Percentage increase in fresh alfalfa biomass due to the application of various soil amendments compared to control treatments (100% and 60% ETc).
| Control‐60% ETc | 16.32 tons/ha | Control‐100% ETc | 20 tons/ha |
| Soil amendments | 5 tons/ha | 7.5 tons/ha | 10 tons/ha | | % increase of fresh biomass over control treatment with irrigation (ETc 60%) |
| Commercial compost (60% ETc) | 9.68 | 11.98 | 14.87 | Compost (60% ETc) | 103 | 117.0 | 115.8 | Biochar (60% ETc) | 17.89 | 18.36 | 17.93 | Soil conditioner (60% ETc) | 15.32 | 15.11 | 16.12 |
