C_input_crops_LUT {SoilManageR} | R Documentation |
Look-up-table with default values to calculate carbon (C) inputs by crops
Description
The data set is a look-up-table that is used to calculate the C inputs by crops with the Bolinder formula, that is implemented in the function 'SoilManageR::C_input_crops()'. The data set is produced from the excel table 'C_input_crops_LUT.xlsx' file under '/inst/extdata/'.
Usage
C_input_crops_LUT
Format
A tibble with 28 rows and 19 columns:
- Crop
Name of the crop
- RP
Ratio of the C in the product to the total carbon that is allocated by the plant (in a year)
- RS
Ratio of the C in the above ground residues (e.g. straw) to the total carbon that is allocated by the plant (in a year)
- RR
Ratio of the C in the plant roots to the total carbon that is allocated by the plant (in a year)
- RE
Ratio of the C in the root exudates to the total carbon that is allocated by the plant (in a year)
- SP
Proportion of the C in the Product that is transfered to the soil
- SS
Proportion of the C in the above ground residues (e.g. straw) that is transfered to the soil
- SR
Proportion of the C in the roots that is transfered to the soil
- SE
Proportion of the C in root exudates that is transfered to the soil
- crop_product
Reference yield, derived from the Swiss fertilizer recommendations (GRUD, 2017, Chapters 8 and 9) [tDM/ha]
- harvest_index
Ratio of the product to the total of the product and the above ground residues. Calculated by RP/(RP+RS) (assuming all biomass has 45% C)
- varible_harvest_index
Logical value, if the variable harvest index assumption of Fan et al. (2017) are to be aplied or not.
- HI_intercept
Intercept of the variable harvest index assumption of Fan et al. (2017) are to be aplied.
- HI_slope
Slope of the variable harvest index assumption of Fan et al. (2017) are to be aplied. [ha/tDM]
- shoot_root_ratio
Ratio of the product and the above ground residues to the root biomass. Calculated by (RP+RS)/RR (assuming all biomass has 45% C)
- root_exudation_factor
Ratio of the root exudates to the root biomass. Calculated by RE/RR (assuming all biomass has 45% C)
- fixed_belowground_input
Logical value if the fixed below ground C allocation assumption of Taghizadeh-Toosi et al. (2020) is to be applied or not.
- C_input_root
Fixed value of root carbon input that is to be assumed. [kgC/ha]
- Source
Source where the information was derived.
