Measure how efficiently a hydroponic crop converts supplied nutrient mass into marketable harvest. Enter nutrient concentrate used, its active nutrient fraction, harvested crop weight, and crop loss to compare nutrient input with saleable output.
Active nutrient = Concentrate × Active fraction
Feed conversion = Active nutrient ÷ Marketable harvest
The main result reports kilograms of active nutrient supplied for each kilogram of marketable crop.
This is an operational mass-balance ratio, not a universal biological benchmark. Compare like crops, stages, products, and seasons.
80 kg of concentrate at 18% contains 14.4 kg active nutrient. A 5,000 kg harvest with 6% loss leaves 4,700 kg marketable, giving 0.0031 kg nutrient/kg crop.
No. It is an analogous hydroponic input-to-harvest mass ratio.
No. Enter concentrate mass and its active nutrient fraction.
It relates nutrient input to sellable output after crop losses.
Yes, if their active fractions are entered consistently and crop conditions are comparable.
Not necessarily. Underfeeding can lower yield or quality even when the ratio appears efficient.
| Item | Meaning |
|---|---|
| Concentrate used | Total nutrient product consumed during the crop cycle |
| Active fraction | Share of product counted as active nutrient |
| Marketable harvest | Gross harvest after unmarketable loss |
| Feed conversion | Active nutrient divided by marketable crop mass |
