that soil food web changes are forage type and cultivation dependent [34, 50–52]. A
piecewise proceeding structural equation modelling (SEM), used to test relationships
between soil invertebrates response variables and abundance variation, reveals that
group of invertebrates may be selectively affected by soil phosphorus availability,
soil aggregate stability, soil moisture and in dependency of soil respiration type, the
availability of weed or of the produced sorghum sudan grass biomass [53].
The soil fauna members (Table 1) have developed metabolism strategies, selective feeding behaviours, and different morphological shapes allowing to adapt on
