Seasonal N Uptake



Nitrogen in prune trees [9]. Nitrogen uptake from soil is minimal during dormancy and low during bud swell. Nitrogen uptake is greatest during the summer and early fall [7].


Nitrogen Partitioning



Nitrogen distribution in 12-year old heavily cropping prune trees. Whole trees were excavated and analyzed at prune harvest [9].


Nitrogen Removed at Harvest

Nitrogen removed with harvested prunes and plums. The values include N removed in fruits and pits. The overall average is weighted for the number of observations in each trial. More information can be found here [2].
