Strawberry Nitrogen Uptake and Partitioning
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 .
Approximately half of the aboveground N was in the strawberries, while the other half was in the leaves and the crown .
