“…An increase of plant-feeding nematodes intensifies root C fluxes activating microbial biomass from the rhizosphere and microbivorous nematodes stimulate microorganisms (Denton et al, 1999). Conversely, as there were more microorganisms in Organic plots, we consistently found more fungal-feeding nematode density in organic plots, which is in line with Ferris et al (1996), Villenave et al (2004) and Villenave et al (2010). However, only an increasing trend was observed for bacterial-feeding nematode density in Organic plots.…”

a b s t r a c tThe rate of conversion of conventional vineyards into organic farming is currently increasing. This results in modifications of agricultural practices such as the application of organic manure, the use of tillage or grass-cutting to control weeds and the application of natural pesticides with preventive action. One of the aims of organic farming is to preserve the environment. In this context, the objective of our work was to evaluate the long-term effects of organic viticulture on soil quality. The study was conducted in a commercial vineyard where plots which had been organically managed for 7 (Organic7), 11 (Organic11) and 17 years (Organic17) were compared to conventionally managed plots (Conventional). Soil physical and chemical parameters (bulk density, organic matter, available phosphorus, potassium and copper contents) and biological parameters (soil microbial biomass, density of nematode trophic groups and density and biomass of earthworm ecological categories) were measured. The organic farming led to an increase in soil organic matter, potassium content, soil microbial biomass, plant-feeding and fungalfeeding nematode densities. However, organic farming increased soil compaction, decreased endogeic earthworm density and did not modify the soil micro-food web evaluated by nematofauna analysis. Our study highlights the difficulty to show the benefits of organic farming on global soil quality in this particular pedoclimatic area and set of farming practices.

“…The response of nematode community to organic manure tends to be controlled by the amount of organic carbon (C) and quality of the organic material (McSorley & Frederick, 1999). For instance, the number of plant-feeding nematodes was significantly higher in plots fertilised with manure than plots amended with straw, whilst the opposite trend was observed for fungalfeeding nematodes (Villenave et al, 2010). Changes in nematode community structure were also observed after addition of inorganic nitrogen (N), phosphorus (P) and potassium (K) fertilisers, although nematode density and community responses were weaker with inorganic than organic fertilisers, presumably because organic C is more effective in boosting microbial biomass that is a food source for the bacterivore, fungivore and omnivore nematodes (Bulluck III et al, 2002;Hu & Cao, 2008;Liang et al, 2009).…”

The practice of growing agricultural crops in rows results in larger soil nematode populations in the root-associated soil than in the bulk soil between the rows. Fertilisers applied to improve grain yield generally increase the abundance of nematode communities in agricultural soils. The objective of this study was to compare total nematode density and four dominant genera in the root-associated and bulk soils of paddy rice and upland wheat receiving organic and mineral fertilisers. Dominant nematode genera accounted for 80% of all nematodes and represented four trophic groups. There was greater total nematode density and a higher enrichment index (EI) but less nematode diversity (H ) and a lower structure index (SI) in the root-associated soil than bulk soil of upland wheat. By contrast, nematode abundance, diversity and ecological indices were similar in the root-associated and bulk soils of the paddy rice. Soil nematode communities were affected significantly and consistently by fertilisation in upland wheat and paddy rice phases. More herbivore Hirschmanniella were present with mineral fertiliser than in the non-fertilised control. Straw-based organic fertilisers increased the abundance of bacterivore Eucephalobus. The lack of interaction between rhizosphere effect and fertilisation indicated that crop-growing conditions (different species and water regimes) were more influential on nematode communities and not consistently impacted by short-term organic and mineral fertilisation in the rice-wheat agroecosystem.

“…Parmi elles, T. martini et P. brachyurus ont été signalées comme des espèces liées à la culture du sorgho. En particulier, P. brachyurus est signalée comme un nématode omniprésent, fréquemment lié à la culture du sorgho (Motalaote et al, 1987 ;Mc Donald et Nicol, 2005 ;Talwana et al, 2008 ;Villenave et al, 2010). Nos résultats montrent que les taux d'infestation des différents nématodes varient d'une rotation à une autre.…”

RESUMEL'infestation du sol et des racines du sorgho (sorghum bicolor (L.) Moench) par les nématodes phytoparasites a été étudiée en 2008 sur un essai agricole à l'Ouest du Burkina Faso. Cet essai agricole est représentatif de la production du sorgho avec utilisation de différentes pratiques agricoles incluant la rotation culturale, l'apport de matières organiques exogènes et une fertilisation minérale. L'objectif était de déterminer l'effet de ces pratiques sur les taux d'infestation du sol et des racines par les nématodes. Les nématodes du sol ont été extraits selon la méthode de « l'élutriateur » de Seinhorst et ceux des racines selon la méthode de « l'asperseur » de Seinhorst. Le sol et les racines du sorgho ont été plus infestés par les nématodes dans la monoculture de sorgho par rapport aux rotations sorgho -niébé et sorgho -coton. Les traitements incluant la matière organique et la fertilisation minérale ont été moins infestés par les nématodes par rapport aux traitements utilisant uniquement une fertilisation minérale. La nématofaune de la jachère a été plus diversifiée que celle du site cultivé et le principal nématode lié au sorgho, P. brachyurus, y a fortement régressé.
