ABSTRACT: The study was carried out in Baham district in the West Cameroon region,
as part of the recovery of organic waste with other biological components for
the manufacture of an organic fertilizer (improved biochar). Through
observations and a survey questionnairy submitted to 100 farmers, it appears
that the majority use synthetic chemical fertilizers. Farmers using chemical
fertilizers find them dangerous to their health. In addition, 58.57% of these
farmers said they felt unwell after spreading these fertilizers. However,
64.28% of these farmers do not acquire PPE for reasons of financial means on
the one hand and ignorance on the other hand. 54.28% of respondents using only
chemical fertilizers noted declining agricultural production. The surveys also
reveal that biochar (of plant origin) as a solution proposed by CIPCRE is used
by a minority of farmers (21%) in the said locality on the one hand and on the
other hand has limits in terms of intake nutrients for crops; this was
confirmed by analyzes of the physico-chemical parameters.
