Forecast hydroponic marketable yield from plant count, expected yield per plant, nutrient-program response, and crop loss. The calculator shows gross output, saleable output, and the modeled difference from an unchanged nutrient program.
Marketable yield = Plants × Baseline kg/plant × (1 + Program response) × (1 − Loss rate)
The main result is expected marketable crop weight after both the nutrient-response assumption and crop loss are applied.
Avoid attributing yield changes solely to nutrition when light, temperature, plant density, cultivar, or harvest timing also changed.
2,000 plants × 0.45 kg × 1.07 × 0.96 = 924.48 kg marketable yield, 60.48 kg above the unchanged-program baseline.
Yes. Enter a negative percentage above -100% to model a poorer result.
No. It only applies the response assumption you enter.
Use the number expected to reach harvest; otherwise loss may be counted twice.
No. Gross yield is shown before the entered unmarketable loss rate.
Use comparable trial data, crop records, or a clearly labeled scenario range.
| Item | Meaning |
|---|---|
| Harvested plants | Plants expected to reach harvest |
| Baseline yield | Crop weight per harvested plant before response and loss |
| Program response | Relative yield change attributed to the nutrient plan |
| Marketable yield | Forecast remaining after unmarketable loss |
