  abstract = {{T}he objective of this work was to assess the effects of conventional tillage and of different direct seeding mulch-based cropping systems ({DMC}) on soil nematofauna characteristics. {T}he long-term field experiment was carried out in the highlands of {M}adagascar on an andic {D}ystrustept soil. {S}oil samples were taken once a year during three successive years (14 to 16 years after installation of the treatments) from a 0-5-cm soil layer of a conventional tillage system and of three kinds of {DMC}: direct seeding on mulch from rotation soybean-maize residues; direct seeding of maize-maize rotation on living mulch of silverleaf ({D}esmodium uncinatum); direct seeding of bean ({P}haseolus vulgaris)-soybean rotation on living mulch of kikuyu grass ({P}ennisetum clandestinum). {T}he samples were compared with samples from natural fallows. {T}he soil nematofauna, characterized by the abundance of different trophic groups and indices ({MI}, maturity index; {EI} and {SI}, enrichment and structure indices), allowed the discrimination of the different cropping systems. {T}he different {DMC} treatments had a more complex soil food web than the tillage treatment: {SI} and {MI} were significantly greater in {DMC} systems. {M}oreover, {DMC} with dead mulch had a lower density of free-living nematodes than {DMC} with living mulch, which suggested a lower microbial activity.},
