FOM Subpools #9169

Open hrpasl opened 3 months ago

hrpasl commented 3 months ago

Describe the new feature

Request for a manager script and any changes to the source code required to: i. Allow for changes to the default fractions (current defaults 0.1 FOMLignin, 0.7 FOMCarbohydrate, 0.2 FOMCellulose) ii. Allow separate CNratio for Lignin, Cellulose, Carbohydrate pools – currently the InitialNitrogen of FOMLignin, FOMCellulose and FOMCarbohydrate are specified as a function of a single [Soil].Organic.FOM.CNRatio iii. Allow changes to decomposition rates of FOMLignin, FOMCellulose, FOMCarbohydrate

This issue elaborates on and hence can be merged with Issue #8979 Ability to test different ratios subpools FOM and their C:N submitted back in May 2024.

The issue is not about just adding different organic materials - we need to be able to reflect their characteristics in the FOM pools once incorporated into the soil. This will form the basis for 1) sensibility tests for nutrient module of different immobilisation-mineralisation patterns, and 2) testing if/when the assumption of a single "mixed" FOM pool holds.
