Drainage-class bins keyed on annual soil drainage.

Half-open bins that map an annual soil drainage flux (mm) to a drainage class. A drainage value s is assigned to the class whose interval satisfies s_min < s <= s_max. The classes key the Meisinger denitrification matrix and the subsoil NO3 reduction table.

Usage

drainage_ranges

Format

A tibble with columns:

drainage_rate

Drainage class: "Very_high", "High", "Medium", "Low", "Very_low" or "None".

s_min

Lower bound of the drainage flux interval (mm).

s_max

Upper bound of the drainage flux interval (mm).
