QUANTITIES OF INDOLE-3-ACETIC ACID IN SECONDARY TRANSFORMD PEAT-MOORSH SOILS
The investigations of indole-3-acetic acid (IAA) were performed for three different peat-moorsh soils - Czarna Wies, Otoczne and Kwatera 17 located in the Biebrza River Valley in Poland. Each considered soils were utilized as meadow. Soil samples were taken from two depths: 5-10 cm and 50-80 cm. IAA, total organic carbon (TOC), dissolved organic carbon (DOC) in peat moorsh soils from these samples were analysed. The significant differences in the concentrations of IAA, TOC, and DOC between two investigated depths of among peat moorsh samples were observed. The measured concentrations of total organic carbon in the considered soils ranged from 37.2 to 45.6 %. Generally, the decrease of IAA, total organic carbon, however, increase of DOC concentration with depth of profiles was observed. The contents of dissolved organic carbon in the soils ranged from 5.3 to 19.4%. The quantities of IAA decreased simultaneously with TOC values and with the increasing depth of the soil profiles. The highest contents of IAA was determined in high layers of moorshes and ranged from 110,1 to 128,7 µg kg-1 dry mass. However the concentrations of IAA in deeper layers were lower and ranged from 69,3 to 87,1 µg kg-1 dry mass.
Keywords: Peat, chemical characteristics, organic carbon, dissolved organic carbon, indole-acetic acid.
