N_input {SoilManageR} | R Documentation |
Estimate nitrogen input
Description
This function estimates the nitrogen (N) input by mineral and organic fertilization into the soil system per year.
Usage
N_input(var_MGMT_data, extended.output = FALSE)
Arguments
var_MGMT_data |
a |
extended.output |
an optional logical value:
|
Details
The function takes a management_df
as input and returns N input values
per year in the management_df
.
Alternatively, it can return a extensive tibble with all management operations and their N input values.
The functions calculates the N input by
organic fertilization with the calculate_N_input_tibble()
and the
CN_input_amendments()
function.
Furthermore, it calculates the livestock intensity (LSU/ha
) by deviding
the animal derived N by 105kgN/LSU
.
Be aware that the function currently neglects N that is fixated by plants (e.g. legumes)
Value
by default, a tibble with N input values (organic N, mineral N and total N) by year is returned. If extended.output = TRUE, a tibble with daily resolution is returned.
