Organic or conventional production system and nutrient rate affect the nematode community in carrot production

Conservation Services, 2020). The nematode community is an important biological component of soil health because it can contribute to sustained soil productivity and can be a useful indicator of agroecosystem status (Grabau et al., 2020; Trap et al., 2016). The nematode community includes both plant-parasitic nematodes that parasitize and damage crops and free-living nematodes, which may be beneficial to soil productivity (Ferris et al., 2001; Grabau et al., 2018). Free-living nematodes include a wide

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

improving soil fertility and quality (Bao et al., 2013). In addition to physical and chemical components provided by fertilizers, biological components, such as free-living nematodes and the soil-dwelling organisms associated with them, are important contributors to soil nutrient cycling and quality. Fertilizer application may influence soil ecology and the nematode community because it provides an influx of nutrients and other compounds. Application of animal manures or plant-based fertilizers may

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

Cover cropping is a common practice in U.S. Midwest carrot production for soil conservation, and may affect soil ecology and plant-parasitic nematodes—to which carrots are very susceptible. This study assessed the impact of cover crops—oats (Avena sativa), radish (Raphanus sativus) cv. Defender, rape (Brassica napus) cv. Dwarf Essex, and a mixture of oats and radish—on plantparasitic nematodes and soil ecology based on the nematode community in Michigan carrot

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

(indicator of food web status affected by stress or disturbance) as described by Ferris et al. (2001). While there are several studies on the impact of organic amendments and inorganic fertilizer on nematode community, soil fertility, and plant productivity (Bulluck et al., 2002a; Briar et al., 2007), the impact of mixed compost-fertilizer applications on soil nematodes community structure and overall soil food web health is less understood. The objectives of this study were to compare the effects of

Nematicide effects on non-target nematodes in bermudagrass

; Ferris and Bongers, 2006). Studying population changes of nematode functional groups can provide insight into potential effects of nematicides on soil health (Ferris et al., 2001). We conducted nematicide treatment programs in order to better understand potential non-target effects on non-herbivore free-living nematode community structure. We predicted nematicide applications would significantly affect nematode community structure by decreasing the number of nematodes belonging to high trophic levels

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

Nematicide efficacy at managing Meloidogyne arenaria and non-target effects on free-living nematodes in peanut production

. Nematodes were extracted from soil by sucrose-centrifugation (Byrd et al., 1976) and the nematode community (plant-parasitic and free-living nematodes) was quantified morphologically using an inverted light microscope. Nematode abundances by trophic group (herbivores, fungivores, bacterivores, and omnivores plus predators) were calculated and analyzed (Yeates et al., 1993). Abundances of individual genera that were consistently present in most plots were also analyzed. Genera analyzed included the

Nematodes and the effect of seasonality in grassland habitats of South Africa

dependant on the presence of vegetation with the smallest effect recorded in grasses. Ultimately, understanding how seasonal variation affects soil ecosystems is necessary in order to accurately assess and monitor the potential threats posed by anthropogenic activities and climate change. For these reasons, this study was undertaken and aimed at (i) studying the nematode community structure in the open grassland, shrubland with rocky outcrops and riparian zone habitats of the Telperion Nature Reserve

Organic fertilization influences nematode diversity and maturity index in coffee tree plantations using an agroforestry system

fertilization (Ferris, 2010; Oka, 2010). Studies on the diversity of nematodes in agricultural areas have resulted in a growing interest in this field as these organisms can act as bioindicators for agroecosystems (Neher, 2001). Depending on the fertilizer used, the availability of soil nutrients is altered and this reflects on the nematode community (Yeates et al., 2009; Zhang et al., 2019). Organic fertilization can provide nutrients for the development of bacterial-feeding nematodes and reduce the
