Fertilizer Calculator

+ +
+
+ +
General Inputs
+ + +
+
+ + (e.g., 50) +
+ +
+ The target yield (Y) is your desired crop yield in kg/ha (or another standard unit). +
+
+ Please enter a realistic yield > 0 (e.g., 10 to 200). +
+
+ + +
Nitrogen (N) Parameters
+ +
+
+ + (e.g., 2) +
+ +
+ NRN represents how much nitrogen is typically required per unit of yield. Ranges often fall between 0.5 – 3.0 depending on the crop. +
+
+ Please enter a realistic value > 0 (e.g., between 0.1 and 5). +
+
+ +
+
+ + (0 <= EfN <= 1) +
+ +
+ EfN indicates the efficiency of nitrogen uptake, influenced by soil conditions, climate, etc. +
+
+ N Efficiency Factor must be between 0 and 1 (e.g., 0.3, 0.45, 0.8). +
+
+ +
+
+ + (0 <= EsN <= 1) +
+ +
+ EsN is how much your soil naturally contributes to nitrogen availability (e.g., 0.2). +
+
+ Soil Contribution Factor must be between 0 and 1. +
+
+ +
+
+ + (e.g., 20) +
+ +
+ SNN is your nitrogen soil test result (e.g., 15 – 40). It helps determine how much N is already available. +
+
+ Please enter a realistic soil test value ≥ 0. +
+
+ + +
Phosphorus (P) Parameters
+ +
+
+ + (e.g., 0.6) +
+ +
+ NRP is the phosphorus ratio per yield unit, typically ranges from 0.1 – 1.0 depending on crop demands. +
+
+ Please enter a realistic value > 0 (e.g., 0.1 to 2). +
+
+ +
+
+ + (0 <= EfP <= 1) +
+ +
+ EfP indicates how effectively phosphorus is taken up by crops under your conditions. +
+
+ P Efficiency Factor must be between 0 and 1. +
+
+ +
+
+ + (0 <= EsP <= 1) +
+ +
+ EsP is how much phosphorus your soil can naturally supply. +
+
+ Soil Contribution Factor must be between 0 and 1. +
+
+ +
+
+ + (e.g., 15) +
+ +
+ SNP is your soil test reading for phosphorus (e.g., 5 – 30), guiding how much P is already present. +
+
+ Please enter a realistic soil test value ≥ 0. +
+
+ + +
Potassium (K) Parameters
+ +
+
+ + (e.g., 1) +
+ +
+ NRK is the potassium ratio per yield unit, which could be from 0.3 – 2.0 for many crops. +
+
+ Please enter a realistic value > 0 (e.g., 0.3 to 5). +
+
+ +
+
+ + (0 <= EfK <= 1) +
+ +
+ EfK indicates how efficiently potassium is used by your crops under local conditions. +
+
+ K Efficiency Factor must be between 0 and 1. +
+
+ +
+
+ + (0 <= EsK <= 1) +
+ +
+ EsK is the natural potassium supply capacity of your soil. +
+
+ Soil Contribution Factor must be between 0 and 1. +
+
+ +
+
+ + (e.g., 40) +
+ +
+ SNK is your soil test reading for potassium (e.g., 30 – 100). +
+
+ Please enter a realistic soil test value ≥ 0. +
+
+ +
