Comparative characterization of humic substances extracted from peat soils of gopalgonj and khulna regions of bangladesh
Humic substances act as a chelating agent for metal ion extraction. Soluble humic substances (HS) might be an alternative to use instead of synthetic chemicals such as mineral acid or EDTA. These natural extractants are less expensive, biodegradable, environment friendly, less destructive to soil structure and also improve soil properties. Two peat soils were collected one from Khulna University campus and another from Gopalganj basin. Humic substances were extracted from peat soils.
