Other claims from this paper (12)
- Intervention effect Compost with 40% biochar addition reduced N loss from the compost mass compared to the control, to 29.9%.
- Intervention effect Biochar addition caused a more rapid temperature increase during composting.
- Intervention effect Biochar addition truncated the thermophilic phase of composting.
- Intervention effect Finished compost with 40% biochar had greater NO3--N concentration.
- Intervention effect Finished compost with 40% biochar had lower electrical conductivity.
- Intervention effect Finished compost with 40% biochar had greater carbon to nitrogen ratio.
- Intervention effect Finished compost with 40% biochar had greater total carbon content.
- Intervention effect Application of composted biochar at 40% increased potato tuber weight by 40% relative to an unamended control.
- Intervention effect High application rates of compost tended to decrease soil bulk density relative to an unamended control.
- Intervention effect High application rates of compost tended to increase total N in soil relative to an unamended control.
- Intervention effect No differences in soil properties were detected between compost and composted biochar treatments.
- Intervention effect Assuming no N was lost from the added biochar, the difference in N loss was not significant at P = 0.100.
