[Digestion] Manure biogas worms

[Murali Krishna]

Good day all,

We have been using biogas effluent and chopped crop waste for producing
vermicompost for the last 10 years.  We had also produced PROM, viz.,
Phosphate Rich Organic Manure (equivalent to DAP). Should anyone is
interested I can send some photographs.

Krishna.
