Abstract

The use of phosphorus and potassium-solubilizing microbes as biofertilizers is an alternative method to increase the availability of phosphorus and potassium in soils. This study aimed to explore the effectiveness of phosphorus (P) and potassium (K)-solubilizing multifunctional microbes (Aspergillus costaricaensis and Staphylococcus pasteuri mutants) on maize growth. The stages of this study consisted of viability test of P and K solubilizing A. costaricaensis and S. pasteuri mutants in peat and effectiveness test of P and K solubilizing A. costaricaensis and S. pasteuri mutants on maize growth. The results showed that peat carriers could keep the fungi population stable until 18 weeks of storage times. While the bacteria at 6 and 8 weeks storage times showed a slight decrease and stable in the 10 to 12 weeks storage time. The addition of P and K-solubilizing multifunctional microbes could reduce the use of fertilizer up to 50% in the treatment with a combination of easily soluble P or K sources with not-easily soluble P or K sources, as well as a combination of treatments of not-easily soluble P and K sources. This tended to occur in the treatment with the addition of A. costaricaensis mutant.

Abstract

Determination of soil quality in Giriwoyo Sub-district, Wonogiri Regency, will generate a Soil Quality Index which can be used as a reference for soil cultivation for optimal productivity. This research was a descriptive exploratory with a survey approach. The survey area consisted of 12 land mapping units (LMU) with 3 replications for each LMU. Determination of LMU based on soil type, land use, slope and rainfall. The parameters used were BD (bulk density), porosity, organic C, pH, CEC (cation exchange capacity), BS (base saturation), available P, available K, total N, and MBC (microbial biomass carbon) that represented the physical, chemical and biological properties of the soil. Principal Component Analysis (PCA) analysis was performed to obtain the Minimum Data Set (MDS). The Soil Quality Index (SQI) at each LMU was calculated by multiplying the PCA result score (Wi) with the score for each selected indicator (Si). The result showed that the Soil Quality Index at each LMU was low. The highest Soil Quality Index was found in fields land use with an SQI of 0.34. The soil indicator that limited the soil quality was available P.

Abstract

Worldwide human activities are the driving force for land degradation; these difficulties will worsen without immediate remedial action. This pressing global issue affects mankind, especially rural communities. The indicators for land degradation is mostly reduction in benefits derived from land. Bamboo is a grass type with a very large woody stem. Bamboo forests are important both for land restoration and socio-economic value. This review paper is aimed to assess land restoration and socio-economic contributions of bamboo in Ethiopia. Ethiopia is the leading bamboo resource country in Africa. Assosa, Injibara, Gimbi, Ambo, Gurage, Bale, Masha, Chencha and Hagere-Selam are the known bamboo producing areas of Ethiopia. Basically, bamboo is considered a good plant for restoring degraded land and soil health. Bamboo has great benefits for income diversification and other socio-economic values. Additionally, bamboo plants have so many cultural and medicinal uses in many parts of Ethiopia. Though a variety of studies revealed that bamboo has a unique ability in restoring lands condition, but less attention was given for its biological soil conservation, so concerned body should create awareness regarding the importance of bamboo for soil and water conservation. Ethiopia has numerous hectares of natural bamboo, known in the African continent. But, the real benefits generated from this subsector is insignificant so, the concerned body should improve benefits obtained from bamboo. Bamboo production and processing provides job opportunities and creates economic and social stability, however, there is little attention given, and so concerned body should give special attention for this sub-sector.

Abstract

Pre-growing weed control by glyphosate herbicides is effective for increasing yield, but glyphosate residues in the soil might reduce soil quality and can accumulate in agricultural products. Naturally, microbes are able to breakdown glyphosate into nontoxic substances orthophosphate and glycine. Glyphosate degradation in soil by single soil microbes are reported elsewhere, but the information about glyphosate removal by soil bacterial consortia was limited. The objective of this research was to determine the effect of carbon (C), nitrogen (N), and phosphorus (P) composition in liquid media to increase glyphosate degradation and its degradation product by soil bacterial consortia and 2) verify the effect of bacterial consortia on maize seedlings growth, their N and P uptake, as well as total and soluble P in soil. Glyphosate degradation test was set up by incubating bacterial consortia in a different composition of C-N-P liquid basal media. Greenhouse experiment has been performed in a randomized block design to treat maize grown in Inceptisols with bacterial and glyphosate application. The results showed that C-N-P composition of liquid media affected the concentration of glyphosate, as well as orthophosphate and glycine as by-products. In-planta experiment verified that inoculation of glyphosate-degrading bacterial to maize seedling grown in glyphosate-contaminated soil enabled to enhance shoot dry weight of maize seedling and N and P uptake at 4 weeks after inoculation.

Abstract

Cover crop is an important factor which affects soil loss. The lost of soil potential is affected by plant morphology. The aim of this study was to elaborate on the effectiveness of the type of cover crops to soil loss in the same morphology and characteristic of soil. The study was carried out by applying erosion plots. Soil loss measurements were conducted four times in each demonstration plot. Soil loss for each plot was analyzed in the laboratory. The result showed that the most erodible soil with the highest amount of soil loss was in the pre onion plot and the most effectiveness for soil loss control was carrot plot. The amounts of soil loss for carrot, cabbage, and pre-onion were 0.040991 kg/8 x 10-4ha, 0.069901 kg/8 x 10-4ha, and 0.077800 kg/8 x 10-4ha, respectively. The highest runoff of 60.554 L/8 x 10-4ha,  was observed at the pre onion plot. Based on the result, the most effective cover crop for soil control was the carrot. The important parts of cover crops which influenced soil loss were the shape of shade leaves and type of roots.

Abstract

Simulation of land and water management for the irrigated farmlands has become an interest to answer how agricultural productivity is related to the water use in a river basin. This research was undertaken in the Brantas River Basin in Indonesia, involving a modelling process with the virtual water concept as a tool to analyze water productivity. The research simulated the agricultural water demand and provided the results of the virtual water content of paddy and maize, based on the available farming land, water availability, cropping pattern and climatological conditions of the respective hydrological years of 1997 and 2011 as a benchmark. After which projections were made based on the low rainfall scenario for the years 2021 to 2025. The research concluded that the presence of excess irrigation in the tropical climates hinders the increase in agricultural productivity, and therefore, the irrigation in the Brantas River Basin needs to be improved by, among others, selecting plants with higher water productivity, developing water-sensitive cropping patterns, and water conveyance savings.

Abstract

Land degradation manifested in landscape change is triggered by soil erosion and it is a thoughtful environmental threat. Nationally, soil loss costs 23% of the national annual GDP. Thus, identifying and prioritizing land degraded areas for conservation in regional planning and resource conservation is the priority of land degradation management. Therefore, identification of erosion hazard area and land use and/or land cover (LULC) dynamics are the overall objectives of the study. GIS and Remote Sensing technology was used to identify erosion hazard areas. K-factor, R-factor, LS factor, P-factor, and C-factor, parameters were derived from mean rainfall, Digital Elevation Model, soil map, LULC map, and ground truth points of all the parameters used to identify erosion hazard areas. At the last, the aggregate effect of those parameters had been analyzed and erosion hazard areas were identified. The Revised Universal Soil Loss Equation (RUSEL) was employed to estimate the annual soil loss of the area. The analysis result unveils that within 20 years interval cultivated land, urban land, and bare land show that a dramatically increasing and forest land shows that decreasing rate. The district has undergone significant changes. Portions of the study area that has the highest slope gradient, the highest amount of rainfall, and consist of Nitosols on agricultural land are the most erosion hazard areas. Statistically, nearly 49%, 19.78%, 9.58%, and 5.45% of the study area coverage lower than moderate, high, very high, and severe soil erosion class correspondingly. Annually losses on average of 41.07 t ha-1yr-1 soil loss because the area is intensively cultivated and experiences relatively high rainfall, and steep slope. The share of the study area, southern part, and northeastern portion of Debre Tabor district are exposed to high erosion hazard class compared to other parts.

Abstract

Land subsidence had been a significant problem in DKI Jakarta and Semarang, with at least 20 kilometres of roads affected. Repairing them will require at least US $ 1 million per kilometre. Land subsidence monitoring has been carried out using terrestrial methods (GPS and levelling), which are believed to have a high degree of accuracy. The high accuracy of the terrestrial method results in a lack of precision over a large area. On the other hand, remote sensing technology as a non-terrestrial method has developed to monitor land subsidence which can produce high precision over a large area. This study aimed to test the Sentinel-1 satellite data using the Differential Interferometric Synthetic Aperture Radar (DInSAR) method in monitoring land subsidence in DKI Jakarta. DInSAR is a method in Remote Sensing that utilizes radar sensors to analyze the phase differences of a SAR data pair that have different times of capture and have been catalogued to obtain displacement along the area of collection. The results showed that the North Jakarta area experienced the highest land subsidence in the entire Jakarta area. The annual average rate from 2017-2019 is 3.4 cm. The value of 3.4 cm is the average value of all samples in the North Jakarta area. The second area where high land subsidence is West Jakarta, where the maximum amount value of subsidence is 2.8 cm. The accuracy-test results with the MONAS test point showed that the difference between field data and DInSAR results was ± 6.5 cm. The results of this research indicate that the DInSAR method is quite capable of describing land subsidence in the DKI Jakarta area with a relatively good level of precision.

Abstract

A large part of post-tin mining land covered by sand tailing which has low water storage capacity, making it vulnerable to drought stress. The innovation of irrigation technology has been developed to overcome this problem such as capillary irrigation system combined with groasis system using a large reservoir with hydroponic wick system called the growick system. This study aimed to determine the best number and type of wick in growick irrigation system to water consumption and also growth and yield of pakcoy cultivated in sand tailing media. The research was conducted from February to June 2020 at Experimental field of Universitas Bangka Belitung, Indonesia. Treatments consisted of the types of wick (flannel and stove wick) and numbers of wick per polybag (1, 2, 3, and 4 wicks). The study used a completely randomized factorial design with 3 replications. Data obtained were analyzed using Analysis of Variance continued with Duncan's Multiple Range Test (DMRT) at 95% significant level. The result showed that usage of flannel wick gave the highest results of growth and yield of pakcoy but it absorbed more water than stove wick. Flannel wick also had lower water usage efficiency than stove wick. The use of single wick gave the highest result of growth and yield of pakcoy than using more wicks. Results of the study showed that single wick treatment gave the highest growth and yield of pakcoy. Flannel wick gave the highest growth and yield of pakcoy, but it was not significantly different from stove wick. Single flannel wick treatment showed no significant difference with single stove wick treatment in growth and yield of pakcoy except for water usage volume parameter. Flannel wick absorbed more water than stove wick, so it has lower water usage efficiency than stove wick. Application growick system using 1 stove wick was the best treatment for cultivating pakcoy in sand tailing media from post-tin mining land.

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.
