Verify carbohydrate lost #56

Closed lpmorenoc closed 2 years ago

lpmorenoc commented 2 years ago

Based on a comment from James:

When senescence begins, an abscission layer forms at the base of the petiole, and the leaves begin mobilizing carbohydrates and nitrogen to the carbohydrates and nitrogen pools…………. The model assumes 70% of the carbohydrates go to the reserves from the leaves that are senescing. Carbs no! This must be removed.

I can remove the LWLOS species coefficient or define it as 100% lost for nutrient recycling
