After adding protons to the solubilized organic materials, a dark solid precipitates that is commonly called ‘humic acid’. The organic matter that remains soluble after reacidification is ...

Agricultural practices such as tillage have resulted in the loss of humic material and soil organic matter. Consequently, there is an increased interest in the application of humic substances to ...

Artificial humic matter could compensate for what is lost in good soil quality due to a lack of circular economy such as sustainable crop rotations. Why? Natural humic substances are components of ...

Aiken and colleagues tested the role of a major soil organic matter compound, humic acid, for its ability to bind chronic wasting disease prions and impact infectivity. The researchers examined a ...

This method has shown that organic matter content in soils must be diluted to 2% to reduce backscattering and oversaturation of the detector in forested soils. In mineral horizons (A) there is ...

The researchers measured and compared the ratio of protein-like organic matter, which easily biologically decomposes, and humic-like substances, which hardly decompose, in both sea spray aerosols ...

Brownification is caused by increased leaching of terrestrial humic matter to aquatic ecosystems. Both these phenomena change lake phytoplankton community composition, and the proportion of EPA ...

Whereas the exudation of protein-like substances by healthy phytoplankton cells has been recognized, the in sity production of marine humic-like substances is still a matter of debate. Using axenic ...
