- Intervention effect Biochar significantly decreased mineral N leaching, including nitrate levels (35%), compared with without biochar.
- Intervention effect Biochar increased electrical conductivity by 68.5% compared with without biochar.
- Intervention effect Biochar increased water availability (20% inches per foot) compared with without biochar.
- Intervention effect Biochar produced a non-significant increase in biomass per plant (2.84%).
- Intervention effect Biochar produced a non-significant increase in evapotranspiration (8.33%).
- Intervention effect Biochar produced a non-significant increase in dry matter (6.89%).
- Intervention effect Biochar produced a non-significant decrease in mean leachate volume (7.63%).
- Intervention effect Biochar treatments accumulated higher N uptake (38%) than without biochar after cropping.
- Intervention effect Biochar treatments accumulated higher water use efficiency (12.24%) than without biochar.
- Intervention effect Biochar treatments accumulated higher maximum fresh weight (11.4%) than without biochar.
- Intervention effect Biochar treatments retained more soil N (185%) after cropping than without biochar.
- Observation Soil pH, bulk density and total nitrogen were changed but the differences were non-significant.
