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

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.

Abstract

The development of tourism and leisure infrastructure results in a continuous increase of anthropogenic impact on soils of wet and dry subtropics of the Greatest Caucasus. It is very important for the region to preserve the sustainable functions of soils and ecosystems, maintain a comfortable life and recreation environment create environmentally friendly agricultural products. It is conducted studies to determine the limits of resistance of soils in wet and dry sub-tropics to priority pollutants, especially petroleum hydrocarbons and heavy metals (Pb, Cr, Cu, Ni). It was found that the soils of wet and dry subtropics for resistance by Pb, Cr, Cu, and Ni are located as follows: south-ern chernozem > typical sod-carbonate soil ≥ brown typical soil ≥ brown carbonate soil = brown leached soil ≥ leached sod-carbonate soil = yellow soil >acid brown forest soil ≥ acid brown forest podzolized soil. In terms of the degree of resistance to oil pollution, studied soils create certain series: brown carbonate ≥ brown typical = sod-carbonate leached ≥ sod-carbonate typical > southern chernozem ≥ yellow soil ≥ brown leached soil > acid brown forest soil = acid brown forest podzolized soil. Heavy metals by ecotoxicity to the soils of wet and dry subtropics from the following series: Cr> Cu ≥ Ni = Pb. Based on the degradation of ecological functions of soils, we offer regional standards of the maximum permissible content of Pb, Cr, Cu, and Ni for the main soils of wet and dry subtropics.

Abstract

Rainfed farming is vulnerable to climate variability, which changes rainfall patterns.  Rainfall variability disrupts rainfed rice cultivation because a  change in rainfall will affect the rice crop calendar. An analysis of long-term trends over a specific area is required to understand rainfall variability. The aim of this study was to assess climate variability in terms of rainfall magnitude and frequency by analyzing spatial and temporal rainfall trends in Bengawan Solo Sub-Watershed as well as the rainfed rice production. Daily rainfall data from 10 rain gauge stations over the sub-watershed area from the years 1975 to 2020 were used. The data was managed and collected by the Bengawan Solo Watershed authority. Pearson, Mann-Kendall, and Sen’s Slope tests were applied to assess the recorded data correlation, rainfall trends, and magnitude of trends into annual, monthly, and 10-day. The findings of the study indicated the spatial and temporal inhomogeneous rainfall pattern for all locations for 10-day, monthly and annual patterns. The mountainous regions at Tawang Mangu and Ngrambe stations tend to experience an upward trend (positive magnitude), while the coastal regions at Nglirip and Bojonegoro stations have a downward trend(negative magnitude). Those trends also confirmed that coastal regions would be drier than mountainous regions in the future. Understanding this rainfall trend can assist with rainfed farming strategic planning.

Abstract

Low nutrient retention and soil organic matter depletion are the major challenges of the cropping system in the sandy loam soils of Northern Lombok, Indonesia. A field experiment was conducted to evaluate the influence of biochar-based organic amendments on the soil quality of sandy loam soils under cassava (Manihot Esculenta, Crants)–peanut (Arachis Hypogeae L.) cropping sequence. The treatments were as follows: biochar (10 ton ha-1) and rice straw  (3 ton ha-1)  (B1);  biochar  (10 ton ha-1), cattle manure (10 ton ha-1), and rice straw (3 ton ha-1) (B2);  biochar (10 ton ha-1)  and cattle manure (10 ton ha-1) (B3);  biochar (10 ton ha-1) and cattle manure (10 ton ha-1) plus rice straw mulch (3 ton ha-1) applied on surface soils (B4),  and without organic amendments (B0) as control. Results showed that the biochar-based organic amendments significantly improved several soil quality indicators such as SOC, total N, available P, Ca, cation-exchange capacity (CEC), and aggregate stability but had no significant effect on pH, K, and Mg. Improvement in soil quality was strongly indicated by an increase in the growth and yield of cassava and peanuts. Treatments B1, B2, B3, and B4 generally had a comparable effect on soil parameters and tended to improve the growth and yield of cassava and peanuts. Cassava was responsive to treatments B2 (biochar, cattle manure, and rice straw) and B3 (biochar and cattle manure) with its actual yield of 27 tons ha−1, which is a 40% increase compared with that in the control. As a secondary crop growing after cassava, peanuts also exhibited higher yields in all amended plots compared with that in the control. The highest yield was obtained in B2 (1.38 ton ha−1), followed by B4 (1.36 ton ha−1), B1 (1.33 ton ha−1), and B3 (1.25 ton ha−1). In conclusion, the incorporation of biochar, cattle manure, and crop residues (rice straw) into soils is a promising option to maintain soil quality and sustainably produce cassava and peanuts in the sandy loam soils of the semi-arid tropics of Lombok, Indonesia.

Abstract

The different forms of heavy metals may be significantly extracted from soils by plant roots. In a glasshouse experiment, the shifting of soil heavy metal forms under thorny amaranth was examined. To accomplish the research goal, thorny amaranth was planted for four weeks at field water content in soils with varying Cu and Zn contents. Copper and Zn levels in the soil were measured both before and after planting. High soil Cu and Zn levels reduced this plant's height and dry biomasses. Thorny amaranth considerably reduced the exchangeable and available Cu and Zn in the soil. The soil exchangeable and available Cu and Zn had a good correlation with the plant uptakes of these elements. Copper and Zn reductions by planting significantly lower than the available Cu and Zn. A significant portion of the soil exchangeable Cu and Zn shifted to stronger bonding during the incubation time. It was demonstrated that plants absorbed more Cu and Zn from forms different than the soil-exchangeable forms.
