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].
