Thanks to the symbiosis with nitrogen fixing bacteria, white lupin doesn't need a nitrogen fertilisation, while it requires about 40 kg P2O5/ha and 60 kg K2O/ha. Fertilisations based on compost or composted manure are better than fresh manure. Thanks to its long tap root, white lupin can exploit well phosphorus reserves in the soil. The crop rotation for white lupin ideally lasts at least four, ideally five years and often lupin is grown after a cereal crop. Lupin is a good preculture, since it let in the field about 50 kg nitrogen/ha.
