The Effect of Frequency of Rotational Burning on Blueberry Production

The results of a 9-year rotational burning study on blueberry fields at the Experimental Project Farm, Alliston, Prince Edward Island, indicated that total fruit production was greater from burning every second year than from every third year. Both burning treatments produced large yield increases over the unburned areas and injury from the blueberry maggot was largely controlled.Within the scope of this study, there was no evidence that flash burning, at either 2- or 3-year intervals, had seriously affected the rhizomes or the reserves of plant food in the soil.
