Abstract

Coffee is a national strategic commodity that contributes to Indonesia’s foreign exchange, but its productivity remains low due to cultivation on low potential land. This study aimed to determine the land suitability of endemic liberica coffee using two different methods and formulate recommendations for land management in Pinogu Plateau. Thirteen land units were surveyed, and soil samples were collected and analyzed in the laboratory to identify the land characteristics. Land suitability classes (LSCs) were compared by limiting factor and parametric methods. Analysis using the limiting factor method showed that the actual LSCs for liberica coffee consisted of moderately suitable (S2) and marginally suitable (S3) classes. Efforts for improvement could increase the potential of LSC to became very suitable (S1) and S2 classes. Meanwhile, the assessment with the parametric method indicated that the LSC consisted of S1, S2, and S3 classes. These results revealed that the parametric method provides more realistic land characteristics than the limiting factor method. Land management II  or the land that had a little limiting factor turned out to be more dominant with the recommendation of adding P and organic fertilizer.

Abstract

Arbuscular mycorrhiza (AM) is known as multifunctional fungi for plant helpers under adverse conditions. However, studies that focused on the production strategy of AM biofertilizers with specific targets related to the soil limitations are limited. This study aimed to examine AM inocula from several sources using various compositions of acid mineral soil-based media and maize hosts in pot cultures to obtain effective AM inocula to handle the phosphor (P) limitations in acid mineral soils. Zeolite and Inceptisols were used as comparing media. The study utilized a completely randomized factorial design with two factors, namely C = media composition (C0: zeolite; C1: representative media of Alfisols; C2: typical media of a mixture of Alfisols, Oxisols, and Ultisols; C3: typical media with the addition of Bio-RP nutrition; C4: Inceptisols) and I = AM inoculum source (I0: without inoculum; I1: inoculum from Alfisols; I2: mixed inoculum from Alfisols, Ultisols, and Oxisols; I3: mixed inoculum from eight soil types), and six replications per treatment combination. The AM cultures on acid mineral soil-based media, which yielded the highest mycorrhizal infection, spore reproduction, and glomalin content, were C1I2 and C3I2, while the highest maize growth and P concentration were obtained with C1I1, CII2, C2I1, and C3I2. Compared to all the treatments, C1I1 and C1I2 are the superior AM cultures. Further study is necessary to confirm the effectiveness of AM cultures.

Abstract

Soil quality is the ability of the soil to perform its function, such as providing nourishment to the plants. However, intensive paddy farming, such as Hazton’s paddy farming method, is suspected to deteriorate soil quality status and degrade land sustainability. This study aimed to analyze soil quality under Hazton’s paddy farming. This study was conducted on paddy fields in Banyumas Regency using a randomized block design with treatment consisting of 1) conventional method as a control, 2) Hazton’s method + organic fertilizer, 3) Hazton’s method + organic fertilizer + decomposer, and 4) Hazton’s method + organic fertilizer + decomposer + leaf fertilizer. Soil quality was determined according to a minimum data set (MDS) that consisted of organic C, pH, total N, available phosphorus (P) and potassium (K), base saturation (BS), cation exchange capacity (CEC), bacterial density, soil respiration, and C/N ratio. The MDS was scored and calculated using the soil quality index formula and then classified from very low to very high (<0.19-1). This study highlighted that the soil quality in paddy farm using Hazton’s method in Banyumas Regency ranged from low (0.444) to very low (0.308). The application of organic fertilizer is not sufficient enough to refill the nutrient pool equal to harvested plant biomass. This leads to soil quality deterioration and affects land sustainability. Therefore, yield and biomass production should be included as soil quality indicators in future studies. Additionally, further soil degradation can be avoided by continuously assessing soil quality and the necessary conservation measures for preventing and minimizing further land degradation can be applied.

Abstract

Bio-farming is an eco-friendly advance that minimizes the required chemical additives for optimizing the quality of crops that their storage is often accompanied by seeds’ components degradation. Magnetic treatment of seed was considered as a promising tool improves germination and growth. This study aims to evaluate the effect of individual and combined application of bio-fertilizers and the N-P-K mineral fertilizers preceded by magnetic treatment of dry and/or water-soaked seeds before sowing on the yield and quality of soybean cultivated in a saline soil.The field experiment was carried out in a split-split plot design with triplicates. The main two factors (F1) were not bio-fertilized and bio-fertilized plots. The sub-factors (F2) were three application rates (A: 50%, B: 75%, and C: 100%) of recommended doses of the three N, P, K fertilizers. The sub-sub factors (F3) were seeds not magnetically treated (NM) and magnetically treated (M). All factors were studied for dry soybean seeds (without soaking) and soaked seeds in magnetically treated water. After harvesting, soil and plant samples were analyzed. The most significant increase in the soybean seed yield (kg ha-1) was by 49.98% for the bio-fertilized magnetized dry seeds at 75% and 100% mineral N-P-K fertilization compared with the NM soaked seeds at 50% N-P-K (A rate) without bio-fertilization. The 75% mineral fertilization significantly increased the protein (%) by 41.69% and decreased the proline (mg g-1dw) by 46.68%. Magnetic treatment of seeds before cultivation and combined bio/mineral N-P-K fertilization reduced the Proline that alleviats the stress conditions.

Abstract

Intensive chemical fertilizer use has led to environmental problems, ecological impacts, and dependence on chemical fertilizers. Microbial inoculants (biofertilizers) combined with mineral fertilizers can be used to establish an environmentally friendly and sustainable agricultural practice. This study aimed to observe the effectiveness of multifunctional microbes (S. pasteuri and A. costaricaensis) in their wild-type and mutant forms. The microbes can simultaneously solubilize phosphorus and potassium from minerals (rock P and feldspar) to support maize growth and yield. Microbial viability in the zeolite carrier was tested, and the treatment was applied to the field to determine the effect on maize growth and yield. The results showed that zeolite could maintain the microbe population at an average of 108 CFU g-1 during 4 months of storage. A field test revealed that all microbes treatments combined with minerals without the addition of chemical fertilizers could support maize growth and yield by producing maize ear. In particular, mutant A. costaricaensis can support dry stalk weight and maize ear length as effective as chemical fertilizers due to its ability to increase available P and exchangeable K in the soil. Overall, microbes could provide P but not K from the minerals and soil for plant uptake.

Abstract

This study was conducted to identify suitable sites for shrimp farming combined with the mangrove development (SFM) in the coastal area of central Vietnam. An integrated approach using GIS with weighted Multi-Criteria Evaluation (MCE) by Analytic Hierarchy Process (AHP) was adopted for the selection of sites. In this study, fifteen sub-criteria belonging to three main criteria (geographical conditions, water quality and infrastructure availability) were selected as evaluation parameters in the GIS model. The study indicated that the geographical factors are the most important for the SFM development with 0.44 weight. However, the availability of such areas is limited. Results of the integrated study indicated that SFM area for development is highly suitable: 1127.82 ha (15.57%), moderately suitable: 2056.87 ha (28.4%), marginally suitable: 2835.52 ha (39.16 %) and not suitable: 3204.36 ha (17.0 %) in the Hau basin, Vietnam. In this study, we have also used GIS-AHP-MCE methods for developing organic shrimp farming and mangrove rehabilitation.

Abstract

Globally, biochar research and its application for soil improvement have attracted the interest of many researchers, primarily environmental and soil scientists, in the last decade. But, a limited number of biochar research studies have been conducted in Bangladesh. Therefore, a comprehensive study on biochar research is necessary to find out the scope and opportunities of biochar application in the soils of Bangladesh. Generally, biochar can improve the physical, chemical, and biological properties of soils. It also has a significant role in greenhouse gas emissions. The contaminated soils can also be remediated through the judicious application of biochar. In Bangladesh, biochar application enhanced soil pH, organic matter, phosphorus availability, and agricultural production while decreasing soil acidification, microbial activity, and heavy metals mobility. Besides that, there were both positive and negative findings regarding nitrogen availability, greenhouse gas emissions, and heavy metal accumulation. However, this review includes the selection of feedstock, the advancement of pyrolysis technology, the characterization of biochar, and the agronomic and environmental benefits of biochar use. This paper also reviews biochar study and application activities in Bangladesh over the last decade. Further research directions have been suggested to ensure the beneficial and safe application of biochar to agricultural property.

Abstract

As an ameliorant, rice husk biochar (RHB) can improve soil quality and long-term carbon absorption and interaction with glyphosate during adsorption. This study investigated the ability of Inceptisol ameliorated with RHB to absorb glyphosate. Inceptisol ameliorated with 40-t ha-1 RHB increased the soil surface charge (ΔpH) by improving soil pH H2O, electrical conductivity, cation exchange capacity, and soil organic matter. Linear and nonlinear models showed that fitting Langmuir and Freundlich isotherms is suitable for this study. The isotherm adsorption of glyphosate sequentially occurs in the Freundlich and Langmuir models (Inceptisol + 40-t ha-1 RHB > Inceptisol), where the Freundlich model (R2 = 0.938) is dominated by glyphosate adsorption on Inceptisol + 40-t ha-1 RHB with n of 0.46 and KF of 1.747 mg kg-1, whereas the Langmuir model (R2 = 0.8608) with Qm of 30.01 mg kg-1 and KL of 0.08 L mg-1 at a concentration level of 100 ppm and pH of the glyphosate solution 5.20 units. The glyphosate adsorption was also supported by changes in functional groups, where Fourier transform infrared spectroscopy shows a decrease in transmittance in the O-H; C=C; C-O; C-H, and mineral groups, indicating an increase in the adsorption capacity in Inceptisol ameliorated with 40-t ha-1 RHB. This study indicated that the physicochemical properties of Inceptisol are important in controlling the glyphosate adsorption ability of RHB in soils.

Abstract

The same rainfall can cause different degrees of water stress depending on soil type, so the production response shown by plants can be different. This study is essential for growers, especially in predicting oil palm production based on water deficit for each soil type. The study was conducted on oil palm plantations in Central Kalimantan, Indonesia, with four soil types in 1,446.15 ha (40 blocks). The source of data collected from oil palm plantations included bunch number, average bunch weight, rainfall, and soil physical and chemical properties for the last 15 years (2007 - 2021). This experimental study used a two-stage cluster sampling method. The results showed that the best productivity, bunch number, and average bunch weight were found on Ultisols. The four soil types tested showed the same annual production distribution dynamic, but the response rate from each soil type showed differences. Entisols and Spodosols were more prone to drought stress due to water deficit than Ultisols and Histosols because of the differences in soil texture. Water deficit causes a decrease in oil palm productivity by 5 - 22% in the first year (Ultisols 12 - 22%; Entisols 12 - 22%; Spodosols 7 - 19%;  Histosols 5 - 15%) and 1 - 8% in the second year (Ultisols 3 - 7%; Entisols 2 - 4%; Spodosols 5 - 8%; Histosols 1 - 5%) compared to previous years production. A decrease in oil palm productivity occurs at 3 - 5 months (bunch failure phase), 1 year (abortion sensitive phase), and 2 - 2.5 years (sex differentiation phase) after a water deficit appears.

Abstract

Tulis is one of the watersheds in the Mrica Reservoir Catchment Area in Indonesia. The Tulis Watershed has an area of 12,750 ha, which is dominated by hilly areas with areas below alluvial-colluvial. This study aimed to map the potential distribution of the landslides in the Tulis Watershed. As the Tulis Watershed has the potential for landslides, this study was conducted by using Shuttle Radar Topography Mission (SRTM) imagery year 2016. This study considered five aspects that affect landslides, namely: geological type, soil regolith depth, fault, slope, and soil texture. Areas in the Tulis Watershed were classified into five levels of landslide potential The following landslide classes and the area they cover were predicted after applying the formula: very low (0%), low (48%, 6,126 ha), moderate (51%, 6,548 ha), high (0.5%, 63 ha), and very high (0.1%, 13 ha). From the results of the level of potential landslides, several prevention and mitigation measures are recommended according to the level. For shallow landslide levels, it is recommended that relocation centers should be set up. In contrast, for those areas with very high landslide potential, it is necessary to mitigate and install Early Warning System (EWS) tools and prepare the community for adaptation.
