The composition of organic matter (OM) was explained by effects of OM–cation interactions using polygalacturonic acid (PGA) as model substance. These effects were analyzed by COO− absorption bands in mid‐FTIR spectra. The change in intensity and wavenumber ranges of COO− bands in FTIR was quantified.

The German Soil Systematics and the Rationale Behind Its Revision
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Moss Biocrusts Regulate Heavy Metal Speciation and Mobility in Coal Mine Soils
ABSTRACT On a global scale, coal mining activities often lead to heavy metal(loid) contamination in soils of mine dump sites, posing serious ecological risks. As ecosystem “engineers,” biological soil crusts (biocrusts)—especially moss crust—have shown great potential in remediating heavy metal‐polluted soils, but their roles remain underexplored.

Soil Contamination Around the Copper Smelter and the Use of Soil Microarthropods as Bioindicators
ABSTRACT Soil contamination from smelter emissions, including heavy metals (HM), rare earth elements (REEs), and sulfur, poses a significant threat to soil ecosystems. In the immediate vicinity of the Głogów Copper Smelter, HM concentrations were several times higher than in more distant forest stands.

Characterization of Humic Acids from Raised Bog Peat
Humic substances form most of the organic component of soil, peat and natural waters, but their structure and properties very much differs depending on their source.

ABSTRACT The positive effect of multisource nitrogen fertilization strategies on improving soil fertility and crop yield in saline‐alkali soil has been evaluated. However, the responses of soil quality and ecosystem functions to multisource nitrogen fertilization strategies, and their roles in regulating maize yields in saline‐alkali soils remain ...

ABSTRACT Cadmium (Cd) contamination in paddy fields poses a high potential risk of environmental exposure. Organic fertilizer application can promote the efflux of rice root exudates, increase soil organic matter, and induce changes in Cd activity in rice fields.

ABSTRACT Tea plantations represent significant carbon (C) sinks in agricultural landscapes, yet how variety‐specific organic inputs are associated with the molecular composition and stability of soil organic carbon (SOC) within aggregate hierarchies remains unclear.
