A research team reveals that the way plant residues transform into humic substances can profoundly reshape soil microbial ...

High temperature effects on soil humic substances were investigated both in natural and laboratory conditions. Differential Thermal Analysis and pyrolysis show that only temperatures above 250°C ...

Humic substances represent a crucial component of soil organic matter, playing an instrumental role in nutrient cycling, water retention and the enhancement of soil structure. Their complex and ...

Researchers have uncovered surprising links between natural humification processes in soil, carbon metabolism, and the spread of antibiotic resistance. The findings provide fresh insight into how ...

UVALDE – A recent study by Texas A&M AgriLife Research scientists at the Texas A&M AgriLife Research and Extension Center in Uvalde shows applying a soil amendment containing humic substances can ...

Researchers have described a process that suppresses the formation of methane in soils that are rich in humic substances. For this process to work, the soils need to switch between having no oxygen ...

Humic acid (HA) and fulvic acid (FA) extracted from fourteen surface soil samples (0-20 cms) belonging to nine major Soil Association Groups scattered over different agro-climatic situations, were ...

Disruption of natural methane-binding process may worsen climate change, scientists have suggested, painting a stark warning on the possible effects of gases such as methane -- which has a greenhouse ...

A cover-up is plainly involved; it’s not about scandal but dirt itself. That means soil, the upper layer of earth typically a few feet but sometimes 10 feet or more thick, usually black or dark brown.

This news release is available in German. Wetlands, including peatlands, have a high content of humic substances, which are organic compounds that form during incomplete decomposition of biomass.

The humic substances in these parts, which were charged by microorganisms in the absence of oxygen, then release the electrons to oxygen and thereby regenerate their capacity to accept electrons.
