Function: calculateDose()
calculateDose(
__namedParameters):Dose
Defined in: fdm-calculator/src/doses/calculate-dose.ts:17
Calculates the cumulative doses of nitrogen, phosphate (as P2O5), and potassium (as K2O) applied to a field as kg / ha
This function iterates over each fertilizer application to determine its contribution to the overall nutrient dose by matching it with a corresponding fertilizer. For each application, it calculates the nutrient dose by multiplying the application amount by the fertilizer's nutrient rate and then sums all doses into a total dose object.
Parameters
__namedParameters
applications
getFertilizerApplicationType[]
fertilizers
getFertilizerType[]
Returns
An object containing the total doses with properties: p_dose_n (nitrogen), p_dose_nw (workable nitrogen - adjusted by the p_n_wc coefficient), p_dose_p2o5 (phosphate as P2O5), and p_dose_k2o (potassium as K2O).
Throws
If any fertilizer application amount or nutrient rate is negative.
