Formula Citations
| Formula / Method | Reference |
|---|---|
| Target YAN (mg/L) = initial Brix x nitrogen-demand factor x risk factor | WinemakerOS staged nutrient planning model |
| DAP g/L = nitrogen share / (1000 x 0.21); Fermaid-O g/L = share / (1000 x 0.12) | Nutrient nitrogen content conversion |
| Additions complete by 1/3 sugar depletion in the standard staged schedule | Common staggered nutrient addition practice |
