Evaluating the use of seaweed extracts against root knot nematodes: A meta-analytic approach.

Appl Soil Ecol 2021 Dec;168:None

Department of Biological Sciences, Royal Holloway University of London, Egham, Surrey TW20 0EX, UK.

Plant parasitic nematode (PPN) control has historically relied on the use of synthetic chemical nematicides, however many are toxic to both human health and the environment. The withdrawal of the more harmful nematicides coupled with increases in soil temperatures and increased occurrence of pests and diseases associated with climate change, may enable PPN to increase in numbers and spread globally. The need for sustainable and environmentally friendly management options is necessary while facing future food security scares in order to feed the ever-growing population. Read More

Next-generation sequencing of the soil nematode community enables the sustainability of banana plantations to be monitored.

Appl Soil Ecol 2021 Oct;166:None

Centre for Plant Sciences, School of Biology, University of Leeds, Leeds, UK.

Uganda faces a considerable challenge to match its food production to an annual population growth rate of 3%. Cooking bananas are the country's most produced staple crop but the annual national harvest is not increasing. The crop grows on infertile soils that are normally fertilised organically and often susceptible to erosion. Read More

Spatial structuring of soil microbial communities in commercial apple orchards.

Appl Soil Ecol 2018 Sep;130:1-12

NIAB EMR, East Malling, West Malling, Kent ME19 6BJ, UK.

Characterising spatial microbial community structure is important to understand and explain the consequences of continuous plantation of one crop species on the performance of subsequent crops, especially where this leads to reduced growth vigour and crop yield. We investigated the spatial structure, specifically distance-decay of similarity, of soil bacterial and fungal communities in two long-established orchards with contrasting agronomic characteristics. A spatially explicit sampling strategy was used to collect soil from under recently grubbed rows of apple trees and under the grassed aisles. Read More

Bacteria related to from Ghana are effective groundnut micro-symbionts.

Appl Soil Ecol 2018 Jun;127:41-50

Embrapa Agrobiologia, Rodovia BR 465 km 07, Seropédica, Rio de Janeiro 23891-000, Brazil.

The identification of locally-adapted rhizobia for effective inoculation of grain legumes in Africa's semiarid regions is strategic for developing and optimizing cheap nitrogen fixation technologies for smallholder farmers. This study was aimed at selecting and characterising effective native rhizobia, from Ghanaian soils for groundnut ( L.) inoculation. Read More

Changes in the genetic structure of an invasive earthworm species (, Lumbricidae) along an urban - rural gradient in North America.

Appl Soil Ecol 2017 Nov;120:265-272

Georg August University Göttingen, Johann Friedrich Blumenbach Institute of Zoology and Anthropology, Animal Ecology, Berliner Straße 28, 37073 Göttingen, Germany.

European earthworms were introduced to North America by European settlers about 400 years ago. Human-mediated introductions significantly contributed to the spread of European species, which commonly are used as fishing bait and are often disposed deliberately in the wild. We investigated the genetic structure of in a 100 km range south of Calgary, Canada, an area that likely was devoid of this species two decades ago. Read More

Is there sufficient and species diversity in UK farmland soils to support red clover (), white clover (), lucerne () and black medic ()?

Appl Soil Ecol 2017 Nov;120:35-43

School of Agriculture, Policy and Development, University of Reading, RG6 6AR, UK.

Rhizobia play important roles in agriculture owing to their ability to fix nitrogen through a symbiosis with legumes. The specificity of rhizobia-legume associations means that underused legume species may depend on seed inoculation with their rhizobial partners. For black medic () and lucerne () little is known about the natural prevalence of their rhizobial partner in UK soils, so that the need for inoculating them is unclear. Read More

Milled cereal straw accelerates earthworm () growth more than selected organic amendments.

Appl Soil Ecol 2017 May;113:166-177

Department of Sustainable Soils and Grassland Systems, Rothamsted Research, Harpenden, UK.

Earthworms benefit agriculture by providing several ecosystem services. Therefore, strategies to increase earthworm abundance and activity in agricultural soils should be identified, and encouraged. earthworms primarily feed on organic inputs to soils but it is not known which organic amendments are the most effective for increasing earthworm populations.

Identification and characterization of phages parasitic on bradyrhizobia nodulating groundnut ( L.) in South Africa.

Appl Soil Ecol 2016 Dec;108:334-340

Department of Chemistry, Tshwane University of Technology, Pretoria, South Africa.

In this study, three lytic phages (namely, PRSA-1, PRSA-2 and PRSA-26) were isolated and characterized for their morphology, host range, profile and restriction endonuclease banding pattern of genome size. The susceptible rhizobial isolates were identified by H and II sequence analysis. The results showed that all phages had polyhedral head with non-contractile tail which confirmed their relationship with the family. Read More

Effect of DNA extraction procedure, repeated extraction and ethidium monoazide (EMA)/propidium monoazide (PMA) treatment on overall DNA yield and impact on microbial fingerprints for bacteria, fungi and archaea in a reference soil.

Appl Soil Ecol 2015 Sep;93:56-64

Institute of Microbiology, University of Innsbruck, Technikerstr. 25, A-6020 Innsbruck, Austria.

Different DNA extraction protocols were evaluated on a reference soil. A wide difference was found in the total extractable DNA as derived from different extraction protocols. Concerning the DNA yield phenol-chloroform-isomyl alcohol extraction resulted in high DNA yield but also in a remarkable co-extraction of contaminants making PCR from undiluted DNA extracts impossible.

Impact of biotic and a-biotic parameters on structure and function of microbial communities living on sclerotia of the soil-borne pathogenic fungus .

Appl Soil Ecol 2011 Jun;48(2):193-200

Graz University of Technology, Institute for Environmental Biotechnology, Petersgasse 12, A-8010 Graz, Austria.

The plant pathogen is very difficult to control due to its persistent, long-living sclerotial structures in soil. Sclerotia are the main source of infection for diseases, which cause high yield losses on a broad host range world-wide. Little is known about micro-organisms associated with sclerotia in soil.

Changes in soil microbial community structure following the abandonment of agricultural terraces in mountainous areas of Eastern Spain.

Appl Soil Ecol 2009 Jul;42(3):315-323

GEA (Grupo de Edafología Ambiental). Departamento de Agroquímica y Medio Ambiente, Universidad Miguel Hernández, Avda. de la Universidad s/n, 03202-Elche, Alicante, Spain.

In Eastern Spain, almond trees have been cultivated in terraced orchards for centuries, forming an integral part of the Mediterranean forest scene. In the last decades, orchards have been abandoned due to changes in society. This study investigates effects of changes in land use from forest to agricultural land and the posterior land abandonment on soil microbial community, and the influence of soil physico-chemical properties on the microbial community composition (assessed as abundances of phospholipids fatty acids, PLFA).

Pathogens in livestock waste, their potential for movement through soil and environmental pollution.

Appl Soil Ecol 1995 Mar 19;2(1):1-15. Epub 2000 Jan 19.

Institute of Grassland and Environmental Research, Plas Gogerddan, Aberystwyth SY23 3EB, UK.

Livestock wastes contain many pathogenic microorganisms including bacteria, viruses and protozoa. Following the application of these wastes to land the potential exists for environmental contamination. Plants, soil and ultimately water courses which may subsequently be used as catchments for public water supplies may all be affected. Read More
