Summarize BNF Results by Crop or Region

Produces a concise summary of BNF components and environmental adjustment factors from the output of calc_bnf or its component functions. Useful for diagnostics, parameter sensitivity analysis, and reporting.

Usage

summarize_bnf(x, group_by = "Name_biomass")

Arguments

x

Data frame output from calc_bnf() or similar, containing BNF result columns.

group_by

Character vector of columns to group by. Default c("Name_biomass"). Set to NULL for overall summary.

Value

A tibble with per-group summaries:

n

Number of observations.

Cat_leg

Legume category from Pure_legs: "Grain", "Fodder_pure", or NA for non-legume/mixed systems.

total_CropBNF_MgN

Sum of symbiotic crop BNF.

total_WeedsBNF_MgN

Sum of weed/CC BNF.

total_NSBNF_MgN

Sum of non-symbiotic BNF.

total_BNF_MgN

Sum of total BNF.

mean_Ndfa_adj

Mean adjusted Ndfa.

mean_f_env_symb

Mean symbiotic env factor.

mean_f_env_ns

Mean non-symbiotic env factor.

pct_CropBNF

Percent of total from crop.

pct_WeedsBNF

Percent of total from weeds.

pct_NSBNF

Percent of total from NSBNF.

Examples

if (FALSE) { # \dontrun{
load_general_data()
bnf_results <- npp_data |> calc_bnf()
summarize_bnf(bnf_results)
summarize_bnf(bnf_results, group_by = c("Region", "Year"))
} # }
