STIR_values_LUT {SoilManageR} | R Documentation |
Look-up-table with default values for tillage operations
Description
The dataset is a look-up-table that is used to derive STIR values with the function 'SoilManageR::STIR()' and residue incorperation by tillage operations with the function 'SoilManageR::soil_cover()'. The data set is produced from the excel table 'STIR_value_LUT.xlsx' file under '/inst/extdata/' and was mostly derived from the official RUSLE2 database (USDA-NRCS 2023).
Usage
