Other claims from this paper (10)
- Intervention effect Biosolids increased sorghum biomass up to 14.0 t ha −1 eq.
- Intervention effect Biosolids increased rapeseed biomass up to 11.9 t ha −1 eq.
- Intervention effect Biosolids increased ryegrass biomass up to 4.1 t ha −1 eq.
- Intervention effect Biosolids mixed with sawdust produced rapeseed growth similar to biosolids alone.
- Intervention effect Adding sawdust nullified the sorghum growth benefit of biosolids.
- Observation Rapeseed seed yield after biosolids application was 2.5 t ha −1.
- Intervention effect Biosolids and biosolids–sawdust raised plant elemental concentrations, especially Zn.
- Observation Plant Cd, Cr and Ni under biosolids amendments stayed below food safety standards.
- Observation A 50 t ha −1 biosolids application did not exceed soil limits for Cu, Zn and Cd.
- Observation Mixing sawdust with biosolids can further enhance nutrient quality of biomass and seeds, especially P, Cu, Zn, Mn, Fe, S and Na.
