The 22 bio-fertilizer units in Tamil Nadu annually produced about 3,000 metric tonnes of carrier-based bio-fertilizer and five lakh litres of liquid bio-fertilizer, P. Raja, Assistant Director of Agriculture (technical) and member of State technical team for bio-fertiliser units has said.
Of the 22 units, 10 units exclusively produced carrier-based bio-fertilizers in powder form, mixed in pulverised lignite coal, seven units had been set up to exclusively produce liquid bio-fertilizer and five units produced both carrier-based and liquid bio-fertilizers, he said.
After the State government issued the Government Order on July 29, 1986 for establishing bio-fertilizer units in the State, the first unit was set up in Cuddalore and the second in Ramanathapuram, he said.
After former Chief Minister Jayalalithaa made an announcement on the floor of the Assembly under rule 110 in 2015, seven exclusive liquid bio-fertilizer units were established in the State.
While the units in Manamadurai, Madurai, Palani, Jayamkondam in Ariyalur and Kudiyatham in Vellore districts started production recently, units in Mugaiyur in Villupuram district and Puzhal in Thiruvallur district were expected to commence production later this month, he said.
