“…Based on field observations in 2019, or 4 years after replanting, the Ahorizon has been reformed with a looser structure and higher levels of organic materials than the B-horizon below it. This also demonstrates that replanting the area affected by mining was one of the attempts to restore the soil quality, especially in forming its essential element, organic materials (Cavalcante et al, 2019;Maiti & Ahirwal, 2018). The roots of the vegetation also help in the process of re-loosening the upper soil layer compressed by heavy mining equipment.…”

Volcanic rocks mining activity will undoubtedly remove vegetation cover and cause the physical environment changes. Revegetation effort as part of land rehabilitation program then often found many obstacles because it was mostly conducted without adequate knowledge of detailed morphology and soil characteristics at the post-mining area. This study investigates the geopedogenetic changes, including land surface morphology, recent geomorphic processes, and soil properties caused by andesite rocks exploitation at the northern flank of Mt. Ungaran, Central Java Province of Indonesia. A digital terrain model was firstly generated from small format aerial photography acquired by an unmanned aerial vehicle (UAV) to identify the surface morphology changes due to the mining. Soil observation on field and laboratory test were conducted from samples at the affected and unaffected mining areas in order to analyse the changes on pysiochemical properties. This research exhibits that the mining activities have altered a single convex hill into a complex land surface morphology consisting of sloping zone, basins and flat area. Human disturbance on pedogenetic process at the mining area are in the form of parent material alteration that make them return to the early stage of soil development and top soil reduction that modify its genetic horizons. In addition, the changes on surface morphology and the absence of vegetation cover right after the mining ends also triggered new geomorphic processes in the form of incision and deposition on slopes and basin respectively. The finer deposit layers then become a new parent material at the basin zone. Soil laboratory data demonstrate that the affected soils tend to have a high level of base saturation, but lower C-organic and N-total levels, which result in a less favourable environment for supporting vegetation growth. A precise surface morphology design, extra soil surface protection and organic matter enhancement could be wise recommendations for land managers to control soil incision and support vegetation growth at the andesite post-mining area.

“…Porous soil means that the soil has sufficient pore space to freely move water and air into or out of the soil (Hanafiah 2005). Thus, density and porosity are closely related to plant root systems where the growth action can break up dense layers, reduce soil density, and increase total soil porosity (Vogelmann et al 2012, Prevedello et al 2013, Cavalcante et al 2019.…”

Abstrak. Sifat fisika tanah merupakan salah satu sifat tanah yang menentukan kualitas suatu tanah serta salah satu penentu kesuburan tanah, serta berperan dalam pertumbuhan dan produksi tanaman, sehingga perlu ditentukan indeks kualitas fisika tanah. Penelitian ini bertujuan untuk mengetahui indeks kualitas fisika tanah (IKFT) pada tanaman kedelai berdasarkan perlakuan yang diberikan dan untuk mengetahui hubungan indeks kualitas fisik tanah dengan produktivitas kedelai. Lokasi penelitian ini berada di Kebun Percobaan Pacet, Kabupaten Cianjur, Provinsi Jawa Barat. Sifat fisik tanah yang digunakan untuk menentukan IKFT adalah tekstur, bulk density, porositas, pori drainase, air tersedia, permeabilitas, dan stabilitas agregat. Setiap parameter fisika tanah menggunakan skor dalam rentang 0 sampai 5. Penetapan IKFT pada lahan dapat menunjukkan berbagai kualitas sifat fisika tanah yang diwakili oleh beberapa sifat fisika tanah. Indeks kualitas fisika tanah (IKFT) pada masing-masing unit yang ditanami kedelai, yaitu berkisar antara 0,74-0,91 dengan kategori agak baik (P10) sebagai kontrol, baik (P1-P7 dan P9), dan sangat baik (P8). Indeks kualitas fisika tanah memiliki hubungan linier positif sedang antara IKFT dengan produktivitas kedelai (R = 0,4223) yang berarti semakin tinggi indeks kualitas fisika tanah maka produktivitas kedelai semakin tinggi.Kata kunci: sifat fisika tanah, indeks kualitas fisika tanah, tanaman kedelai Abstract. Soil physical properties are one of the soil properties that determine the quality of a soil as well as one of the determinants of soil fertility, as well as contributing to plant growth and production, so it is necessary to determine the physical quality index of the soil. This study aims to determine the soil physical quality index (SPQI) in soybean plants based on the treatment given and to determine the relationship between soil physical quality index and soybean productivity. This research location was at the Pacet Experimental Garden, Cianjur Regency, West Java Province. The physical properties of the soil used to determine the SPQI are texture, bulk density, porosity, drainage pores, available water, permeability, and aggregate stability. Each soil physics parameter uses a score in the range of 0 to 5. Determination of SPQI on land can show various qualities of soil physical properties which are represented by several soil physical properties. The soil physical quality index (SPQI) of each unit planted with soybeans, which ranged from 0.74-0.91 with categories slightly good (P10) as a control, good (P1-P7 and P9), and very good (P8). Soil physical quality index has a moderate positive linear relationship between SPQI and soybean productivity (R = 0.4223) which means that the higher the soil physical quality index, the higher the soybean productivity.Key word: soil physical properties, soil physical quality index, soybean plant

“…During the last few decades, a number of studies have focused on the removal of alkalinity and salinity in the residues prior to field rehabilitation. It has been increasingly recognized that for successful cover establishment on mine residues, the process of aggregate formation and soil development is critical (Cavalcante, de Castro, Chaves, da Silva, & de Oliveira, 2019). Soil aggregates are the basic unit of soil structure and aggregate stability affects the exchange of water, nutrients, gases and heat in soil, as well as the growth and metabolism of animals and microorganisms (Papadopoulos, Bird, Whitmore, & Mooney, 2009; Tang, Mo, Zhang, & Zhang, 2011; Yang, Liu, & Zhang, 2019).…”

Bauxite residue, a typical industrial solid waste which contains a large amount of Na+, is usually physically degraded. Understandings of aggregate formation, which is a critical process in soil development, are essential to facilitate ecological rehabilitation on the disposal areas. However, few studies have investigated the aggregation behaviour and mechanisms of key salt ions (Ca2+ and Na+) in residue aggregates. Therefore, an integrated method of Le Bissonnais' method, the combined determination method and laser diffraction measurements was applied to evaluate aggregate stability, surface properties and disintegration behaviour of bauxite residue following Ca/Na additions. With increasing Ca2+ addition, mean weight diameter increased, indicating improved resistance to dispersion. Ca2+ had a positive effect on flocculation of silt‐size microaggregates, while disintegration was induced following Na+ addition. Repeated laser diffraction analysis of residue samples circulating in 50 mmol L−1 electrolyte solution (Ca2+/Na+) provided a detailed view of the changes in particle size distribution as aggregates fragmented. The visualized three‐dimensional surface map revealed that Na+ promoted the disintegration of >250 μm aggregates into finer dispersed particles, while Ca2+ protected the microaggregates from fragmenting into smaller particles. Variation in electrochemical properties of aggregate surfaces affected the micro‐morphology significantly. The findings provide a new approach to specify pedogenic aggregate behavior of bauxite residue, while revealing the effects of Ca2+/Na+ on aggregate stability, surface electrochemical properties and its micromorphology. The results will provide a detailed understanding of aggregate behavior during soil formation process in bauxite residue.
