Abstract: 

The carrying capacity for microflora and nematofauna was manipulated
(using a bactericide, a fungicide, manure or a growing millet plant) in a
poor tropical soil, in order to identify relationships between the soil
microbes and nematodes and to assess the influences of these organisms
on nitrogen flux. The experiment was conducted for 4 months in
containers under greenhouse conditions, with analyses of soil,
nematofauna and microbial characteristics at regular intervals. Manure
input and initial bactericide application led to a significant increase
in bacterial-feeding and fungal-feeding nematodes of coloniser-persister
classes 1 and 2, respectively, whereas high manure input stimulated
omnivorous nematodes (i.e. Microdorylaimus rapsus) which became
the dominant trophic group. Changes in abundance of the different
bacterial-feeding nematode taxa between treatments seemed to be more
related to changes in the structure of the microbial communities than to
the total amount of micro-organisms, as suggested by the RISA
fingerprint analysis of the bacterial communities. Canonical analysis of
nematode feeding guilds, combined with soil microbial and mineral
nitrogen parameters as well as multiple regression showed that the
bacterial-feeding nematodes influenced the inorganic N content in the
soil whereas microbial biomass was determined by total nematode
abundance and not by any specific trophic group.
