Carbon Sequestration Rate

Annual rate of soil carbon change between two measurement time points.

carbon_sequestration_rate(soc_initial, soc_final, years, verbose = TRUE)

Arguments

soc_initial

Numeric vector. Initial SOC stock (Mg C/ha).

soc_final

Numeric vector. Final SOC stock (Mg C/ha).

years

Numeric. Number of years between measurements.

verbose

Logical. If TRUE, prints informational messages. Default TRUE.

Value

Numeric vector. Carbon sequestration rate (Mg C/ha/year). Positive values indicate net sequestration; negative values indicate net emission from soil.

Details

Formula: $$CSR = \frac{SOC_{final} - SOC_{initial}}{Years}$$
