According to field surveys, most farmers admitted that they could not know whether the fertiliser that they had bought, either imported or produced domestically, was adulterated, except for some brands selling at a 50-100% premium. A test to check fertiliser quality should not cost much relative to the price of the fertiliser and could be made widely available (HKS, 2011). Three urea state-owned plants, built in the 1970s and run by the Myanmar Petrochemical Enterprise, produce around 100 000 tonnes per year, i.e. less than 25% of their capacity and around 17% of domestic requirements.
