Nutrient

Nutrient rate required
(should be low right after harvest and grow gradually parallely to plant growth)

N

1 kg/ha for the first week after harvest, up to 4 kg/ha for the week before next harvest. Should total 80 kg/ha of N between harvests.
In case of soilless culture the use of a high-N Poly-Feed Drip formula with ME is needed (e.g. 26-12-12 + 2MgO+ME). Apply 70 ppm N on the first week after harvest and increase it up to 120 ppm N for the week before next harvest.

P

Total 10 kg/ha of P2O5 (15 kg/ha of MAP) between harvests.

K

Total 40 kg/ha of K2O (87 kg/ha Multi-K) between harvests.
