FATE OF LABELLED FERTILIZER NITROGEN IN COMMERCIAL LOWBUSH BLUEBERRY STANDS

Open full text 13 citations

Abstract

Labelled fertilizer nitrogen (15N) was applied to four commercial lowbush blueberry stands in order to assess the fate of fertilizer N. Thirteen weeks after application, 45 and 64% of the labelled fertilizer N was recovered from blueberry plants at Debert and Pigeon Hill, respectively. This suggests rapid uptake of fertilizer N by blueberry plants. Sixteen months after application, an average of 67% of the fertilizer N was recovered from the four sites. The results of this study support other evidence suggesting that lowbush blueberry systems conserve fertilizer N. Key words: Blueberry, 15N, fertilizer
