Spectroscopic Properties of Humic Substances in Permanent Grassland Soil
Popis výsledku v původním jazyce
UV-VIS and infrared spectroscopy (FTIR) were used for humic substances quality evaluation. Both methods are widely applied because of their availability, sensitivity, rapidity, and affordability. The calculated spectral indexes assess the stability, hydrophobicity, and content of different functional groups in humic substances' molecules. Humic substances and humic acids were isolated from Gleyic Fluvisol (locality Jaroměřice, Czech Republic). The soil is under permanent grassland, with intensive management (4 cuts/year) and fertilisation with high-quality farmyard manure (FYM - the cattle loading 2 DJ. ha-1). Soil samples were taken from a depth of 0-0.15 m from control and FYM variants during 2023-2024. Results were statistically evaluated (EDA, ANOVA /Tuckey's test/). UV-VIS spectra indicated a higher total humic substances content after amending soil with FYM. FTIR spectra showed more aliphatic and hydrophilic components after FYM amendments. Linear correlation was found between humic acid content and organic carbon content.
