Production of pine sawdust biochar supporting phosphate-solubilizing bacteria as an alternative bioinoculant in Allium cepa L., culture.

We produced and characterised biochar made from Caribbean pine sawdust as raw material. The biochar (BC) was used as biocompatible support to co-inoculate phosphate solubilizing bacteria (PSB) (BC/PSB) on Allium cepa L., plants at a greenhouse scale for four months.
