Prospects for the integrated development of lignite deposits in Zakarpattia as a source of critical mineral raw materials

open access: yesМінеральні ресурси України
An analysis of critical mineral raw materials was carried out based on the Report of the US Department of Energy (DOE) “Evaluation of Critical Materials”, which was issued in the USA in July 2023, as well as the Methodology for the determination of ...

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

open access: yesPest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Technological prerequisites and methods of germanium extraction on the example of lignite deposits of Zakarpattia

open access: yesМінеральні ресурси України
This article is about the chemical element germanium, which has become one of the most important materials today. Germanium, which is a trace element, was isolated mainly from the products of other mines and from ore rocks.

Estimating bioavailable reserves and potential leaching of soil P by simple chemical tests [PDF]

open access: yes, 2008
The amounts of P extracted with acid ammonium acetate are significantly correlated with the bioavailable P reserves of Finnish soils. Together with clay percentage the simple extraction method is fairly reliable.

Effects of acid rain on competitive releases of Cd, Cu, and Zn from two natural soils and two contaminated soils in hunan, China [PDF]

open access: yes, 2007
Leaching experiments of rebuilt soil columns with two simulated acid rain solutions (pH 4.6– 3.8) were conducted for two natural soils and two artificial contaminated soils from Hunan, southcentralChina, to study effects of acid rain on competitive ...

Decreased DMI sensitivity of Plenodomus biglobosus (phoma of oilseed rape) associated with CYP51 substitution G476S

open access: yesPest Management Science, EarlyView.
Here, we report for the first time a target site mutation in the CYP51 gene of the oilseed rape phoma stem canker fungus Plenodomus biglobosus (Leptosphaeria biglobosa) that is associated with decreased sensitivity to sterol demethylation inhibitor fungicides.

Soil Bacterial and Fungal Community Composition in Top- and Subsoil From Irrigated Mediterranean Orchards

open access: yesSpanish Journal of Soil Science
The soil microbiome, crucial for nutrient cycling and soil health, has been extensively studied in topsoil, yet the subsoil microbiome remains relatively unexamined despite its potential contributions to agroecosystem functionality.

Global Fluoride Toxicology Landscape: Bibliometric Approaches and Scientific Mapping

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study analyzed research trends in the 100 most‐cited articles on fluoride toxicology, a topic widely debated due to the toxic effects associated with levels deemed safe for human exposure. A bibliometric analysis was conducted using the Web of Science‐Core Collection, extracting data such as citation count, authors, keywords, journal ...

Shifts in fungal communities drive soil profile nutrient cycling during grassland restoration

open access: yesmBio
Soil microbial diversity and community life strategies are crucial for nutrient cycling during vegetation restoration. Although the changes in topsoil microbial communities during restoration have been extensively studied, the structure, life strategies,

Higher subsoil carbon storage in species-rich than species-poor temperate forests

open access: yesEnvironmental Research Letters, 2014
Forest soils contribute ca. 70% to the global soil organic carbon (SOC) pool and thus are an important element of the global carbon cycle. Forests also harbour a large part of the global terrestrial biodiversity.
