Endive requires high levels of potassium; it needs potassium at 2.5-fold higher than nitrogen! Optimal soil pH is 6.5 to 6.8, and liming may be needed if the pH is lower. Pre-plant application: approx. 65, 85-170, 115-230 kg/ha of N, P2O5, K2O, respectively. Side-dress application: for soils with over 3% organic matter, apply approx. 35 kg/ha of N. For soils with less than 3% organic matter, apply 50–65 kg/ha of N. Apply a total of 100–130 kg/ha of N.
