Dear Amrit & Upendra,

in your paper:
>Effluents (called "slurry") from biogas are safe for handling compared
>to raw excreta as pathogens are killed in course of anaerobic
>digestion process Such slurry has been proved to be a high quality
>organic fertilizer for plant nutrition.

Could you please brief me on the composition of what is accepted as Liquid NO3-fertilizer (ie the concentration limits of NO3, NH4,P,& K,SS, etc), from a nitrified effluent.

Thank You.
Christie
