Sustainability nan tou de agrikilti ak enèji yo se pwoblèm enpòtan pou 21yèm syèk la. Pwodiksyon agrikòl depann sou aplikasyon nan angrè yo reyalize pwodiksyon an segondè, men fosfat wòch se yon resous ki limite, pwosesis li nan angrè se enèji entansif ak anviwònman an domaje, ak dlo nan dezè soti nan tou de pwosesis agrikòl ak iben gen nivo nan Fosfò (prensipalman kòm fosfat) ak Azòt ki ka mennen nan eutrophication etwofizasyon nan kò dlo.

Sustainability in both agriculture and energy are important issues for the 21st century. Agricultural production depends upon application of fertilisers to achieve high yields but rock phosphate is a limited resource, its processing to fertiliser is energy intensive and environmentally damaging, and waste water from both agricultural and urban processes contain levels of Phosphorus (primarily as phosphate) and Nitrogen that can lead to eutrophication of water bodies.
