The total quantity of plant or soil N that is derived from fertilizer. Formula: TNdfF = (NdfF/100) * (PlantN or SoilN)
TNdfF(NdfF, PlantN = NULL, SoilN = NULL)
A numeric vector of TNdfF values.
N derived from Fertilizer expressed as a percentage (0-100).
Optional numeric vector for plant N content.
Optional numeric vector for soil N content.
NdfF <- c(15, 20) PlantN <- c(3.0, 3.5) # Case 1: Using Plant N TNdfF(NdfF, PlantN = PlantN) # Case 2: Using Soil N (must specify SoilN explicitly) SoilN <- c(100, 120) TNdfF(NdfF, SoilN = SoilN)
