Purpose Greenhouse gasses emission, depletion of nutrients and soil degradation are major factors that are deteriorating soil health. A global challenge to agriculture is the production of enough crops while reducing the impact of intensive chemical inputs on the environment. Humic acids (HA), a main fraction of humic substances produced through humification of organic matter, are considered as multi-functional biostimulants p...

The six phenoxyalkanoic acid herbicides currently used in the European Union have similar molecular structures. Therefore, we assumed the soil components involved in the adsorption mechanisms of these herbicides to be identical. The values of the adsorption distribution coefficient K d , obtained via batch experiments involving typical Polish Arenosol, Luvisol, and Chernozem profiles with a native pH of 4.2–7.7, were examined...

Humic substances, including humin fraction, play a key role in the fate of organic and inorganic xenobiotics contaminating the environment. Humin is an important fraction of humic substances, which has been the least studied to date. This is due to the difficulties connected with its isolation that pose a number of methodological problems. Methods of humin fraction isolation can be divided into following main groups: (1) diges...
