US researchers question published no-till soil organic carbon sequestration rates

2014.05.11 | Agriculture and food

For the past 20 years, researchers have published soil organic carbon sequestration rates. Many of these findings have suggested that soil organic carbon (SOC) can be sequestered in soil, or stored long-term, simply by switching from conventional tillage to no-till systems.

Rewards for sequestering carbon can help improve food security

2014.05.06 | Agriculture and food

The global food supply could be made more secure by actively encouraging smallholder farmers in countries that have an insecure food supply to sequester carbon in the soil by altering their cultivation practices. This can also improve soil quality and reduce greenhouse gas emissions.

    Welcome to SmartSOIL

    SmartSOIL focuses on arable and mixed farming systems in Europe and will develop an innovative approach using the soil C flow and stocks concept to assess the impact of C management on crop productivity, soil organic C (SOC) stocks and other ecosystem services.

    SmartSOIL will develop a decision support tool (DST) to enable farmers, advisors and policy makers to discuss and select the most appropriate and cost-effective practices for particular farming systems, soils and climates - in a smart way (SmartSOIL).

    Linking soil functions to carbon fluxes and stocks

    Changes in soil C contributes to the GHG balance (positively or negatively). Soil C affects soil functioning and thus productivity. These issues are not (fully) incorporated in farm management practices, policies or incentives for agriculture.

    Soil organic matter - Does it matter?

    One of the topics in SmartSOIL is to explore the effects of long-term versus short-term addition of organic matter to the soil. In a long-term experiment, experimental plots have been treated with various inputs of soil organic matter in the form of straw. In the SmartSOIL project, in some plots this practice has been stopped whereas in other plots without straw addition, this has now been added. On top of both types of treatments, different rates of nitrogen is added of short- versus long-term carbon input on crop nitrogen supply and nitrogen use efficiency.
