Abstract : On the western coast of the Reunion Island, the tree fallow was abandoned for lack of land. Soil fertility is no longer restored and crop yields slump. The leguminous plant, #Lotus uliginosus# (trefoil) allows to control erosion, to restore soil macrofauna, especially that of earthworms and to increase the crop yield. When the trefoil is associatied with earthworms (#Amynthas corticis#), densities of maize and fertile maize plant density, the maize stalk and dry matter yield, the trefoil fodder dry matter yield, biomass and respiratory activity of soil microflora are considerably increased. The combined effects of their association decrease significantly the population of plant-parasitic nematodes (#Pratylenchus vulnus#) in the maize roots, the population of borer and some soil chemical features are modified.
