Free-living nematode assemblages associated with maize residues and their ecological significance

Decomposition is a microbial process that involves the breakdown of complex organic compounds into less complex inorganic materials (De Mesel et al., 2006; Yadav et al., 2018). This process is fundamental for the release of immobilized nutrients such as nitrogen from plant residues into the soil. Plant residues, including maize leaves and stalks, provide energy to the soil food web in form of organic carbon and nitrogen, and also protect the soil against rain and wind erosion. In addition

Effects of integrated application of plant-based compost and urea on soil food web, soil properties, and yield and quality of a processing carrot cultivar

of inorganic fertilizers applied to soil and the accumulation of non-nutrient constituents such as heavy metals is an appealing strategy (Sikora and Knkiri, 2001). Implementation of such an alternative could be best achieved if its effects on soil food web, which drives nutrient transformations and productivity, are better understood. As the most abundant organisms in the terrestrial ecosystems and occurring at multiple levels of the soil food web, nematodes are key drivers of the soil food web

Influences of nitrogen inputs on nematode populations under highbush blueberry

has also been commonly observed to suppress certain populations of free-living soil nematodes, particularly omnivores and predators in the Dorylaimida with ‘persister’ or K-selected traits, resulting in reduced indices of diversity and food web structure such as the nematode community structure index (e.g. Ferris et al., 2001; Forge et al., 2005b; Wang et al., 2006; Azpilicueta et al., 2014; Pan et al., 2015; Song et al., 2016). Such changes in soil food web structure have been theoretically

Swine manure application enriches the soil food web in corn and soybean production

Soil food web indices From Midseason 2009 through Fall 2010, FBPP was significantly affected by crop sequence treatments (Table 4). Resistant soybean generally increased values compared with other treatments, but this varied by season (Table 4). In Midseason 2009, crop sequence effects varied by site (Table 4), and

Optimizing for taxonomic coverage: a comparison of methods to recover mesofauna from soil

nematodes and microarthropods are rare (Duncan et al., 2007), but will likely increase as affordable metagenomic tools provide wider opportunity to study cryptic soil communities. Relationships measured between biotic and abiotic variables in soil food web surveys can reveal potential key natural enemies of nematodes as well as cultural practices that manipulate the soil in ways to exploit the services of biological control agents of harmful nematodes and arthropod pests (Duncan et al., 2013; Campos

Effects of Cover Crops on Pratylenchus penetrans and the Nematode Community in Carrot Production

; radish compared to other cover crops or fallow control during cover crop growth and midseason carrot production. At both sites, there were few short-term impacts of cover cropping on soil ecology based on the nematode community. At Site 1, only at carrot harvest, radish-oats mixture and ‘Dwarf Essex’ rape alone enriched the soil food web based on the enrichment index (P ≤ 0.05) while rape and radish increased structure index values. At Site 2, bacterivore abundance

both trials. Although both VCTs did not reduce the number of M. incognita and R. reniformis in soil, weed VCT did increase omnivorous nematodes in the second trial, indicating a gradual improvement of soil food web structure through VCT drenching over time. Overall, performance of weed VCT was more consistent than vegetable VCT for plant-parasitic nematodes suppression.
