Abstract

An understanding on relationship between water content and mineralization of carbon (C) and nitrogen (N) across soils varying in physical and chemical characteristics is required to assess the influence of soil physico-chemical properties on soil organic matter decomposition. However, such information is rarely available. Relationship between C and N mineralization of three soils varying in physico-chemical properties with different measurements of water content (water-filled pore space, gravimetric water content, volumetric water content, and water holding capacity) was studied through an incubation experiment for 8 weeks. Results of the experiment showed that C and N mineralization increased with increasing water content, reached a maximum, and then decreased with subsequent increasing water content levels. Maximum C and N mineralizations were observed at 70-80% and 50% water-filled pore space (WFPS),  respectively. The ranges of WFPS for C and N mineralization were the narrowest among other measurements of water content. Therefore, it was likely that a single WFPS could be used in subsequent incubations to examine either C or N  mineralization of soils with different characteristics. Result of this study suggests that the preliminary experiment on the   relationship between mineralization of C and N and water content is necessary to do where mineralization is needed to be assessed in soils that have different physico-chemical  characteristics.Keywords: Carbon and nitrogen mineralization, percent of water-filled pore space, water content[How to Cite : Saidy AR. 2013.

Abstract

Relationship Between Concentration of Cr(VI) and Soil Chemical Characteristics: Preliminary Information for Remediation of Ex-mined Lands in the South Kalimantan (A.R. Saidy and Badruzsaufari): High concentration of heavy metals is frequently observed as an effect of mining activity. In order to determine relationship between concentration of Cr(VI) in ex-mined land and soil chemical characteristics, 15 of soils were sampled from ex-coal and chromate mined-lands in the South Kalimantan Province. Result of the experiment revealed that soils from the ex-mined lands contained 700 - 2645 mg Cr kg-1 soil. This research also showed that 0,73-1,35% of total Cr in these soils exist in the form of hexavalent chromium (Cr(VI)) that is toxic and carcinogen. Concentration of Cr(VI) in these soils were correlated significantly with soil pH in which increasing soil pH would lead to increase in concentration of Cr(VI). In addition, increasing in soil organic carbon will be followed by decreasing concentration of Cr(VI). Relationship between concentration of Cr(VI) and soil pH and organic carbon content could be useful for preliminary information for Cr reclamation of ex-mined lands.
