Description

tasks

• [ ] review proposal and associated literature
• [ ] review existing codebase
• [ ] #11
• [ ] summarize existing code flow (high level)
• [ ] document additions to workflow (where new equations go)
• [ ] testing approach: assure essential functionality, maybe focused at level of compiled model (vs. fn) behavior.

• start with separate litter and bulk SOM (not 3 pools)
• separate NH4 and NO3 pools
• N fixation limited to legumes
