Comparing Soil Chemical and Biological Properties in Varied Land Use

초록

Soil chemical and biological properties can be varied depending on different land use. In particular, soilbiological properties could be highly influenced by soil chemical properties. Therefore, main objective of thisresearch was to compare soil chemical and biological properties in different land use and examine acorrelation between soil chemical and biological properties. A total of 400 soil samples that evenly distributedfrom forest (FS), agriculture (AS), urban (US) and remediated (RS) area was collected. Soil chemicalproperties; pH, EC, soil organic matter (SOM), available phosphorus (AP), and cation exchange capacity(CEC) and biological properties: soil respiration (SR) and soil enzymes such as dehydrogenase (DHA), β-glucosidase (GLU), phosphatase (PHA), aryl-sulfatase (ARS), and urease (URE) were evaluated. Resultshowed that all soil chemical properties were within the optimum range of each land use. Among different soilchemical properties, SOM and AP were the most significantly different depending on varied land use. In caseof soil biological the order of all enzyme activities from the highest to the lowest was FS > AS > US > RS andsoil organic matter (p < 0.01) was a main factor affecting soil microbial activity. Overall, SOM managementcan be the most important to enhance soil microbial activity leading to improvement of soil health.
