Strawberry Nitrogen Uptake and Partitioning
The Fertilization guidelines can also be found on the UC Davis Nutrient Management website .
Seasonal N Uptake
In commercial fields in the Salinas and Pajaro Valleys, aboveground biomass N accumulation averaged approximately 20 lbs/acre through March. From April through mid-September, aboveground biomass N increased linearly, reaching on average 190 lbs/acre [1].
Nitrogen Partitioning
Approximately half of the aboveground N was in the strawberries, while the other half was in the leaves and the crown [1].
Nitrogen Removed at Harvest
Strawberry yield and N removed at harvest.
Location | Years | Yield | Aboveground N | Harvested N | Source | ||
