# plnt\_decomp

The plant residue decomposition coefficient is the fraction of residue that will decompose in a day assuming optimal moisture, temperature, C:N ratio, and C:P ratio.

{% hint style="info" %}
A default value of 0.05 is used for all plant species in the database, but users may vary decomposition by plant species.
