Other claims from this paper (11)
- Intervention effect Adding AOD slag into soil increased soil pH.
- Observation The leaching concentration of Ca, Si and Al from AOD slag was higher than from the original soil.
- Observation The leaching concentration of Cr from AOD slag was higher than from the original soil.
- Observation The leaching concentration of Mg, Mn and Fe from AOD slag was lower than from the original soil.
- Intervention effect Low AOD slag addition (≤1%) was good for plant height, biomass and root growth.
- Intervention effect High AOD slag addition (≥2%) had an opposite effect on plant height, biomass and root growth.
- Intervention effect High AOD slag addition (≥2%) had an opposite effect on chlorophyll synthesis.
- Intervention effect Elevating the AOD slag fertilization rate increased Cr accumulation in tall fescue seedlings.
- Mechanism Cr accumulation aggravated reactive oxygen species damage in tall fescue.
- Mechanism At a low rate (≤1%), ROS scavenging was attributed to synergistic SOD, POD and CAT defence systems.
- Mechanism At a high rate (≥2%), scavenging of excessive ROS was mainly due to the CAT defence system.
