e0“southern highbush blueberry (Vaccinium corymbosum interspecific hybrid) cultivars were planted at a density of 10,000 plants per ha in southwest Florida”
e1“There was no consistent effect of N rates on soil nutrient concentrations, but leaf N increased and leaf Ca decreased as N rate increased”

Other claims from this paper (11)
- Intervention effect Increasing N rates increased plant canopy volume, leaf retention and the rate of new vegetative budbreak of blueberry in southwest Florida.
- Intervention effect Leaf N of blueberry increased as N rate increased.
- Intervention effect Leaf Ca of blueberry decreased as N rate increased.
- Intervention effect MSW compost increased soil P, Ca and Mg concentrations compared with peat.
- Intervention effect MSW compost increased soil Cu, Fe and Mn concentrations compared with peat.
- Intervention effect MSW compost increased soil Zn concentration compared with peat.
- Intervention effect MSW compost had no consistent effect on leaf nutrient concentrations compared with peat.
- Intervention effect Plant height and canopy volume were greater with MSW compost than with peat amendment.
- Intervention effect Leaf retention and vegetative budbreak did not differ between MSW compost and peat amendment.
- Observation Plants in the non-dormant system showed no deleterious growth effects.
- Recommendation Establishing a blueberry planting in a warm winter climate is feasible under the described conditions.
