t0“Simultaneous enhancement of carbon sequestration and crop productivity through excessive biochar application in root vegetable (Raphanus raphanistrum L.) cultivation”
e0“This study evaluated the impact of a 10-times higher biochar application (20 t ha − 1 ) on root vegetable ( Raphanus raphanistrum L.) cultivation and soil carbon sequestration, focusing on two methods broadcasting (O-BC) and band application (B-BC)”
e1“The O-BC treatment improved root growth in Raphanus raphanistrum L. by increasing biomass and enhancing the uptake of P and K, thereby boosting productivity and nutrient assimilation”
e2“The O-BC treatment resulted in greater biomass accumulation and enhanced P, K uptake in root tissue, leading to the highest yield (4.67 t ha⁻¹), followed by B-BC (4.51 t ha⁻¹) and the control treatment (4.28 t ha⁻¹)”

Other claims from this paper (8)
- Intervention effect Broadcast biochar (O-BC) gave greater biomass accumulation than the control.
- Intervention effect Broadcast biochar (O-BC) enhanced the uptake of P and K compared with the control.
- Intervention effect Broadcast biochar (O-BC) gave the highest yield of Raphanus raphanistrum, 4.67 t ha⁻¹.
- Intervention effect Band application (B-BC) gave a yield of 4.51 t ha⁻¹, following broadcast biochar and above the control.
- Intervention effect Band application (B-BC) provided only modest benefits to Raphanus raphanistrum.
- Mechanism Localized high concentrations of biochar in band application likely created temporary soil imbalances that limited optimal root development.
- Intervention effect Biochar applied at 20 t/ha enhanced soil carbon sequestration to 43.75 t ha⁻¹, 10 times the conventional amount.
- Recommendation A high amount of biochar applied with the optimal method can overcome high-rate risks and improve root vegetable productivity.
