Nature of Plant Components Identified in Soil Humic Acids
INTRODUCTION The origin of the humic acid fraction of soils is still unclear in spite of extensive investigations accomplished over the last years (ref. 1). Different origins have been proposed, based on the most recent theory or on the applica tion of the latest analytical method. Thus, it has been proposed that soil humic acids are derived from lignins, microbial activity and synthesis of me...
متن کاملPartial characterization of soil humic acids through biodegradation.
A strain of Pewicillizi?tz freqzientans was successfully employed for partial degradation and characterization of humic acids. Salicyl alcohol and salicylalclehyde were detected i n culture filtrates of the fungus ~rtilizing humates under reduced oxygen tension. The enzyme systems iiivolved in the degradation of humic acids were adaptive. The humate-adapted lnyceliirln was capable of metabolizi...
متن کاملTetracycline sorption to coal and soil humic acids: an examination of humic structural heterogeneity.
The sorption properties of tetracycline were compared between a coal humic acid (CHA) and a soil humic acid (SHA) under various solution chemistry conditions. Structural characteristics of the two humic acids were quantified in detail by elemental analysis, solid-state (13)C nuclear magnetic resonance (NMR), acid-base titration, and Zeta potential measurement. The CHA consists primarily of poly...
متن کاملEffects of humic acids from vermicomposts on plant growth
The interactions between earthworms and microorganisms can produce significant quantities of plant growth hormones and humic acids which act as plant regulators. Experiments were designed to evaluate the effects of humic acids extracted from vermicompost and compare them with the action of commercial humic acid in combination with a commercial plant growth hormone, indole acetic acid (IAA) whic...
متن کاملSoil humic acids may favour the persistence of hexavalent chromium in soil.
The interaction between hexavalent chromium Cr(VI), as K(2)CrO(4), and standard humic acids (HAs) in bulk solution was studied using three complementary analytical methods: UV-Visible spectroscopy, X-ray absorption spectroscopy and differential pulse stripping voltammetry. The observed UV-Vis and X-ray absorption spectra showed that, under our experimental conditions, HAs did not induce reducti...
