“…The average value of H' was 8.5% lower in the disease area than in the control area, while that of λ was 23.3% higher in the disease area than in the control area, which was in agreement with the results of Pattison et al (2008) in north Queensland. These apparent differences were attributed to a decline in abundance of omnivorespredators and enhancement in abundance of fungivores in the disease area (Neher et al, 2005).…”

“…Nematodes are heterotrophs in the higher food chain compared to microorganisms and serve as integrators of soil pro-perties and environment disturbance related to their food source, predators and parasites (Ferris, 2010). They show rapid reaction to the disturbance or stress caused by banana wilt disease in temperate and tropical regions (Pattison et al, 2008). Both the classification of soil nematodes into trophic groups and understanding of nematode life strategies, whether colonisers or persisters (c-p), are useful measurement to detect the changes of soil microbial composition in banana wilt disease areas and provide information about the level of disturbance (Berkelmans et al, 2003;Stirling et al, 2004).…”

Effects of banana wilt disease caused by Fusarium oxysporum f. sp. cubense (FOC) on soil nematode community composition were investigated in Hainan province China. The results show that 31 nematode genera in the disease and control regions were identified. The disease area was mainly dominated by Acrobeles, Acrobeloides, Chiloplacus and Aphelenchus, while Pelodera, Protorhabditis, Ditylenchus and Basiria dominated in the control area. Paratylenchus was the dominant genus in both areas. The abundance of total nematodes, bacterivore (10 to 30 cm), plant parasites and omnivorespredators, the values of diversity (H′), maturity index (MI), plant parasite index (PPI), structure index (SI), enrichment index (EI), soil pH, the contents of total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP) and alkaline nitrogen (AN) in the disease area were significantly lower (P < 0.01) than in the control. However, those of fungivores (10 to 20 cm) and dominance (λ) exhibited quite a reverse result. In the disease area, the abundance of total nematodes and bacterivore decreased (P < 0.01) and plant parasites increased (P<0.01) with the increase of soil depth. The values of SI increased (P <0.01) with the increase of soil depth in the disease and control areas in 0 to 20 cm. The results indicate that FOC changed soil nematode community characteristics and decreased diversity of soil nematode community.

“…High levels of biodiversity are thought to enhance stability of soil functions and services against perturbations and disturbances, and aid in the suppression of soil-borne pests and diseases (Griffiths et al, 2000;Altieri, 1999;Barrios, 2007). Soil biodiversity is also recognised as a sensitive biological indicator for effects of environmental change and disturbance (Wardle et al, 1995;Ritz et al, 2009;Pattison et al, 2008;Ponge et al, 2006). One of the key indicator groups is the soil microarthropods, because these are abundant, functionally diverse, and respond to a variety of ecological and environmental factors (Gardi and Parisi, 2002;Parisi et al, 2005).…”

Abstract. Intensive agricultural production can be an important driver for the loss of long-term soil quality. For this reason, the European Critical Zone Observatory (CZO) network adopted four pairs of agricultural CZO sites that differ in their management: conventional or organic. The CZO sites include two pairs of grassland farms in Iceland and two pairs of arable farms in Austria. Conventional fields differed from the organic fields in the use of artificial fertilisers and pesticides. Soils of these eight farms were analysed in terms of their physical, chemical, and biological properties, including soil aggregate size distribution, soil organic matter contents, abundance of soil microbes and soil fauna, and taxonomic diversity of soil microarthropods. In Icelandic grasslands, organically farmed soils had larger mean weight diameters of soil aggregates than the conventional farms, while there were no differences on the Austrian farms. Organic farming did not systematically influence organic matter contents or composition, nor soil carbon and nitrogen contents. Also, soil food web structures, in terms of presence of trophic groups of soil organisms, were highly similar among all farms, indicating a low sensitivity of trophic structure to land use or climate. However, soil organism biomass, especially of bacteria and nematodes, was consistently higher on organic farms than on conventional farms. Within the microarthropods, taxonomic diversity was systematically higher in the organic farms compared to the conventional farms. This difference was found across countries and farm, crop, and soil types. The results do not show systematic differences in physical and chemical properties between organic and conventional farms, but confirm that organic farming can enhance soil biomass and that microarthropod diversity is a sensitive and consistent indicator for land management.

“…Segundo Pattison et al (2008), Mondino et al (2009) e Cardoso et al (2012, os nematoides apresentam grande potencial como bioindicadores de qualidade do solo devido à resposta rápida às mudanças no ambiente e ações de gestão do solo. Neste estudo objetivou-se avaliar o efeito de quatro níveis de compactação de solo infestado com M. incognita no desenvolvimento inicial de plantas de canade-açúcar.…”

R E S U M OEm áreas cultivadas com cana-de-açúcar no Nordeste do Brasil, a compactação do solo e a presença de altas densidades populacionais de nematoides, principalmente Meloidogyne spp. restringem severamente a produtividade agrícola. O presente estudo teve como objetivo avaliar o efeito de quatro níveis de densidade do solo infestado por nematoides da espécie M. incognita no desenvolvimento inicial da cana-de-açúcar, variedade RB 863129, em condições de casa de vegetação. As avaliações, realizadas 90 dias após a infestação do solo, se fundamentaram na altura da planta, diâmetro do colmo, número de folhas, biomassa fresca das raízes, biomassa fresca e biomassa seca da parte aérea, número de ovos do nematoide por grama de raiz. O aumento dos níveis de compactação do solo de 1,65 para 1,82 kg dm -3 proporcionou redução na multiplicação de M. incognita e aumento no comprimento do colmo da cana-de-açúcar mas não afetou as outras variáveis de desenvolvimento da planta.Influence of density of soil infested with nematode on initial growth of sugarcane A B S T R A C TIn cultivated areas of sugarcane in Northeastern Brazil, soil compaction and infestation of nematodes, mainly Meloidogyne spp., severely restrict crop production. The present study aimed to evaluate the effect of four levels of density of soil infested with nematodes of the species M. incognita in the early development of sugarcane variety RB 863129 in greenhouse conditions. Evaluations were carried out 90 days after soil infestation, based on plant height, stalk diameter, number of leaves, root and shoot fresh biomass, shoot dry biomass and number of nematode eggs. The increase in soil compaction level from 1.65 to 1.82 kg dm -3 decreased M. incognita reproduction and increased sugarcane stalk length, but it did not affect the other plant development variables. Palavras IntroduçãoAtualmente, a cultura da cana-de-açúcar (Saccharum L.) se reveste de grande importância socioeconômica para o Brasil enquanto a aceitação internacional do etanol como combustível aliado à lucratividade alcançada pelo setor sucroalcooleiro, tem trazido euforia aos produtores de cana-de-açúcar, com reflexos na intensificação e na expansão do seu cultivo. Dentre os fatores de produção relacionados com a modernização da canavicultura brasileira, o crescimento da demanda pela colheita mecanizada se destaca intensificando o tráfego sobre o solo, muitas vezes em condições desfavoráveis em termos de conteúdo de água, tornando praticamente inevitável a ocorrência da compactação do solo (Iaia et al., 2006; Vicente, 2011).A compactação, resultado do processo de aumento da densidade do solo e resistência à penetração, é uma das principais causas da degradação do solo. Assim, o tráfego de máquinas vem intensificando o processo de compactação em virtude de promover alterações nas propriedades físicas dos solos afetando diretamente a qualidade do solo e da água e trazendo, como consequência, alterações no crescimento e na produtividade da cultura, além do aumento dos processos erosivos (Bord...
