Abstract

The widespread use of glyphosate to eradicate weeds in agricultural areas has the potential for contamination and residues in the soil that must be carefully considered. This study aimed to elucidate the effect of glyphosate contamination on the chemical properties of an Inceptisol ameliorated with sub-bituminous coal. This study used a completely randomized design with three treatments and three replications, namely A = control (soil with no glyphosate and sub-bituminous coal), B = 5 kg soil + 100 mg glyphosate L-1, and C = 5 kg soil + 40 t sub-bituminous coal ha-1 + 100 mg glyphosate L-1. The results showed that glyphosate contamination significantly affected pH, electrical conductivity (EC), mineral and organic matter (OM) composition, cation exchange capacity (CEC), organic carbon (OC), total N, and available P of an Inceptisol ameliorated with sub-bituminous coal. The application of 40 t sub-bituminous coal ha-1 as an alternative ameliorant improved pH H2O by 0.30, EC by 0.05 dS m-1, OM by 1.03%, CEC by 18.08 cmol(+) kg-1,  OC by 1.16%,  total N by 0.20% and available P by 5.47 ppm of the soil compared to the control. The residual glyphosate concentration in the soil ameliorated with sub-bituminous coal was 0.04 mg kg-1 compared to the initial glyphosate concentration of 100 mg L-1. The correlation between glyphosate residue had no significant relationship with the chemical properties of an Inceptisol ameliorated with sub-bituminous coal.

Abstract

The implementation of degraded land rehabilitation programs and community-based forest management certification is widely recognised to enhance the status of wono land cover and aid in climate change mitigation. The expansion of the restoration efforts can be monitored using satellite images to track the progress of operations by observing changes in land cover area. Community forest certification also can enhance the success of land restoration endeavours. Therefore, this study aimed to show the change in forest land cover and the amount of carbon stored from 1972 to 2021. Landsat imagery was used to depict land cover conditions in 1972, 1982, 1993, 2000, 2008, 2014, and 2021, before and after the implementation of restoration and community forest certification programs. The Normalized Difference Vegetation Index approach was employed for satellite images captured in 1972 and 1982, while the Forest Canopy Density method was employed for images in 1993, 2000, 2008, 2014, and 2021, to illustrate the progressive increase in wono land cover. Meanwhile, carbon storage was analysed from 1972 to 2021 using national carbon storage conversion. The results indicated that restoration activity and the establishment of community forest certification increased wono area and carbon storage, which totalled 55.90 ha and 5,499.04 t C between 1972 and 2021. Augmenting carbon storage within wono land cover constituted an effective strategy for mitigating climate change.

Abstract

One of the efforts to manage the risk of ground movement is to identify landslide-prone area characteristics. This study aimed to investigate the geophysical, geotechnical, and vegetation characteristics of landslide and non-landslide areas. This study adopted the resistivity geoelectric method to identify the type and structure of subsurface materials in landslide and non-landslide regions in Pujon and Ngantang, Malang Regency. Measurements in this study were done in four locations. Each geoelectric measurement path at each location was determined to be 100 m long. The electrodes were spaced apart by 10 m for measurements between the current electrode and the potential electrode. The dipole-dipole configuration of the geoelectric survey trajectory is determined based on the former landslide event to predict underground material. In addition, an investigation of geological, geotechnical, and vegetation characteristics was carried out. The results showed that the geophysical, soil, and vegetation characteristics of the landslide and non-landslide slopes were similar. The geophysical characteristics of the soil in all study locations indicate the presence of a slipping surface, which makes the land prone to landslides. The slipping plane was formed due to differences in the types of rocks between the surface and deep layers. The existence of vegetation has an important role in landslide management. Non-landslide areas tended to have denser tree vegetation and a higher number of shrub species.

Abstract

The low fertility of post-brick mining soil may be improved by applying biochar to the soil because biochar is an excellent soil amendment, although its quality varies depending on the raw materials used. Therefore, soil fertility, nutrient availability, and crop yields are affected by the type and amount of biochar added to soils. This study examined the effect of types and dosages of biochar on nitrogen, phosphorus, and potassium availability of post-brick mining soil to increase maize yield. The treatment combinations of biochar dosages (0 t ha-1, 15 t ha-1, 30 t ha-1, and 45 t ha-1) and biochar types (coconut shell, wood, and rice husk biochars) were arranged in randomized block design with three replications. Each treatment plot measuring 4 m x 4.5 m was planted with maize seeds with a planting space of 80 cm x 25 cm. Urea (135 kg N ha-1), SP36 (36 kg P2O5 ha-1), and KCl (110 kg K2O ha-1) were applied as basal fertilizers. The results showed that at eight weeks after biochar application, the amount and type of biochar positively affected maize yield. The application of rice-husk biochar at 30 t ha-1 resulted in the highest maize yield. The application of each type of biochar at 45 t ha-1 yielded the highest increase in the availability of nitrogen, phosphorus, and potassium in the soil.

Abstract

This study aimed to locate areas along the Debretabor-Alember route segment in northern Ethiopia that are susceptible to landslides. Geospatial tools, specifically frequency ratios (FR) and information values (IV), were used to develop landslide susceptibility maps (LSMs). A comprehensive on-site investigation and analysis of Google Earth imagery were conducted, resulting in the detection and analysis of 89 landslides, including current and historical events. The dataset used for validation comprised 78% of the previously documented landslides, whereas the remaining 22% was used for training. Several factors were considered in this study to determine landslide susceptibility, including "slope, aspect, curvature, elevation, lithology, distance from streams, land use and cover, precipitation, normalized difference vegetation index (NDVI)", and the FR and IV models. Based on the results obtained using the FR approach, specific areas exhibited different levels of susceptibility, ranging from very low to moderately high, medium, high, and very high. These areas covered a total of 18.4 km2 (19.9%), 18.9 km2 (20.5%), 19.7 km2 (20.3%), 17.7 km2 (20%), and 17.7 km2 (19%), respectively. The LSMs generated by the IV model indicated multiple susceptibility classes in the study area, varying from very low to very high. These maps revealed that 18.4 km2 (19.8%), 18.8 km2 (20%), 18.9 km2 (19.5%), 18.8 km2 (20.5%), and 18.3 km2 (19.8%) of the area fell into these susceptibility classes. The landslide density indicator method was employed to validate the LSMs. The FR and IV models demonstrated that a significant proportion of confirmed past and current landslide records (72.16% and 73.86%, respectively) occurred in regions with a high or very high susceptibility to landslides. Overall, the IV model, which utilized latent variable structural modeling (LSM) in the independent variable model, outperformed the fixed effects regression model (FR).

Abstract

Planning, managing, and developing sustainably all depend on mapping and monitoring changes in land use and land cover (LULC) in Phu Tho Province, Vietnam. In this study, remote sensing and geographic information system (GIS) techniques were employed to track LULC changes in the study area from 1992 to 2022. The supervised classification method in ArcGIS 10.8 software was applied to Landsat satellite data (Landsat 5-TM for 1992 and 2010, and Landsat 9-OLI/TIRS for 2022) to detect and classify five main LULC classes: agricultural land, barren land, vegetation, built-up, and waterbodies. The accuracy of the classification was assessed using kappa coefficients, which were found to be 0.882, 0.891, and 0.915 for the years 1992, 2010, and 2022, respectively. During the period 1992-2022, the areas of agricultural land, built-up, and waterbodies increased by 148.84 km2, 304.15 km2, and 41.04 km2, respectively. However, the areas of barren land and vegetation decreased by 289.39 km2 and 204.64 km2, respectively. Furthermore, the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) were utilized to rapidly assess changes in LULC, and their trends were found to be consistent with the supervised classification results. These changes in LULC pose a significant threat to the environment, and the findings of this study can serve as a valuable resource for future land use planning and management in the area.

Abstract

The application of lime is the general method of improving acid sulfate soils. However, if a lot of lime is applied, it can reduce the bioavailability of nutrients in the soil, especially phosphorus. The objective of this study was to investigate the effects of liming at different rates on the availability, adsorption, and desorption of phosphorus in two post-active acid sulfate soils (Ay and Se). The experiment was performed in the laboratory. The experiment was laid out in a completely randomized design (CRD) with four treatments and three replicates, i.e., the application of lime at a rate of 0 (control), 0.5, 1.0, and 2.0 times the lime requirement (LR). The lime requirements of the soils in the Ay and Se were 5,690 and 12,250 kg CaCO3/ha, respectively. The finding revealed that increasing the amount of lime could increase soil pH, available phosphorus, and the phosphorus activation coefficient. Application of lime at a dosage of 1.0-2.0 LR resulted in the highest phosphorus adsorption maximum (Qm) (380 mg/kg), while 0.5 LR resulted in the lowest Qm (353 mg/kg) in Se soil only. As lime dosage increased, phosphorus desorption maximum (Dm) and phosphorus desorption ratio (Dr) increased, with 2.0 LR yielding the highest values (124 mg/kg and 23.6 percent for Ay soil, and 77.3 mg/kg and 20.3 percent for Se soil, respectively). The results suggested that applying lime according to the lime requirement test, especially 2.0 LR, is the best option to promote the release of phosphorus in post-active acid sulfate soils.

Abstract

One of the challenges faced by current forestry practice is how to effectively respond to the great environmental and global changes to achieve biodiversity conservation and the demands for timber and other non-wood forest products. Worldwide forestry suggests that the approach of ecological silviculture can provide efficient tools for facing these challenges. The applied forest land management during the last seven decades in Greece relies on the principles of sustainability set by ecological silviculture through time. Greek silviculturists adopted these principles many years ago by setting the following priorities and perspectives for applied Greek forestry: the protection of all Greek forests, the systematic rehabilitation of degraded forests (e.g., conversion of coppices to high forest), the promotion of tree species mixture, the improvement of the horizontal and vertical structure of all forest ecosystems, the exclusive use of species natural regeneration, the application of selective felling prohibiting any of clear-cutting, the extensive use of low impact harvesting practices, the retention of a small number of old trees for promoting biodiversity, the protection of all rare and endangered flora and fauna species, and establishment forest protected areas. In this study, three modern indicators were used to evaluate the results of the above silvicultural ecological approach to Greek forests after a period of seven years of forestry practice based on these principles.

Abstract

Tailing land reclamation aims to improve the environment so that the tailing areas become productive for crop cultivation. The research was carried out in the tailings area of Mile 21.5 Timika from March to September 2022. The research aimed to study the dosage levels of Pistia stratiotes composts as an ameliorant to support the growth and yield of chili cultivated in the fresh tailings area. This study was laid out in a randomized block design with the Pistia stratiotes compost as a treatment, which consisted of PS1 = 1 kg/plant, PS2 = 2 kg/plant, PS3 = 3 kg/plant, and PS4 = 4 kg/plant in 6 replications. Based on the results, there was a significant effect of Pistia stratiotes compost on the growth and yields of chili. PS4 treatment produced the highest growth (plant height and leaf number) and highest yields (fruit number/plant, fruit weight/plant, fruit weight/plot, fruit weight/ha), while PS1 produced the lowest growth and yields. Chili produced 4.19 t/ha by PS4, indicating a high yield potential when tailings turned into a more stable growth media over time. There was a significant correlation between plant height and leaf number with the fruit weight. This shows that the vegetative growth component is closely related to increased chili yields. The high heritability value indicates the genetic factor influenced the growth and yields of chili more than the environmental factors. The metal contents in the chili fruit tissue are below the threshold level. The findings of this study emphasized the appropriate reclamation approaches using Pistia stratiotes compost as an ameliorant, which effectively improves the quality of tailing as growing media to maximize chili yields.

Abstract

Indonesia is in the ring of fire, which has an impact on the characteristics of volcanoes, one of which is Mount Raung. Mount Raung, part of the Iyang-Argopura mountains, has a role in influencing the development of soil types and the environment; it was recorded in 1586, 1987, 1597, and 1638. Soil types and environmental parameters have an influence on critical land conditions. Remote sensing technology has been used in various fields, one of which is land evaluation. This study examined the distribution of soil characteristics and the mapping of critical lands through remote sensing approaches. The method used to identify the morphological characteristics of soil classification and the potential for critical land was a descriptive-exploratory method. The results of the research on soil types are divided into three orders, namely Andisols, Inceptisols, and Alfisols. The three land orders are divided into nine great groups, with Lithic Eutrudepts having the highest area of 38.02%, followed by Typic Hapludalfs (21.70%), Typic Eutrudepts (9.79%), Typic Epiaquepts (7.84%), Aquic Eutrudepts (7.71%), Aquic Eutrudepts (5.64%), Fluventic Epiaquepts (5.30%), Typic Udivitrands (2.16%), and Vitric Hapludands (1.83%). Critical land based on the analysis of five factors of erosion, land use, slope, rainfall, and soil canopy density, is divided into four criteria i.e., critical area of 895.88 ha, medium critical 9,027.69 ha, and lightly critical of 14,096.89 ha. Land use, slope, and plant canopy density play a major role in the potential for critical land with a strong-very-strong level of closeness (0.350-0.610).
