Several studies carried out in commercial broccoli fields and other cool-season vegetables on the Central Coast found that no fertilizer N is necessary as long as the soil nitrate-N level is above 20 mg/kg (= 20 ppm) [N15, N18] .lder leaves have bright orange, red and purple tints and defoliate early.
