- Intervention effect Addition of 50 and 100 mg kg−1 HA significantly increased shoot dry weight of maize by 20 and 23% relative to control.
- Intervention effect Addition of 50 and 100 mg kg−1 HA significantly increased root dry weight of maize by 39 and 32% relative to control.
- Intervention effect HA above 50 and 100 mg kg−1 had no significant effect on maize yield.
- Intervention effect HA treatments improved soil organic matter content slightly, by 7 to 14%.
- Intervention effect HA treatments decreased soil pH by 0.2 to 0.3 unit.
- Intervention effect Addition of HA significantly increased soil N concentration and plant N accumulation over control.
- Intervention effect Different levels of HA applied showed no significant differences in soil N concentration and plant N accumulation.
- Intervention effect Addition of 200 mg kg−1 HA significantly improved soil P concentration.
- Intervention effect Plant P accumulation of maize was not significantly affected by different levels of HA.
- Intervention effect Application of HA nonsignificantly increased soil micronutrient concentrations and their accumulation by maize.
- Intervention effect Addition of 0.5 and 1.0 kg ha−1 HA promoted soil CO2 evolution in a laboratory incubation.
- Intervention effect Addition of 0.5 and 1.0 kg ha−1 HA increased soil bacterial population by 355% to 476%.
- Intervention effect Addition of 0.5 and 1.0 kg ha−1 HA increased cation exchange capacity of the soil by 13.8 to 28.9%.
- Association Increased growth of maize due to HA addition may be associated with the improved biochemical environment of the soil.
