- Abstract:
- ... We tested the potential for arbuscular mycorrhizal fungi to mediate plant adaptation to mine soil conditions utilizing a full factorial experiment involving two fungal communities, two ecotypes of plants and two soil types. We found that plants grew larger with fungal communities derived from mine soil regardless of the soil type in which they were grown. There was no evidence that the plants suff ...

- Abstract:
- ... A high-throughput assay was developed for the simultaneous quantification of various soil enzyme activities using p-nitrophenyl substrates. The average coefficients of variance (n =20) for assaying activities of N-acetyl-β-d-glucosaminidase, α-d-glucosidase, β-d-glucosidase, α-d-galactosidase, and β-d-galactosidase were 10, 15, 12, 18, and 16%, respectively. This assay makes it possible for system ...

- Abstract:
- ... Collembola are rarely included in landscape-level biodiversity assessments, large-scale surveys and monitoring projects because huge numbers of specimens would accumulate even in moderately sized programmes. Budgets are always limited, so sampling methods and identification need to be optimized. As no single sampling method collects all collembolan species equally well, we tested the efficiency of ...

- Abstract:

Three composts (produced with 0%, 8% and 16% wood ash admixture, respectively), and two acid tropical soils, an Oxisol and an Ultisol from Cameroon were used for that purpose. In this paper we report the effects on the soil microbiota at the end of the cropping cycle (100 days soybea ...

We present novel findings highlighting the early effects of inoculation of downy birch (Betula pubescens Ehrh.) seedlings with factorial combinations of beneficial soil fungi, namely, ectomycorrhizal and insect pathogenic fungi, on Otiorhynchus spp. larval root herbivory under Icelandic field conditions. Birch seedlings were pre-treated with (1) a mixture of four ectomycorrhizal fungal species: Pa ...

- Abstract:
- ... Increases in fertilizer inputs and livestock numbers affect plant species composition and richness; this in turn can affect the biodiversity of soil fauna and nutrient cycling in pastures. We selected two adjacent farmlets to study these effects. Since 1980, one farmlet (LF) had not received superphosphate fertilizer (SSP) and has a low stock density of sheep, and the other (HF) had received 37.5g ...

The influences of winter climate on terrestrial ecosystem processes have been the subject of growing attention, which is necessary to make the predictions about ecological responses to global warming in the future. However, little information can be found about the impacts of a large range of soil temperature fluctuation (e.g. −10 to 5°C) over winter on the soil nitrogen (N) dynamics in the field. ...

For the purpose of feeding value, drought resistance and nitrogen utilization, other grasses (e.g. Festuca arundinacea and Dactylis glomerata) than the currently widely used perennial rye grass (Lolium perenne) are introduced in dairy farming, either as a monoculture or in a mixture. To study the effect of these grasses on yield and soil chemical and biological quality, the three species were sown ...

The objective of this laboratory study was to determine the influence of a tropical endogeic earthworm, Pontoscolex corethrurus, on CO2 and N2O fluxes from a tropical Ferralsol and microorganisms potentially involved in these gases emissions. CO2 and N2O fluxes were measured during 35 days from soil mesocosms with and without earthworms. At the end of the incubation, 7% of soil was egested as cast ...

The role of phosphorus (P) application and arbuscular mycorrhizal fungi (AMF) on growth, arsenic (As) and P accumulation in lettuce plants growing in an As-polluted soil (total As 250mgkg⁻¹), was investigated. In particular, it was tested whether application of a commercial inoculum (CI), with (+P at 90kgPha⁻¹) and without (−P at 0kgPha⁻¹) P fertilizer, supported greater plant growth and provided ...

- Abstract:

Both primary and secondary metabolites and the expression of stress-responsive genes of plants can be affected by earthworms. Plant-mediated effects of earthworms on aboveground herbivore performance range between positive and negative. These indirect, plant-mediated effects likely depend on the altered resource up ...

- Abstract:
- ... Earthworms play an important role in soil fertility because of their effects on soil properties, and especially the creation of casts that usually have different properties than the surrounding soil. If the influence of earthworms on soil properties and plant growth has been extensively studied in aerobic ecosystems, their effects remain largely unknown in partially flooded environments such as pa ...

Thirty actinomycete strains were isolated from the rhizosphere of field-grown plants (Trifolium repens L.) and identified by microscopic characteristics, biochemical tests and molecular techniques.

These thirty isolates were tested for their capabilities of solubilizing/mineralizing sparingly phosphat ...

- Abstract:

The EPN Steinernema riobrave infects many different types of soil insects, including larvae of the invasive citrus root weevil, Diaprepes abbreviatus, which is a key pest in citrus production. Soil characteristics have a great impact on nematode foraging efficacy and therefore on the ab ...
