Abstract

Until May 2021, the policy regime of the Government of Sri Lanka was to import and provide chemical fertilizer at subsidized rates to small-holder farmers. On May 6, 2021, the government imposed a ban on import of chemical fertilizers and subsidy was directed to organic fertilizers. Due to heavy protests by the farming community, the import ban was lifted in November 2021. By that time, fertilizer prices in the world market had sharply escalated making chemical fertilizers quite an expensive source of nutrients.
