Abstract

This study was conducted to investigate the effect of level soil bund stabilized with Vetiver grass and soil bund age on selected soil physicochemical properties on Somodo watershed, Jimma Zone, South-western, Ethiopia. A reconnaissance survey was conducted to identify a representative sampling site. From the selected sampling site croplands with level soil bund aged three years, six years and adjacent untreated cropland were identified. A total of 108 composite soil samples (3 treatments * 6 replications * 2 depths * 3 zones) were collected. Soil samples were analyzed following standard laboratory analysis. Ages of level soil bund (LSB) significantly affected SMC (soil moisture content) (p<0.01), BD (bulk density) (p<0.01), and SOC (soil organic carbon) (p<0.01). Zones showed significant difference in sand content (p<0.05), SMC (p<0.01), BD (p<0.05) and SOC (p<0.01). Moreover, the soil depths also significantly influenced silt content (p<.05), SMC (p<.01), BD (p<0.01), SOC (p<0.01), TN (total nitrogen) (p<0.01), Av.-P (available phosphorous) (p<0.01) and CEC (p<0.05). The interaction effect of the age of LSB with zone was significant for SOC (P<0.05). To sum up, the effect of the constructed level soil bund had a positive impact on selected soil physicochemical properties of the site. Therefore, the study suggests that it is essential to maintain the structure to sustain the effectiveness and scale up the technology to other watersheds with similar agroecology of the country. Further study is encouraged to understand more about the effect of the slope and Vetiver grass bund stabilization role independently on selected soil properties.

Abstract

Agriculture lands in coastal areas face the risk of increasing salinity due to the influence of sea water. Salinity poses complex problems for plants at all growth stages which are difficult to be addressed. Trichoderma is a microorganism known to promote plant growth and to induce plant tolerance to abiotic stresses including salinity. The research aimed to evaluate effective Trichoderma for improving groundnut growth and yield in a saline environment. The research was conducted on saline soil (EC >8 dS/m) at Gesikharjo Village, Palang Sub District, Tuban District from July to October 2019. Treatments were combinations between N and P fertilization, and four Trichoderma strains and these treatments were arranged in a randomized completely block design with six replicates, using Hypoma 1 groundnut cultivar.  Soil fertility and salinity, growth, yield and yield components were recorded as observed parameters. The results showed that NP fertilization on high salinity soils (ECs of 8.80-15.91 dS/m) with low N and high P had no significant effect on all variables compared to those of N fertilization. Applications of Trichoderma increased plant height and minimized plant death as indicated by a higher percentage of plant population at harvest compared to that of without inoculation. Among the four Trichoderma strains, Trichoderma #3 and Trichoderma #4 showed more effective than the other two strains in improving plant growth based on the shoot dry weight at the R1 phase, plant height and percentage of plant population at harvest. The positive effect of Trichoderma #3 and #4 could be due to the ability to promote plant growth as well as to induce plant resistance against salinity stress. The results suggested that Trichoderma was effective to alleviate salinity stress on groundnut crops. This research was the first trial carried out in the field and therefore needs to be further investigated, including Trichoderma formulations and application techniques.

Abstract

The research aimed to investigate the morphological changes and physical dynamics conditions of the Sa’dang River associated with river sand mining activities. The research is expected to benefit the efforts of the management of sand mining in this area and enrich knowledge about the issues of river sand mining. The study was conducted in Sa’dang River sand mining area, which includes villages of Pincara, Massewwae and Mangki of Pinrang District in South Sulawesi Province, Indonesia. A field survey was conducted in October to December 2019 to see the condition of the river along with the mining activities that were taking place. Field data analysis was combined with google earth imagery data for 2006, 2014, 2017 and 2019 using ArcGIS 10.5 software to see changes in river morphology, formation and extent of point bar and channel bar, as well as changes in the area of river water bodies and non-water river bodies. The results showed that the changes in morphology and physical dynamics conditions of the Sa’dang River showed their own pattern. If sediment deposits forming point bars or channel bars were reduced, the area of river water bodies tended to increase. Or in other words, the width of the river is inversely proportional to the increase in the area of the river water body if the area of sediment deposits that form the point bar and channel bar tends to decrease.

Abstract

Understanding the composition and diversity of arbuscular mycorrhizal fungi (AMF) is imperative for potentially enhancing their ecological role in different terrestrial ecosystems. Land use can have substantial effects on AMF species composition and diversity, but such effects have been explored less in tropical landscapes. In this study, we assessed the effects of disturbances on AMF species richness, observed the potential development of AMF types to produce mycorrhizal biofertilizer bioinoculants.  This study was conducted identifying and selecting AMFs was for the purpose of managing post-mining land in Bombana District, Southeast Sulawesi, Indonesia.  AMF spores collected from the field and trap culture were directly isolated and morphologically identified. A total of 15 AMF species were identified, including 11 species from field samples and 9 species from trap cultures. We noted that five AMF species were unique to field conditions and 5 AMF species were uniquely isolated from trap culture.  It appears that Glomeraceae family contributed the highest number of species in all land-use types.  Glomus sp. 1 was the most frequent species found in all land-use types. The Simpson’s index, Shannon index and evenness ranged from 1.60 ± 0.51 to 2.40 ± 0.40; 0.41 ± 0.17 to 0.62 ± 0.17; 0.25 ± 0.10 to 0.39 ± 0.11, respectively. In this study, we found three new records of AMF species including Entrophospora colombiana, Sclerocystis microcarpa and Glomus coronatum for Indonesia, i.e. from this study, it is clear that different land-use types affected AMF spore composition and species diversity.  All AMF species found in this study were then applied to the land to improve land quality.

Abstract

The role of low molecular weight organic acids (LMWOAs) in the Philippine nickel (Ni) hyperaccumulating plant, Brackenridgea palustris ssp. foxworthyi (Elm.) P.O. Karis is not yet fully understood. Using High Performance Liquid Chromatography (HPLC), the presence of organic acids such as oxalic, citric and malic acids were determined. Average nickel concentration in the plant tissues followed the ascending order: roots>stem>leaves with values of 7,294.73 µg/g, 7,412.30 µg/g and 9,866.46 µg/g, respectively. Among the organic acids analyzed, only oxalic acid was detected in all the plant tissues at considerable concentration. Linear correlation between oxalic acid and Ni concentrations in 0.025 M HCl plant extracts generated a positive r-value of 0.0437 indicating that as Ni content increases, oxalic acid also increases. This paper suggests that oxalic acid can be synthesized by B.palustris ssp. foxworthyi, therefore, it may acts as a ligand that chelates Ni and other metals to the aboveground tissues were it gets compartmentalized. To our knowledge, this will be the first report on the presence of organic acids in the Philippine endemic Ni hyperaccumulator plant, B. palustris ssp. foxworthyi whose potential was discovered more than thirty (30) years ago.

Abstract

The establishment of the Eucalyptus urophylla plantation has a potential contribution to the improvement of dryland ecosystem productivity in East Nusa Tenggara. However, the productivity of E. urophylla stand in this area is rarely documented even though it has been managed for more than 20 years. This study was directed to evaluate the growth performance, biomass accumulation, and carbon storage in E. urophylla plantation managed by Timor Tengah Selatan Forest Management Unit (FMU). Data were collected by a field survey using N-trees sampling method. Results demonstrated the mean tree density of E. urophylla in this area was 182 trees/ha with an average stand volume of 150.12 m3/ha. The mean annual increment in volume varied from 1.83 to 19.45 m3/year. The mean biomass accumulation and carbon storage in E. urophylla plantation approached 171.76 and 52.25 Mg/ha. Around 65% of total biomass and carbon storage were accumulated in the stem. Interestingly, the relative contribution of the stem to total biomass increased slowly with diameter class increasing while the dissimilar trend was observed in root, branch, and foliage. Based on the results, this study confirmed that the existence of E. urophylla plantation could increase the productivity of dryland ecosystem in East Nusa Tenggara.

Abstract

Bayat is located in the south of central Java, Indonesia. In the quaternary deposit area, groundwater on some dug wells taste salty and previous studies discovered salty-tasted water with electrical conductivity (EC) >5000 μS/cm and chloride concentration >1000 mg/l. Local information reported that the number of wells containing salty-tasted water increased after the 6.2 Mw earthquake on May 27th, 2006 in Yogyakarta. This research aims to determine the distribution of salty-tasted groundwater and its relation with the geological condition by conducting a hydrogeological investigation. On the hydrogeological investigation, dug wells were observed for physical-chemical characteristics such as total dissolved solid (TDS) and EC; additionally, groundwater samples were collected for chloride ion analysis. Geology of the study area is mapped based on previous studies. The result showed that the high TDS/EC groundwater correlated with salty-tasted water which found in three different areas, including in the west, middle and east part of the study area. The occurrence of salty-tasted water strongly aligns with faults zone. In conclusion, deep salty-tasted water emerges not only locally near the fault zone but also associated with trapped groundwater and buried anticline. In regard to those sources, it can be predicted that in the near future more dug wells water may turn into salty-tasted water, especially in the area closed to the fault zone.

Abstract

Soil mineralogy and its effect on chemical properties of volcanic soils located in Mount Ceremai has not been studied thoroughly. The objective of the study was to assess soil mineralogy and chemical properties of volcanic soils derived from different types and ages as an integrated strategic consideration to establish nutrient management. Field research and laboratory analysis were carried out on four soil profiles derived from different parent materials, namely young lava (KM-01), young pyroclastic fall (KM-02), old lava (KM-03), and old pyroclastic fall (KM-04). Results showed that KM-04 soil had limited nutrient reserved mineral (NRM), while KM-01, KM-02, and, unexpectedly, KM-03 soil still contained high NRM. There were no apatite and K-bearing mineral found in all soils, so regular P and K fertilization were recommended. Clay composition in the surface layer of KM-01 soil was dominated by amorphous minerals, while other soils contained amorphous mineral, gibbsite, and halloysite. Although all soils contained NRM such as labradorite, augite, and hypersthene, all soils had low exchangeable cations. P retention is a serious problem for all soils, especially KM-03 which has the highest amount of allophane. Therefore, nutrient management should be focused on accelerating NRM weathering, increasing soil CEC, and improving P fertilization efficiency.

Abstract

The availability of P in acid soils may be raised through the application of phosphate solubilizing fungi (PSF). Coal fly ash (CFA) that has a high pH and contains a relatively high P may also be used to raise the availability of P in acid sois. The purpose of this study was to explore the possible use of CFA and PSF in a biochar-compost carrier to improve the availability of P and plant growth in acid soil. Combined applications of two PSF isolates (Aspergillus oryzae = F1, and Neosartorya fischeri = F2) carried in three levels of biochar-compost  (80% biochar + 20% compost = B1, 70% biochar + 30% compost = B2, and 60% biochar + 40% compost =B3), and two doses of CFA (60 t/ha = C1, and 80 t/ha = C2) were tested in this study through two experiments. The results of experiment 1 (laboratory experiment) showed that the application of N. fischeri carried in 70% biochar + 30% compost combined with 80 t CFA/ha (F2B2C2 treatment) significantly increased the available P more than other treatments. In comparison with control,  the increase of soil available P content ranged from 13% in the F1B1C1 treatment (A. oryzae in 80% biochar + 20% compost combined with 60 t CFA/ha) to 101% in the F2B2C2 treatment (N.fischeri in 70% biochar + 30% compost combined with 80 t CFA/ha). The results of experiment 2 (glasshouse experiment) showed that the highest dry weight of maize shoot was obtained by the F2B2C2 treatment that increased 123% compared to control. The highest P uptake by maize was obtained by the F2B2C2 treatment (N. fischeri in 70% biochar + 30% compost combined with 80 t CFA/ha).

Abstract

Cadmium (Cd) is a harmful metal for paddy soil that is affected by inorganic fertilizer, pesticides, and industrialization. This study aimed to investigate the Cd contents in paddy soil, plant tissue, and grain, as well as the spatial distribution of potential Cd contamination. This study was conducted in Sragen Regency on paddy fields with different management, i.e., organic paddy fields, conventional paddy fields (Alfisols, Entisols, Inceptisols, and Vertisols), and paddy fields that often use wastewater (textiles, batik, and sugar factories) for irrigation. Forest land was used as a control. This study used descriptive explorative methods based on overlay land use, soil type, and industrial distribution map of Sragen Regency. The results showed that paddy soils with different management had higher Cd content than the forest soil. Organic paddy field had the lowest Cd content in soil (0.019 ppm) and rice grain (0.0006 ppm). Approximately 1,914.4 ha (3%) of paddy field in Sragen Regency that uses sugarcane industry wastewater as irrigation had the highest soil Cd content (0.16 ppm). In contrast, the highest Cd content in rice grain (0.046 ppm) was observed in conventional paddy field. The management of paddy field and rice cultivation significantly affected Cd contamination in soil and rice grain; therefore, environmentally friendly paddy field management needs to be encouraged.
