Soil quality (SQ) can change due to management practices and the inherent properties of soil. Designed for enabling sustainability of agriculture, the objectives of this study are to (i) examine the roles of site-specific factors of Oxisols and Ultisols, (ii) determine the soil quality index of Oxisols and Ultisols in order to see the change in SQ due to management practices. Three varieties of corn, Local Kima, Sukma Raga, and Bisi-2 were grown in a multilocation experiment on a Typic Hapludox (CLTH), Plinthic Kandiudults (CLPK), and Plinthic Hapludoxs (CLPH) in Panyipatan Tanah Laut South Kalimantan Indonesia. The 17 attributes of soil sampled from 0 – 15 cm soil surface were statistically analyzed using the multivariate analysis of variance (manova) followed by principal factor analysis (PFA) of SAS 6.12 (SAS Inst. 1996). Combined with an expert system of the Soil Management Assessment Framework (SMAF), step by step data reductions of manova and anova(α < 0.05), followed by factor analysis was used to determined the amount of variance explained by each factor (eigenvalue > 1). The indicators included in the SQ equation are bulk density (BD), available water capacity (AWC), total organic carbon (TOC), soil pH, and soil P. The soils showed different relationships due to the difference of site-specific factors.Used the SMAF equation, it is found that the SQ index of CLTH, CLPK, and CLPH in Panyipatan are respectively 74.46, 69.47, and 54.00. |
