Abstract

In the Philippines, legacy mines and active mine wastes pose potential threats since these may contain elevated concentrations of potentially toxic elements (PTEs) and high natural radioactivity. In this study, legacy mine wastes from the Philippine Iron Mine (PIM), Barlo Mine (BM), and Rapu-Rapu Mine (RRM) and active mine tailing from Padcal Mine (PM) were analyzed to determine the concentrations of fifteen (15) PTEs and the activity concentrations of natural radionuclides. Several quantitative risk indicators and radiological health risk parameters were utilized to determine the potential effects of these mine wastes to the natural environment and to human health. Legacy mine wastes have higher contents of PTEs and are more polluted by PTEs than PM tailing. Both enrichment factor (EF) and geoaccumulation index (Igeo) values suggest that legacy mine wastes are strongly polluted by As, Cd, Cu, and Mo. BM and RM wastes are also polluted by Pb, Sb, and Zn; PIM waste is polluted by Ni and V; and BM waste is polluted by Tl. Padcal mine tailing is only moderately polluted by Cu and Mo. The natural radionuclide activity concentrations of legacy and active mine wastes are below the global background values and the radiological hazard indices are also all lower than their permissible limits, except for 40K, 238U, and absorbed gamma dose rate in PIM due to a geogenic source. Unlike the PTEs, radioactivity in the legacy and active mine wastes are not enhanced by mining activities and is not a significant risk factor to human health.

Abstract

Land use affects changes in peak discharge so that it has the potential to cause or prevent flooding. Sago has morphological characteristics that have the potential to absorb more water. This study aimed to determine the magnitude of the change in peak discharge in the upstream watershed after sago planting. Observations were made on the three growth phases of sago palms (initial, middle, and mature phases). The research stages included calculating the runoff coefficient value under sago stands at three growth phases. Peak discharge of the existing conditions (settlements, rice fields, mixed gardens, shrubs, sand dunes, forests, and water bodies) was estimated after three scenarios of sago land use. The scenarios consisted of 25% of the land area planted with sago (scenario 1), 50% for scenario 2, and 100% for scenario 3. The data were analyzed quantitatively by comparing peak discharge in the existing conditions with scenario results. The results showed that the peak discharge in the existing conditions was 52.36 m3 hour-1. Peak discharge in the initial phase of scenario 1 was 18.94 m3 hour-1, scenario 2 was 37.88 m3 hour-1, and scenario 3 was 75.77 m3 hour-1. Peak discharge in the middle phase of scenario 1 was 19.01 m3 hour-1, scenario 2 was 38.02 m3 hour-1, and scenario 3 was 76.04 m3 hour-1. Peak discharge in the mature phase of scenario 1 was 6.38 m3 hour, scenario 2 was 12.76 m3 hour-1, and scenario 3 was 26.55 m3 hour-1. The peak discharge in the upstream watershed decreased after the scenarios with the use of sago land for all growth phases, except for scenario 3 of the initial and middle phases.

Abstract

The inorganic fertilizer that is used excessively in tea plantations causes soil health degradation. Tea pruning residue and tea fluff are local biomass that has the potential to be used as alternatives to soil nutrient input that is not well conducted in the tea plantation. This study evaluated biochar from the residue of tea pruning and tea fluff compost as potential organic materials to improve the chemical properties of soil in tea plantations. The tea pruning residue biochar and tea fluff compost were mixed in Inceptisols in a pot experiment with treatment combinations of A = control, B = 2.5 t manure compost/ha, C= 0.25% biochar + 1 t tea fluff compost/ha, D = 0.50% biochar + 1 t tea fluff compost/ha, E= 0.75% biochar + 1 t tea fluff compost /ha, F = 0.25% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, G = 0.50% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, and H = 0.75% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha. Soil incubation was conducted for 90 days, and soil samples were analyzed for pH, organic C, available P, exchangeable Mg, and exchangeable K contents. The results showed that the mixture of 0.50% biochar + 1 t tea fluff compost /ha + 2.5 t manure compost/ha gave the most optimal improvement in soil properties. The improvement percentages of soil properties obtained were available P of 334%, Exchangeable Mg of 38%, exchangeable K of 244% and pH of 4.6.

Abstract

The study aimed to evaluate the effect of area exclosure established in a degraded area with moisture harvesting structures (EX-SWC) relative to the adjacent exclosure area without moisture harvesting structures (EX) in restoring the woody plants. Vegetation data from a total of 30 plots that has an area of 20 m x 20 m, in the EX-SWC and the adjacent EX area were collected, independently. The density of trees and seedlings, diversity, vegetation structure and Importance Value Index (IVI) were analysed. Pearson’s correlation was also used for the data analysis. The Shannon diversity index was 1.6 and 1.57 in the EX-SWC and EX area, respectively. The relative density of trees (578 stems/ha) and seedlings (1530 stems/ha) in the EX-SWC area were relatively higher than the relative density of trees (466 stems/ha) and seedlings (1202 stems/ha) in the adjacent EX area. There was no significant relationship between the number of moisture harvesting structures established in each plot and the relative density of seedlings per plot (p <0.05, R2=0.18). The relative density of seedlings at the lower height classes (1 – 60 cm) in the EX-SWC area was relatively higher than the adjacent EX area. The IVI result for most of the recorded species in the EX-SWC area was also relatively higher than in the EX area. The overall results showed that the implemented moisture harvesting structures facilitated the regeneration of woody plants in the degraded area. Therefore, we recommend implementing soil and water conservation structures in degraded area restoration projects to facilitate the regeneration of woody plants.

Abstract

Abiotic stress is a limiting factor for plant growth and development. The use of arbuscular mycorrhizal fungi can reduce the negative effects of abiotic stress. This study aimed to determine the tolerance of Nauclea orientalis inoculated with mycorrhizae to drought and waterlogging stresses. This research was carried out at the Indonesian Mycorrhizal Association’s greenhouse and Forestry laboratory University of Halu Oleo in Kendari City, Southeast Sulawesi Province, Indonesia, from March to June 2019. The study used a factorial completely randomized design consisting of two factors. The first factor was Arbuscular Mycorrhizal Fungi (AMF) inoculations (A) consisting of a control, AMF types of Acaulospora sp.-1, and Claroideoglomus etunicatum.  The secod factor was environmental stress treatments (B) consisting of a control, soil moisture 25% of field capacity, 50% of field capacity, inundated as high the polybag (9 cm high) and inundated over the polybag. The results showed that local AMF was effective in improving plant growth. Interaction between inoculation of Acaulospora sp.-1 and environmental stress significantly increased AMF colonization on the N. orientalis roots. Inoculation of C.etunicatum significantly improved the N. orientalis growth. The treatment of drought stress with a field of 50% field capacity negatively influenced plant dry weight and the relative growth of the N. orientalis.

Abstract

Changes in natural land use for monoculture cropping systems may affect the soil properties over a certain period of time. In an attempt to evaluate soil chemical properties in the cassava cropping system, the research was conducted in Pati Regency, Central Java. Four land use systems were compared, i.e. monoculture cassava (cultivated for 5, 10, and 15 years) and agroforestry systems in two different slopes (i.e., 8-15% and 16-40%), with four replications. Soil samples from each location were taken at a depth of 0-20 and 21-40 cm for soil chemical analysis (pH, cation exchange capacity, organic C, total N, available P, exchangeable K, Ca, and Mg). Soils in agroforestry systems had higher pH, CEC, the content of organic C, total N, exchangeable K, Ca and Mg than in cassava cropping systems, especially on the slope of 8-15%. The soil under 15 years cassava and on the slope of 16-40% had the most degraded soil chemical properties, as reflected by the lowest content of organic C, total N, exchangeable K, and slightly lower CEC and the content of exchangeable Ca and Mg. Soil chemical properties on the slopes of 8-15% were significantly better than on the slopes of 16-40%, especially in CEC and the content of organic C, total N, exchangeable K and Mg. However, there was an unclear pattern of the available P content, which was possibly due to the application of P fertilizer in cassava cropping systems.

Abstract

Acid dry land can become a centre for soybean production through improved cultivation techniques and the use of improved varieties that are acid-tolerant. In connection with this problem, research has been carried out to evaluate the effect of the application of organic fertilizers, inorganic fertilizers, and biological fertilizers on soybean productivity in acid soils. The experiment was conducted in a screen house at Iletri, Malang, East Java, using acid dry soil from Banten, West Java. The soybean seed used in this research was Wilis variety. The evaluated treatments were a combination of types and quantities of nutrient-rich organic fertilizer with acid formula (Santap-M), NPKS Phonska inorganic fertilizer, and biological fertilizer (Iletrisoy Rhizobium and Pseudomonas sp P-solubilizing bacteria, both were Iletri collections). The results showed that the addition of organic and inorganic NPKS fertilizers on acid soils could increase soybean productivity and the population of P-solubilizing bacteria Pseudomonas sp. The recommended alternative technology component for improving soybean productivity and Banten acid soil is a combination of 1500 kg Santap-M nutrient-rich organic fertilizer + 150 kg Phonska/ha. The results of this study add to the positive list that use of organic fertilizers and inorganic fertilizers NPKS is an alternative option that needs to be considered for sustainable soybean cultivation in acid dry land.

Abstract

This study assessed organic matter,  N, P, and K contents in three soil types after the application of biochars and organic fertilizers for two years. The experiment was arranged in a nested design with two factors. Three types of biochar and two types of organic fertilizer were used singly or in combination on three soil types. Among the treatments, the application of tobacco processing waste biochar on Inceptisol and rice husk biochar plus manure on Entisol resulted in the highest soil organic matter and total nitrogen contents. The highest phosphorus content was observed from rice husk biochar treatment on Inceptisol and from rice husk biochar+manure treatment on Entisol and Litosol. The highest K content in Inceptisol and Litosol occurred with each biochar treated rice husk biochar+manure treatment. The highest K content in Inceptisol and Litosol was observed in each tobacco waste biochar+compost treatment and in compost treatment only, respectively.

Abstract

Limestone processing produces dust covering the soil around the quarry site and may affect soil fertility. Post-mining activities in a forest area are mandatory to restore biodiversity, such as tree species of non-wood products. This study aimed to determine the impact of limestone dust on soil and measure the effectiveness of soil treatment for revegetation. This study employed a randomized block design with three soil groups, i.e. uncovered with limestone dust, covered with 2.5 cm limestone dust, and covered with 5 cm limestone dust. Each group had five replications and was treated with poultry manure (0 kg m-2, 5 kg m-2, 10 kg m-2, and 15 kg m-2) and 2 L of 1% (v/v) humic acid. The amendment of manure and humic acid increased the soil organic C, total N, C/N ratio, and exchangeable K but increased the soil available P content. The soil respiration and total bacteria increased along with the thinning of the limestone dust. Overall, the treatments significantly affected pH, C/N ratio, exchangeable K, and electrical conductivity. At the same time, the group significantly affected organic C, total N, C/N ratio, exchangeable K, electrical conductivity, cation exchange capacity, bulk density, total bacteria, and clay. Based on land suitability assessment guidelines, the soil required nutrient improvement and pH reduction to grow proper non-wood products tree species.

Abstract

The study aimed to determine the areas of future urban expansion in Bordj Bou Arreridj, Algeria, by using multi-criteria analysis for decision-making. First, the future population was estimated to calculate the area we would need for the horizon of 2041AD. Second, criteria that contribute to determining the best areas for future expansion were selected based on recent research literature. Six factors were adopted: (industrial areas, agricultural lands, urban areas, road network, slopes, and hydrographic network). Third, the analytic hierarchy process (AHP) was used to make a comparison of the previous standards and to extract the weights. Fourth, translating the results obtained in the (QGIS) program and extracting a digital map showing areas suitable for future urban expansion according to three classifications (high spatial suitability, acceptable, and low). The results showed that the areas with high spatial suitability it densely distributed in the northeastern and western directions with an area of 12.42 km² or 23%. It is considered an insufficient area to meet the future need of 2041 AD, which amounted to 14.20 km². Followed by areas with acceptable suitability distributed in four geographical directions, occupying an area of 15.67 km² or 35%, which is a sufficient area and can be placed as a balance to fill the deficit. While the areas with low suitability densely distributed in the east-west sides, with an area of 16.26 km² or 37%. The research proved that the integration between (AHP) and (GIS) technologies have an important role in helping decision-makers identify suitable areas for future expansion, reduce the problems of random urbanization and create a homogeneous sustainable environment. Urban development in the future.
