▼a In Chapter 1, I review establishment constraints and variability in production to argue that cover cropping in northern climates requires specific agronomic systems and "buy-in" from farmers and government agencies. |

▼a In Chapter 2, I used a biometric approach to the net ecosystem C balanced (NECB) of maize-cover crop and found that grain maize's NECB hovered near zero, suggesting that with or without cover crops the systems had marginal ability to increase so |

▼a In Chapter 3, I carried out a litterbag experiment on maize residue decomposition, soil or litter microbial decomposer community and analyzed particulate organic matter (POM) and potentially mineralizable C (PMC) as indices of active C. We found |

▼a In Chapter 4, we report on a laboratory incubation evaluating whether temperature and moisture effect on physical protection of decomposing plant litter C. We found that higher temperatures increased C mineralization, shifted bacterial compositi |
