In his letter, Tasa has said that he has been receiving complaints from various stakeholders that some fertilizer manufacturers are supplying poor-quality fertilizers in the State, thereby causing huge loss to the farmers here. Tasa says he has also learnt some officials with “unholy alliance with dubious suppliers” on the plea of maketing tie-ups with urea, DAP and MOP manufacturers have “in fact allotted urea/DAP/MOP to dealers against lifting of dubious fertilizers, more particularly in the case of single super phosphate, zinc, growth promoters, soil enhancers etc”.
