Physico-Chemical Characterization of Soil Samples from Bârlad Municipality
Keywords:
aqueous soil extract, acidity, alkalinity, heavy metal
Abstract
Soil quality is now thought of in a way that emphasises functionality in a broad context, involving soil not only as an environment for crop production but also as an important reservoir for water storage, as a buffer for filtering, transforming, and neutralising pollutants, and as a habitat for plants and animals. Some attributes (pH, soil conductivity, etc.) can be associated with several easily identified threats to soil quality, some of which are interrelated in the same way. For the present work, laboratory analyses were carried out to determine the physico-chemical parameters of soil from different areas. For soil quality analysis, the following parameters were determined: pH, conductivity, acidity, alkalinity, total nitrogen, aluminium, phosphates, iron, heavy metals, calcium, and magnesium content in the soil.
