Other claims from this paper (17)
- Association The sludges increased fescuegrass yields for 35 weeks.
- Association Municipal sludge gave higher fescuegrass yields than swine sludge during this period.
- Observation Municipal sludge N recovery in harvested grass was 24% over the first five harvests.
- Observation Swine sludge N recovery in harvested grass was 16% over the first five harvests.
- Association Surface application gave greater N recovery (24%) than incorporation (16%).
- Association Copper concentration in fescuegrass was not affected by sludge type or soil type.
- Association Zn concentrations in fescuegrass were higher with municipal sludge.
- Association Zn concentrations in fescuegrass were higher with sandy clay loam.
- Association With municipal sludge, soil types had no effect on Cr and Pb concentrations in fescuegrass.
- Association With municipal sludge, Ni concentration in fescuegrass was higher with loamy sand.
- Association With municipal sludge, Cd concentration in fescuegrass was initially higher with sandy clay loam.
- Association Surface-applied sludge gave higher metal concentrations in grass than incorporated sludge.
- Association Cr and Pb concentrations were not affected by sludge compared with chemical fertilizer.
- Association Cu concentration increased due to sludge at first harvest only, compared with chemical fertilizer.
- Association Zn, Ni and Cd concentrations increased due to sludge, compared with chemical fertilizer.
- Association Heavy metal concentrations in grass were not consistently related to soil type.
- Recommendation A better criterion than CEC is needed for determining acceptable metal loading rates on major southeastern US soils.
