Abstract

The biopore infiltration hole with organic material litter can increase the soil capacity to accommodate and store soil moisture. This study was aimed to determine the effect of biopores and organic material litter on soil moisture storage and the relationship of climatic conditions on soil moisture storage. The experiment was carried out on clove plantations on Ternate Island, North Maluku from December 2018 to February 2019. This study used a factorial randomized block design. The first factor was the biopores with a depth of 50 cm and 90 cm, and the second factor was 4 types of organic material litters in the form of nutmeg leaves, clove leaves, Guinea grass leaves and a mixture of clove leaves and Guinea grass. The factors observed were total soil water storage and at depths of 0-20, 20-40, 40-60 and 60-80 cm; organic matter content; C/N ratio and soil total N. Data analysis used the GenStat program with analysis of variance test (ANOVA) and Duncan's Multiple Distance Test. Results of the study showed that evaporation and percolation are climatic factors that affect water loss. Increase in soil water storage at 20-40 cm soil depth of 107.56 mm was yielded by the treatment of 50 cm biopore and Guinea grass leaf litter but it was not significantly different from the 50 cm biopore and clove leaf litter + chicken manure treatment. The treatment of biopore and organic material litter also increased the organic matter and soil total N and decreased the soil C/N ratio, but it did not have a significant effect.

Abstract

This study aimed to determine the ability of microorganisms originating from the root ecosystem (Rhizosphere) of cocoa (Theobroma cacao L) as a potential superior to biological agents. For the experiment, soil samples were observed from the rhizosphere of cocoa plants in Pandeglang Regency. At this stage, the research was focused on finding out the extent of microbe screening results from cocoa rhizosphere soil in producing phytohormones. The results from the initial selection showed a population of Azotobacter 2.8 x 105 cfu/mL, a population of Azospirillium of 0.3 x 102 cfu/mL, and a population of Phosphate-solubilizing bacteria (PSB) 4.1 x 107 cfu/mL. In the hemolysis test conducted for 9 isolates, only 1 isolate showed a negative result. From the test of the ability to produce phytohormones showed respectively from the highest values were IAA 5.467 mg/L, gibberellin 3.768 mg/L, zeatin 1.321 mg/L, and kinetin 0.886 mg/L. The land rhizosphere of Pandeglang cocoa plant had superior potential microbes which could be used as biological fertilizers.

Abstract

Rice has become the leading food commodity in Indonesia, with total production reached +54.60 million tons in 2019. However, the production tended to decrease by around 8% from 2018 to 2019, while the rice consumption increased by +1.53 tons. This study aims to develop a rice production estimation model using the soil-vegetation index transformation (MSAVI and SAVI) and soil physical properties, which has the advantage of being faster, cheaper, and more accurate than conventional methods. The soil physical properties were taken based on soil mapping units and analyzed with soil physical parameters. The results showed strong relationships between rice productivity - soil physical characteristics and rice productivity – MSAVI and EVI with r values of 0.97, 0.83, and 0.74, respectively. The soil physical properties have a better coefficient of determination and accuracy than soil-vegetation index. The prediction model of rice production by soil physical properties is formulated inward γ = -8.96+0.01 (Top Soil Sand) + 0.01 (Top Soil Silt) + 6.28 (Bulk Density) - 14.07 (Penetration) - 0.13 (Sub Soil Permeability). There is no difference in the productivity value between model and laboratory analysis result. These results indicate that the rice yield prediction model can be used for estimation purposes.

Abstract

Climate change is one of the life-threatening challenges that face the ecosphere in recent decades. Climate change exacerbates the rate and magnitude of several ongoing land degradation processes. The impact is particularly high in unindustrialized states like Ethiopia. In recognition of the impact adaptation become the policy options to minimize the adverse effects of climate change. The main objective of this research paper is to analyze the determinants of farmers’ choice of land management approaches to climate change in drought prone areas of Amhara region: the case of Lay Gayint woreda, Northwestern Ethiopia. The study employed a multistage stratified sampling procedure (purposive and simple random). Data were obtained from 232 sample households. Primary data were collected from households via questionnaires, interview and focus group discussion. The households’ land management strategies to climate change were summarized by using percentage. Binary logistic regression model was also applied to analyze the factors that influence farmers’ choice of land management strategies. The farming households of the study area have attempted to give response to the impacts of climate change; but their capacity to adapt is challenged by a number of factors. Model results indicate that, Agro ecological setting and non-farm activities are found to be the most statistically significant determinants in the adoption of land management strategies. Solving financial problems, improving extension service, providing timely information and establishing early warning system, livelihood diversification and integrated watershed management practice would enable to increase the adaptive capacity of farmers

Abstract

Understanding the relationship between soil chemical characteristics and forest productivity is importantly required to support sustainable forest management, mainly in eucalyptus plantation. This study investigated the influence of soil chemical properties on the growth performance of Eucalyptus urophylla which established in dryland ecosystems, East Nusa Tenggara. Forest inventory was undertaken by N-trees sampling in the priority locations for E. urophylla development, located in Buat, Fatukoto1, and Fatukoto2. Four parameters were selected to describe the growth performance of E. urophylla, comprising diameter, height, volume, and mean annual increment. In each sampling point, soil sample was collected at the depths of 0-10, 11-20, and 21-30 cm. Then, the sample was composited before brought to the laboratory for quality analysis. Six parameters were selected to quantify the soil chemical characteristics, namely soil acidity (pH), soil organic carbon (SOC), total nitrogen (TN), available phosphorus (Av-P), exchangeable potassium (Exc-K), and cation exchange capacity (CEC). Results found that soil chemical properties from three locations were significantly different in pH, SOC, Av-P, and CEC. However, this study recorded the content of TN and Exc-K were statistically equal among the three sites. Difference soil chemical properties were also followed by the variation growth of E. urophylla, particularly in diameter and height. The highest volume of eucalyptus stand was observed in Fatukoto1 (181.06+95.46 m3 ha-1), followed by Buat (142.67+27.19 m3 ha-1) and FatukotoII (99.09+62.46 m3 ha-1). There were four soil parameters that meaningfully affected the growth performance of E. urophylla, i.e. pH, Av-P, Exc-K, and CEC. Among those parameters, Av-P demonstrated a consistent effect on the growth performance of E. urophylla. According to these findings, this study concluded that Av-P substantially provided higher effect on the growth performance of E. urophylla than other soil chemical parameters.

Abstract

Topography and bathymetry integration is one of the essential things in providing height data. So far, the topography and bathymetry problems are the lack of height data availability, not up to date, and low vertical accuracy. The latest DTM is one of the topography data with up to date elevation with a spatial resolution of 5 m. Bathymetry extracted from SAR images. It is an alternative depth data for ocean bathymetry and inland water bathymetry. Topography and bathymetry integration is required to obtain comprehensive height data. This study aimed to integrate the latest DTM with SAR bathymetry. The method used in this integration was DEM integration. The method combined the latest DTM data with SAR bathymetry based on the correlation of the two data's standard deviation. The integration of the latest DTM with SAR bathymetry needs to consider differences in height reference fields. Two integration studies were conducted in this research-the latest DTM integration with ocean bathymetry for Rote Island. Then the integration of the latest DTM with inland water bathymetry in Lake Singkarak. The result of the integration is necessary to check the surface by generating longitudinal and cross-section profiles. Integrating the latest DTM and SAR bathymetry can be used for various mapping surveys on lands and waters.

Abstract

On acid soils, maize growth cannot be optimal because of the high content of Al, Fe, Mg, and Zn, which has the potential to poison plants. Several nutrients such as P, Cu, and S are also available in small quantities for plants, thus inhibiting growth. This study aimed to determine the effectiveness of oil palm empty fruit bunches compost and rice husk charcoal in increasing the growth and yield of maize on red-yellow podzolic acid soils. Bonanza F1 varieties were planted and treated with (T1) 5 t ha-1 of oil palm empty fruit bunches compost; (T2) 10 t ha-1 of oil palm empty fruit bunches compost; (T3) 5 t ha-1 rice husk charcoal; (T4) 10 t ha-1 rice husk charcoal; and (T5) 5 t ha-1 of oil palm empty fruit bunches compost + 5 t ha-1 of rice husk charcoal, and control plants were not given any treatment. The results showed that all treatments had a better and significantly different effect than the control plants. The application of oil palm empty fruit bunches compost and rice husk charcoal could boost plants height (149.75% - 289.88%), stems diameter (124.10% - 204.62%), number of leaves (131.01% - 223.26%), plants fresh weight (204.14% - 342.25 %), plants dry weight (136.77% - 165.76%), weight of maize cobs (178.77% - 292.72%), weight of maize cobs without maize husks (158.27% - 233.03%), maize cobs length (112.44% - 147.14%), maize cobs diameter (117.16% - 187.79%), and the weight of 100 maize kernels (110.92% - 201.72%). Among all treatments, the T5 treatment (5 t ha-1 of oil palm empty fruit bunches compost + 5 t ha-1 rice husk charcoal) was the best because it consistently gave the highest yields on all observed variables.

Abstract

Coal fly ash, resulted from coal combustion in power plants, with relatively high amounts of aluminium, iron, calcium, and magnesium oxides may modify the sorption capacity of soils. A batch experiment was conducted to examine the capacity of reclaimed mining soils (RMS) to adsorb organic carbon (OC) in response to coal fly ash application. Extraction of dissolved OC was carried out from dried albizia shoot residue and reacted with the RMS at dissolved OC concentrations varying from 0 to 175 mg C L-1 at pH 5.5. The results showed that the sorption capacity of the RMS for OC increased significantly with coal fly ash application, which may relate to increasing the contents exchangeable Ca and Mg, dithionite- and oxalate-extractable aluminium and iron, and surface areas of soils. Desorption experiment indicated that only 5-23% of the OC initially sorbed onto soil-coal fly ash interactions was freed using a single extraction step, suggesting that most of the OC is strongly sorbed to the mineral surfaces. Results of the study indicate an important role of fly ash in increasing OC sorption capacity of soils and reducing the percentage of OC sorption from the RMS-coal fly ash association.

Abstract

Degradation of soil functions in storing and cycling nutrients may be related to topography and land-use change. The research aimed to analyze the impact of land-use changes and slope positions on soil function in nutrient stock within Kalikungkuk micro watershed of East Java, Indonesia. Four different land-uses such as vegetable crops, agroforestry, shrub and forest were selected with three slope positions (e.g. ridge, slope, and valley), and three replications of each. Soil samples were collected at 0-10, 10-30, 30-50, and 50-100 cm depth of soil. Variables measured included soil properties (e.g. bulk density, soil texture, pH, CEC, soil nutrients). Slope positions impact on differences in soil physical (i.e. soil bulk density, soil texture) and chemical (i.e. total N, exchangeable K) properties. In addition, forest conversion to other land-uses (i.e. agroforestry, shrub, vegetable crops) decreased soil nutrient concentration (i.e. total C, total N, Ca, Mg, Na), and consequently resulted in degradation of soil nutrient stocks of especially C and N. The strong positive correlation between soil nutrient stock (e.g. C and N) and vegetation cover such as canopy cover, basal area, and litter (r = 0.63 – 0.78, r table 1% = 0.39) showed the benefit of biodiversity in maintaining soil function on the nutrient stock.

Abstract

Check dams are business as usual practices used to avert gully erosion development and sedimentation in the downstream areas of the humid highlands of Ethiopia. We investigated the status of check dams and their relationship with geotechnical soil properties in the sub-humid Fogera floodplain. The density of gullies in the area was more sever having about 3.6 km km-2 which shows the severity of gully erosion. Thirty-two dams constructed and monitored over one rainy season. In the beginning of the rainy season, all the dams filled up with sediments, and at the end of the monitoring period ninety five percent of them had destroyed and the remainings had partially destroyed and had sediments accumulated on one side of the gully bank. The longitudinal gradient of streams above the dams decreased due to sedimentation. The morphological change of the gully showed an increase in width-depth ratio, gully bank erosion, and sediment aggradation in the gully bed. We found that the amount of sediments deposited behind the dams were higher than the amount of eroded material. The higher clay content and Atterberg limits increased soil erodibility once the gully channel formed. The erodibility and saturation in these soils were highly contributing to gully development and reducing the effectiveness of check dams. In conclusion, it is better to adopt an integrated novel practice to control gullying than solely using check dams.
