Projects

Understand how plants influence soil pore characteristics and their relationships to soil C gains across contrasting topography

Lead Institution

Michigan State University

Principal Investigator

Alexandra Kravchenko

Project type

Limited Scope

An extra benefit of bioenergy crops is enhanced soil carbon (C) sequestration, which not only reduces atmospheric CO2, but also improves soil fertility, quality, and health. However, the mechanisms…

Assess fate of plant-originated C and N - contribution of switchgrass to soils with contrasting pore size distributions

Lead Institution

Michigan State University

Principal Investigator

Alexandra Kravchenko

Project type

Limited Scope

The CO2 and N2O emissions from agricultural soils are an important component of global greenhouse gas emissions, but are hard to accurately estimate. The primary cause is high spatial and temporal…

Fate of plant-originated C contribution of switchgrass to soils with contrasting pore size distributions

Lead Institution

Project type

BRC Research

This proposal requests analysis of a set of samples from a 13C and switchgrass (Panicum virgatum L.) labeling experiment. The goal of the experiment is to assess the fate of the C assimilated by the…
