Biodiversity in soil systems is high relative to above ground systems and nematodes are first-rate bioindicators for monitoring the biological quality of soils. They have a significant impact on soil processes, especially through their influence on biomass and microbial populations and also they play an important role in soil food web, mineralisation and nutrient re-cycling (Chen et al 2009;Landi et al 2017;Brmež et al 2018).The direct or indirect disturbance as tillage, pesticide use, fertilization, liming, salinization etc., lead to alterations in community structure at all trophic levels and thereby disturb the functioning of the en-tire agroecosystem (Timper 2014;Moura, Franzener 2017; Kristek et al 2018).In agricultural soils along with free-living nematodes as fungal feeders, omnivores and predators (Yeates et al 1993), there are an increased number of bacterial feeders (Neher et al 2004;Grubišić et al 2016) and plant parasitic nematodes. Bacterial feeders nematodes are more common in agricultural and grassland systems, whereas fungal feeders nematodes are more important in forests.Soil acidity has determinal effect on plants and soil organisms, so the activities and functioning of soil organisms are generally reduced which results in inhibi-

Monitoring the biological quality of soils often include nematodes as bioindicators. The aim of this study was determined the influence of liming, P and Zn effect on nematode community structure as an indicator of soil ecosystem health in hot pepper. Pot experiment with hot pepper was conducted in randomized block design as follows: control, P, Zn, P + Zn, lime, P + lime, Zn + lime and P + Zn + lime (25 mg/kg P, 1 mg/kg Zn and lime as 2.22 g/kg CaCO3). The highest number of nematodes genera was with phosphorus application (17.25). The most common genera were Rhabditis and Tylenchus. Above all indices, only the Structure index (SI) shown significance (P < 0.01) in reflecting soil disturbance. The highest significant correlation was found between Maturity index 2–5 and Structure index <br />(r = 0.946***), Maturity index and Plant parasitic nematode and Maturity index ratio (r = –0.919***) and between Ecological and Channel index (r = –0.815***).

“…The genus Rhabditis was present in the greatest abundance in soils fertilized using poultry litter and cow manure, and the higher abundance of Acrobeles was observed in coffee plantation fertilized with cow manure. These genera belong to groups of opportunistic nematodes and rapidly respond to the incorporation of organic fertilizers from animal origin in the soil and are usually more abundant in agricultural areas ( Brmež et al, 2018 ; Carron et al, 2015 ; Van den Hoogen et al, 2020 ). The abundance of members of this family contribute to the mineralization and regulation of nutrients such as nitrogen, which is then available for the trees ( Ferris et al, 1998 ; Sãnchez-Moreno et al, 2011 ).…”

In conventional coffee farming, soil fauna can be negatively affected by the intensive management practices adopted and the use of an agroforestry system (AFS) is an alternative to reduce these impacts. In coffee AFS, soil nutrition is provided mainly using organic fertilizers. This soil management favors the microbiota and can alter the population dynamics of some organisms. Our objective was to evaluate the effect of organic fertilizers on the nematode community in coffee AFS and to determine their impact on soil ecology. Soil samples were collected from three coffee AFS and a nearby Atlantic rainforest fragment. Nematodes were extracted from the samples and identified to the genus. The identified populations were compared using several community and diversity indices to determine the environmental conditions of the systems under evaluation. No differences in total abundance among nematode communities were found in the four areas evaluated. Regarding trophic groups, the coffee AFS treated with either cow manure or poultry litter favored the trophic group of bacterivores. Plant-parasitic nematodes were more abundant in soils of both the naturally fertilized coffee AFS and the Atlantic rainforest fragment. The maturity and structural indexes indicated that the Atlantic rainforest fragment and the naturally fertilized coffee AFS had similar ecological functions. On the other hand, soils fertilized with cow manure were less diverse, had higher dominance in the community, and showed less ecological stability. The nematode communities found in the AFS were similar to those seen in the forest fragment indicating that is possible to produce coffee sustainably without negatively affecting soil quality.

“…A community structure study of soil organisms such as the nematodes may provide us with an insight into the soil processes and the soil status (Ritz and Tradgill, 1999). The nematodes are used as bioindicators because of their ubiquity, diversity, and abundance and because of their rapid reaction to the environmental changes (Neher at al., 2005;Brmež et al, 2018). The nematode communities are studied to estimate the soil disturbances and to monitor the soil's ecological condition (Bongers, 1990;de Goede, 1993).…”

An above‐ground plant diversity affects a below-ground biodiversity. A soil fauna diversity is important for the ecosystems’ sustainability. It reflects both the abiotic conditions and the soil’s biotic activity. This study’s objective was to assess the effect of an agroforestry system on the nematode abundance and trophic group distribution and on the bacterial and fungal abundance in the soil, as well as to analyze the links between a nematode abundance, trophic group patterns, soil’s microbiological status and the organic matter. A field experiment was conducted during two years in three treatments and three sampling periods. The treatments were as follows: an agricultural crop (C), a permanent walnut plantation (W), and a permanent walnut plantation with an agricultural crop (C + W). The nematodes were extracted, counted, processed and mounted on slides and ultimately determined and assigned to the trophic groups. The bacteria and fungi were extracted from the soil, grown on the plates, and counted. Our findings suggest that the studied agroforestry system (C+W) has exerted a positive effect on the soil nematodes, bacteria, and fungi, manifested as the statistically highest abundance of bacteria and fungi, but also as the highest abundance of nematodes and of a diversity of the nematode genera. The highest content of the organic matter was detected in the treatment C + W in the first sampling and in the treatments C + W and W in the second sampling. We have concluded that the combination of an agricultural crop and a permanent plantation has a great potential for better ecosystem stability and sustainability regardless of some deviations in our results. We believe that further research is necessary because the different agroforestry ecosystems may have different impacts on the soil fauna.
