Assessment of eutrophication potential from fertiliser application in agricultural systems in Thailand.

Releases of excess nitrogen and phosphorus from fertilisers applied in agricultural production cause eutrophication in the aquatic ecosystem. This study assessed the marine and freshwater eutrophication potentials associated with the fertiliser application in rice, maize, cassava, sugar cane and oil palm, cultivation in Thailand using a life cycle assessment characterisation model at midpoint and endpoint levels. The total marine eutrophication potential was 209,632,298 kg N eq while the total freshwater eutrophication potential was 2,044,136 kg PO eq.
