2, a greenhouse gas, to the atmosphere. Unfortunately, soil carbon stocks have been widely lost or degraded through land use changes and unsustainable forest and agricultural practices. To understand its structure and function and to maintain and…

Biotic versus Abiotic Controls on Bioavailable Soil Organic Carbon

Processes controlling microbial access to soil organic matter are critical for soil nutrient cycling and C stabilization. The bioavailability of soil organic matter partly depends on the rate that

Grassland soil carbon sequestration: Current understanding, challenges, and solutions.

Grasslands store approximately one third of the global terrestrial carbon stocks and can act as an important soil carbon sink. Recent studies show that plant diversity increases soil organic carbon

Soil carbon stocks in temperate grasslands differ strongly across sites but are insensitive to decade‐long fertilization

It is shown that site factors such as moisture index, plant productivity, soil texture, and mineralogy were key predictors of cross-site soil C, while nutrient amendment had weaker and site-specific effects on C sequestration, which suggests that prioritizing the protection of highly productive temperate grasslands is critical for reducing future greenhouse gas losses arising from land use change.

Soil carbon sequestration accelerated by restoration of grassland biodiversity

It is found that restoration of late-successional grassland plant diversity leads to accelerating annual carbon storage rates that are 200% greater in the authors' highest diversity treatment than during succession at this site, and 70% greater than in monocultures.

Climate and litter C/N ratio constrain soil organic carbon accumulation.

It is concluded that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation.

Can switchgrass increase carbon accrual in marginal soils? The importance of site selection

Most soil carbon (C) is in the form of soil organic matter (SOM), the composition of which is controlled by the plant–microbe–soil continuum. The extent to which plant and microbial inputs contribute

Effects of plant diversity on soil carbon in diverse ecosystems: a global meta‐analysis

The importance of plant diversity preservation for the maintenance of soil carbon sequestration in discussions of global climate change policy is highlighted, as both SOC content and stock are on average 5 and 8% higher in species mixtures than in monocultures.



Litter and Root Manipulations Provide Insights into Soil Organic Matter Dynamics and Stability

Understanding controls on C stored in soil organic matter (SOM) is of critical importance to models of biospheric C sequestration. Although ecosystem C models assume a strong relationship between

Grassland management impacts on soil carbon stocks: a new synthesis.

A new synthesis that has integrated data from hundreds of studies to document soil carbon responses to changes in management confirms that improving grassland management practices and conversion from cropland to grassland improve soil carbon stocks.

Soil carbon storage controlled by interactions between geochemistry and climate

Rising temperature can increase soil organic matter decomposition and CO2 emissions. In a 4,000 km north–south transect in Chile and Antarctica, soil geochemistry, which can be modified by climate,

Breeding crop plants with deep roots: their role in sustainable carbon, nutrient and water sequestration.

Calculations suggest that breeding crop plants with deeper and bushy root ecosystems could simultaneously improve both the soil structure and its steady-state carbon, water and nutrient retention, as well as sustainable plant yields.

Roots and fungi accelerate carbon and nitrogen cycling in forests exposed to elevated CO2.

A common finding in multiple CO(2) enrichment experiments in forests is the lack of soil carbon (C) accumulation owing to microbial priming of 'old' soil organic matter (SOM). However, soil C losses

A global meta-analysis of soil exchangeable cations, pH, carbon, and nitrogen with afforestation.

It is suggested that proper site preparation and sustainable harvest practices, such as avoiding the removal or burning of harvest residue, could minimize the impact of afforestation on soils, and slow soil compaction, erosion, and organic matter loss, maintaining soil fertility to the greatest extent possible.

Mineral control of soil organic carbon storage and turnover

A large source of uncertainty in present understanding of the global carbon cycle is the distribution and dynamics of the soil organic carbon reservoir. Most of the organic carbon in soils is

The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon sequestration with

Evidence for Carbon Saturation in a Highly Structured and Organic-Matter-Rich Soil

Recent studies suggest that mineral soils of temperate ecosystems have a limit in C sequestration capacity, and we reasoned that C saturation will be most evident in soils that are already rich in
