Soil organic matter content bins.

Source: R/datasets_balances.R
som_ranges.Rd

Half-open bins that map a soil organic matter share (fraction) to a soil organic matter class. A share s is assigned to the class whose interval satisfies s_min < s <= s_max; the top (High) bin has no finite ceiling in the source and is treated as open-ended (any share above its s_min is "High"), so s_max = 1 here is a wide ceiling, not a literal source value. The classes key the Meisinger denitrification matrix (meisinger_denitrification).

Usage

som_ranges

Format

A tibble with columns:

som_content

Soil organic matter class: "High", "Medium" or "Low".

som_min

Lower bound of the soil organic matter share interval (fraction).

som_max

Upper bound of the soil organic matter share interval (fraction); the "High" row's value is a wide ceiling, not a literal source bound (see Description).
