Seasonal N Uptake

The N uptake curve is based on data from eight summer-planted commercial cauliflower fields in the Salinas Valley ^[3].

Nitrogen Partitioning

Less than one third of the total aboveground N is removed with the harvested parts ^[1,2].

Nitrogen Removed at Harvest

Cauliflower yield and N removed at harvest from different studies.
