Evaluation of the physical quality of soil on coal mine reclaimed land is needed to monitor and evaluate reclamation activities aimed at restoring and improving soil quality. The results of the evaluation of the quality of the physical properties of the soil are presented as an index of the physical quality of the soil which can be used as input for taking further soil management actions. This research aims to determine the characteristics of the physical properties of the soil and assess the physical quality of the soil on coal mine reclaimed land as outlined in the soil physical quality index (IKFT). This research was carried out from August to November 2022 on the reclaimed coal mine land of PT. Sumber Bara Abadi, Sumber Sari Village, Sebulu District, Kutai Kartanegara Regency, East Kalimantan, Indonesia. The method used in this research was a survey. Determining the location of soil samples was carried out using a purposive method based on reclaimed land cover, reclamation age, and slope. Data analysis was carried out directly in the field and soil analysis in the soil laboratory of the Faculty of Agriculture, Mulawarman University. The assessment of the IKFT is carried out after the analysis of the physical characteristics of the soil has been determined. The IKFT is measured by following a three-step procedure, namely identification of indicator data sets, interpretation of indicators, and integration of all indicator scores into one overall IKFT value. The research results show that (1) the physical characteristics of the soil are: soil texture varies between clay, clay loam, and sandy clay loam; Soil porosity is classified as poor and good; stability of aggregate is classified as less stable aggregate to very stable; Soil permeability is relatively slow and moderate; bulk density is classified as medium and slightly dense; surface rocks are abundant; the depth of the solum is classified as shallow and medium; and (2) the physical quality of the soil on reclaimed coal mine land is classified as rather low and moderate with limiting factors including a large amount of surface rock, large bulk density, low solum depth, and low aggregate stability.

“…The bulk density (BD), soil water content (SWC), and porosity were determined using the undisturbed soil sample cores using Kopecky's cylinder method (Piaszczyk et al, 2020;Grzywna and Ciosmak, 2021). We first recorded the weight of the empty cylindrical soil auger with a volume of 100 cm 3 (m 0 ).…”

Vegetation succession can change the function and quality of the soil. Exploring the changes in soil properties during secondary forest restoration is of great significance to promote forest restoration and improve the ecological service function of subtropical ecosystems in South China. In this study, we chose three typical forests in subtropical China as restoration sequences, broadleaf–conifer mixed forest (EF), broad-leaved forest (MF), and old-growth forest (LF), to study the changes in soil physico-chemical and biological properties and the changes of soil comprehensive quality during the secondary succession of subtropical forest. The results showed that the soil physical structure was optimized with the progress of forest succession. The soil bulk density decreased gradually with the progress of forest restoration, which was significantly affected by soil organic carbon (p < 0.01). In LF, the soil moisture increased significantly (p < 0.05), and its value can reach 47.85 ± 1.93%, which is consistent with the change of soil porosity. With the recovery process, soil nutrients gradually accumulated. Except for total phosphorus (TP), there was obvious surface enrichment of soil nutrients. Soil organic carbon (15.43 ± 2.28 g/kg), total nitrogen (1.08 ± 0.12 g/kg), and total phosphorus (0.43 ± 0.03 g/kg) in LF were significantly higher than those in EF (p < 0.05). The soil available nutrients, that is, soil available phosphorus and available potassium decreased significantly in LF (p < 0.05). In LF, more canopy interception weakened the P limitation caused by atmospheric acid deposition, so that the soil C:P (37.68 ± 4.76) and N:P (2.49 ± 0.24) in LF were significantly lower than those in EF (p < 0.05). Affected by TP and moisture, microbial biomass C and microbial biomass N increased significantly in LF, and the mean values were 830.34 ± 30.34 mg/kg and 46.60 ± 2.27 mg/kg, respectively. Further analysis showed that total soil porosity (TSP) and TP (weighted value of 0.61) contributed the most to the final soil quality index (SQI). With the forest restoration, the SQI gradually increased, especially in LF the value of SQI was up to 0.84, which was significantly higher than that in EF and MF (p < 0.05). This result is of great significance to understanding the process of restoration of subtropical forests and improving the management scheme of subtropical secondary forests.

Physical properties of soil are good for plant growth is closely related to the management of the soil, so it will need to integrate of physical properties to get an overall assessment with making soil physical quality index (SPQI). This study aims to an evaluation of physical properties and determines the physical quality index using several unit treatments to produce various physical qualities on Groundnut/Arachis hypogeal L. The location of the research was carried out in a farmer's garden in Cimaung Village, Cikeusal District, Serang Regency, Banten Province (Coordinates 6o12’14’’ S dan 106o11’52’’E). To analyze the SPQI using several physical properties of the soil such as texture, bulk density, porosity, permeability, and aggregate stability. Each indicator has a scoring parameter to assess the soil physical quality index with a score range of 0-5. An assessment SPQI in a land unit is able to describe the various physical qualities of the soil which are represented by several physical properties of the soil. The unit treatment which class categorization of soil physical quality index indicated slightly good (U2), medium (U1, U3-U6), and slightly poor (U7) as a control.
