Summary: The investigation of the mechanisms organic matter transformation in compost organic fertilizers is an urgent task of modern soil ecology and soil chemistry. The study found that the mechanism of converting newly formed humic acids (HAs) into more resistant forms varies depending on whether calcium carbonate or biochar is present. Calcium carbonate causes a physicochemical rearrangement of newly formed HAs, while biochar intensifies humification processes and increases the degree of aromatization. Understanding the formation and transformation mechanisms of HAs at the early stages of humification can help optimize methods for obtaining organic fertilizers.

Summary: The study found that CaEDTA remediation significantly decreased the free fraction of humic acids in soils contaminated with potentially toxic metals, while the bound fraction of humic acids and fulvic acids remained unchanged. Disturbance of intermolecular bonds during remediation affected the composition of the free humic acid fraction, confirming a selective removal of non-radical molecules such as carbohydrates while increasing the concentration of free radicals in acidic soil. The restoration of free humic fractions is likely to be a long-term process, indicating that CaEDTA soil washing is moderately conservative in terms of soil organic matter remediation.

Summary: The changes in quantitative and qualitative humus parameters in loamy sand with the addition of poultry litter (PL) and poultry litter biochar (PLB) were estimated over a 5-year study period. It was found that PL had a significant impact on the mineralization of organic matter and caused noticeable changes in humus compounds. On the other hand, PLB had a slower mineralization rate, especially at higher doses, and had a more favorable effect on the structure and mobility of humic acid carbon compared to PL.

Summary: This research assessed the potential of soil amelioration and produced digital maps of soil properties for arable plot planning and irrigation system operation. The study found that the soil in the area had high organic carbon content, neutral acidity, and sufficient nitrogen and potassium concentrations without exceeding permissible levels for heavy metals. The spatial distribution of soil properties was non-homogeneous, and remote sensing covariates played a critical role in explaining their variability. These findings are valuable for developing reclamation strategies for similar soils and improving crop productivity.
