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.

Influence of Organic Matter in Sorption of the Saflufenacil in Ferralsols.

The saflufenacil herbicide has been applied in the agricultural areas as an efficient alternative for the control of resistant weeds to glyphosate. However, the environmental risks from the use of saflufenacil, especially in tropical soil, is not yet clearly known. We evaluated if the organic matter addition into the soil influences the sorption of saflufenacil in samples of a sandy and clayey texture soils.
