The primary goal of Subtask 2 is to elucidate the biological, chemical, and physical mechanisms controlling the long-term storage of carbon in agricultural soils.

Task 1, Subtask 3: Greenhouse gas fluxes and dissolved carbon export

Subtask 3 research will include an investigation of carbon exports via leaching in relation to the overall soil carbon budget, and how such exports could be affected by management of soil water status and limestone amendments.

Increasing soil C through changes in land use and management is a low cost and environmentally beneficial method of sequestering substantial amounts of atmospheric CO2.

Integrating Soil Physics, Soil Chemistry and Soil Biology to Understand C Sequestration

As atmospheric levels of CO2 increase steadily, the ability of terrestrial systems to assimilate this burden of CO2 is critically linked to the amount of C sequestered in soils and to the rate that biomass is converted to and sequestered as soil C.

Controls on Soil Organic Matter Dynamics. A Cross Site Comparison

The dynamics of soil organic matter (SOM) is a major factor in soil fertility and determines whether soils sequester or lose carbon under different management practices.

The overall goal of Task 2 is to enter into partnerships to identify, develop, and evaluate agricultural best management practices, including partnerships between (A) federal, State, or private entities; and (B) the Department of Agriculture.

Task 2, Subtask 1: Land management systems

We propose to evaluate system impacts of alternative management practices for C sequestration on other soil quality parameters (e.g. soil N and water holding capacity) and on mitigation of other GHGs at selected sites.

Task 2, Subtask 2: Perennial systems

Established, long-term field study sites will be used to assess an array of management practices on the rate of soil C sequestration in rangelands, native and restored grasslands, forest lands and wetlands. Net primary productivity and biomass-C inputs

Task 2, Subtask 3: Irrigated systems

We propose to develop our knowledge about how BMPs related to irrigation and drainage impact soil C by using a two-tiered approach integrating detailed site-level measurements with regional-level investigations of physical and economic impacts of BMP's.
