“…The genus Microdorylaimus was most abundant omnivore in our study with D =1.14 %. Ettema and Bongers (1993) discovered temporary increasing of abundance of genus Microdorylaimus on manured plots in contrast to untreated ones, therefore its high abundance was attributed to the organic treatment and indicated a possible relation between the abundant algae growth in the food-rich soil in summer and species abundance in the upper 15 cm of investigated soil profile, because of green intestine determined as algae. The water content, together with soil porosity, temperature and food webs are one of the main factors influenced the occurrence and abundance of soil nematodes (Yeates et al, 2002;Sohlenius & Boström, 2001).…”

Composition and vertical distribution of soil nematode communities within soil profile were investigated in eight hop gardens in Czech Republic. In total, the presence of 78 nematode genera was confirmed. Genus Drilocephalobus (Coomans & Coomans, 1990) is new for fauna of the Czech Republic. The highest abundance of soil nematodes was found at a depth of 0–10 cm and declined with increasing depth of soil profile. The most dominant genus was Bitylenchus, followed by genera Acrobeloides, Ditylenchus, Chiloplacus and Cervidelus. Ten genera of plant parasitic nematodes were recorded: Bitylenchus (with prevalence of B. dubius), Helicotylenchus, Heterodera (with absolute prevalence of H. humuli), Geocenamus, Longidorella, Longidorus (only L. elongatus), Merlinius (with prevalence of M. brevidens), Paratylenchus and Pratylenchus. Low population densities of predators and omnivores, low values of the community indices (MI, ΣMI, SI, and CI), and high values of NCR, EI, and PPI/MI ratio indicated disturbed nematode communities in hop gardens and bacteria-dominated decomposition pathways in the soil food web.

“…Rhabditidae, can be linked directly to higher populations of bacteria that are associated with the input of organic amendments like compost and slurry. Ettema and Bongers [17] found that the explosive growth of the rhabditid population, caused by the very high nutrient density, took place immediately after manuring and peaked after two or three weeks. Because of early reproduction, these colonizers escaped competition with other nematode groups.…”

“…Two weeks after this peak population had been reached, the numbers of these nematodes started to decrease again and about twenty weeks after manuring the population was reduced to less then one quarter of the peak population. Increased competition or parasitism might cause this decline in rhabditid numbers, but little is known of such interactions [17].…”

In Flanders, vegetable, fruit and garden (VFG) wastes are collected selectively and composted. We studied the effects of the combined application of three different doses of VFG compost and cattle slurry during 7 years on maize dry matter yields and three soil faunal groups: nematodes, micro-arthropods (springtails and mites) and earthworms. Combined application of VFG compost and slurry resulted in the highest yields. Initially, there was a clear yield depression on plots amended with compost in contrast to an upward trend in the last application years, proving a significant residual N effect from cumulative compost applications. The plant parasitic nematodes Pratylenchus sp. and the Tylenchidae were less abundant on plots receiving organic amendments, while the population of the bacteriophagous Rhabditidae was higher on these plots. Adding organic amendments resulted in increased numbers of micro-arthropods, springtails as well as mites. Earthworms were significantly more abundant when organic amendments were applied. The VFG compost had a larger overall positive effect on the three soil faunal groups than cattle slurry.

“…Nematofauna plays an important role in agro ecosystems and occupies a key position as primary and intermediate consumers in soil food webs; therefore, the study of the nematode community structure offers a powerful ecological tool for assessing soil disturbances and the effects of crops (Manachini, 2001). There has been an extensive assessment of their use as indicators of soil conditions, especially for their short-term response to environmental changes (Bongers, 1990;Ettema and Bongers, 1993;Yeates et al, 1993). Regarding the physical properties of the cultivated soils, aggregate stability and soil structure are considered as a key indicators of soil health (Arshad et al, 1996;Amézketa, 1999;Six et al, 1999;Duiker et al, 2003).…”

Most soil studies aim a better characterization of the system through indicators. In the present study nematofauna and soil structure were chosen as indicators to be assess soil health as related to agricultural practices. The field research was carried out on the two fodder cropping systems continuous maize (CM, Zea mays L.) and a 3-year rotation of silage-maize -silage-barley (Hordeum vulgare L.) with Italian ryegrass (R3) and grain-maize maintained in these conditions for 18 years. Each crop system was submitted to two management options: 1) the high input level (H), done as a conventional tillage, 2) the low input level (L), where the tillage was replaced by harrowing and the manure was reduced by 30%. The effects of the two different cropping systems was assessed on soil nematofauna and soil physic parameters (structure or aggregate stability). Comparison was made of general composition, trophic structure and biodiversity of the nematofauna collected in both systems. Differences in nematode genera composition and distribution between the two systems were also recorded. The monoculture, compared to the three year rotation, had a negative influence on the nematofauna composition and its ecological succession. The Structural Stability Index (SSI) values indicate that both the cropping systems had a negative effect on the aggregate stability. The results indicate that nematofauna can be used to assess the effects of cropping systems on soil ecosystem, and therefore be considered a good indicator of soil health to integrate information from different chemical or physical indicators.
