Other claims from this paper (9)
- Intervention effect Early in summer, phosphorus was significantly lower in untreated black locust foliage than in insecticide-treated foliage.
- Intervention effect By late summer, phosphorus in untreated black locust foliage equalled that of insecticide-treated foliage.
- Association Potassium concentrations in untreated red maple foliage were significantly reduced in late summer.
- Association Calcium concentrations in untreated red maple foliage were significantly higher later in summer.
- Intervention effect Throughfall potassium in unprotected black locust trees was higher, 9.8 kg/ha, than in insecticide-protected trees, 5.7 kg/ha.
- Association Insecticide-treated black locust trees adsorbed 0.4 kg/ha of sulfate-S.
- Intervention effect Total biomass production of black locust was unaffected by the low levels of herbivory.
- Intervention effect Nominal herbivory did not stimulate biomass and nutrient accretion in these tree species.
- Association Herbivory may increase the cycling of K and perhaps other elements in these tree systems.
