These conditions contribute to considerable land productivity decline, especially in West Kalimantan. In response to this challenge, the current study proposes an inventive approach for soil reclamation using red mud residue, derived from bauxite ore extraction, and cow manure as restorative elements. This research delves into a novel soil restoration technique that employs red mud waste (a residual from ore refinement) in conjunction with cow manure as ameliorative agents. A distinct amalgamation of 0.2 kg of red mud and 3 kg of cow manure (T2R3) showcased superior results. The incorporation of this blend resulted in a significant increase in soil pH by 0.93 units, an increase in macronutrient content ranging from 82.84%-503.07%, and plant growth (plant height and stem diameter) increased between 32.85%-54.31% in the treatment with 0.2 kg of red mud and 3 kg of cow manure (T2R3) compared to the lower treatment of 0.1 kg of red mud and 1 kg of cow manure (T1R1).

However, the multiple definitions and varied range of drought indices pose challenges in effectively monitoring and assessing the prevalence and severity of droughts. This study aims to give a comprehensive overview of the various drought definitions found in the literature and how they have evolved based on their applications. Specifically, the focus was to shed light on the dynamic nature of drought characterization and offer insights into the factors that shaped its conceptualization over time. Within this context, this study explored three primary categories of drought indices: climatic, remote sensing, and composite. Each category was discussed in relation to its utility in specific fields, such as meteorological, agricultural, and hydrological drought assessments, along with an analysis of their strengths and limitations. Furthermore, this study presents modified meteorological drought indices that have been adapted to better monitor agricultural droughts. Additionally, the authors used geographic information systems to create a map showing the distribution of drought-related publications globally over the past decade. The findings showed that countries with arid and semi-arid climates are more actively involved in drought research, highlighting their particular interest and concern regarding the subject matter. The implications of this study emphasize the urgent need for immediate and coordinated efforts to address the escalating issue of droughts caused by climate change. By improving monitoring and assessment methods and focusing on tailored strategies in vulnerable regions, it is possible to mitigate the far-reaching consequences of drought and to build more resilient communities and ecosystems.","PeriodicalId":509941,"journal":{"name":"SAINS TANAH - Journal of Soil Science and Agroclimatology","volume":"82 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139147306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the soil properties and rice yields under temporal variation of organic rice fields. Soil sampling was conducted in organic rice fields with three temporal variations, namely 0, 4, 7, and 10 years in a tropical monsoon region in Central Java, Indonesia. Variables observed included soil organic carbon, soil carbon stock, soil microbes population, dissolved organic carbon, soil liquid limit, soil sticky limit, soil plasticity limit, soil color changing limit, soil friability, soil porosity, soil total nitrogen, soil total phosphorus, soil available sulfur, exchangeable calcium, cation exchange capacity, total potassium, bulk density, base saturation, exchangeable sodium, exchangeable potassium, and rice yield. This study confirms that soil organic carbon increased by 51.63% within 10 years (from 1.84% to 2.79%). Organic farming also improved all the physical, chemical, and biological soil properties, by the increase of soil organic carbon. However, soil organic carbon is mostly determined by soil cation exchange capacity, soil total phosphorus, and soil porosity. The mechanism of rice yield increase in organic rice farming is not affected by soil organic carbon directly but through the synergic increase in soil total nitrogen. The 1% increase of soil organic carbon increases 0.065% of soil total nitrogen hence rice yield increases by 1.66 tons ha-1. This study supports sustainable agriculture by providing evidence of improved soil properties under organic farming.","PeriodicalId":509941,"journal":{"name":"SAINS TANAH - Journal of Soil Science and Agroclimatology","volume":"173 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139170324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of UAVs can addressed these challenges. The purpose of this study was to determine the best vegetation indices (VIs) for estimating chlorophyll content, plant height (PH), canopy area (CA), and fruit total numberas (FTN). CCM 200 was used as a tool to measure the chlorophyll content index (CCI), the number of fruits was measured by hand-counter, and other variables were recorded in meters. The UAV used was a Phantom 4 with a multispectral camera capable of capturing five different bands. The VIs was obtained via analysis of digital numbers generated by the multispectral camera. Then, the VIs was correlated with the CCI, PH, CA and FTN. VIs tested included the following: the normalized difference vegetation index (NDVI), the normalized difference vegetation index-green (NDVIg), the normalized different index (NDI), green minus red (GMR), simple ratio (SR), the Visible Atmospherically Resistant Index (VARI), normalized difference red edge (NDRE), simple ratio red-edge (SRRE), the simple ratio vegetation index (SRVI), and the Canopy Chlorophyll Content Index (CCCI). The best model for predicting CCI was obtained using the NDVIg (R2=0.8480; RMSE=6.1665 and RRMSE=0.0908). Meanwhile, SR turned out to be the best model for predicting PH (R2=0.8266; RMSE=15.6432 and RRMSE=0.0883), CA (R2=0.6886; RMSE= 0.8826 and RRMSE=0.1907), and FTN (R2=0.6850; RMSE=24.5574 and RRMSE=0.3503).

Therefore, composting has been proposed to reduce methane emissions in the agricultural field. This study aimed to determine the CH4 emission and rice yield affected by compost from three different types of compost: herbal compost, eucalyptus compost, and manure compost. This randomized block design study was conducted from November 2019 to May 2020. There were 8 fertilizer treatments applied to the rice fields, namely: herbal compost 10 tons/ha. (O1), eucalyptus compost 10 tons/ha (O2), manure compost 10 tons/ha (O3), no compost no chemical fertilizer (as a control) (O4), herbal compost 5 tons/ha + chemical fertilizer/CF (C1), eucalyptus compost 5 tons/ha + CF (C2), manure compost 5 tons/ha + CF (C3), and only chemical fertilizer (C4), then all treatments replicated three times. For the chemical fertilizer (CF) the dose is 166 kg/ha urea + 166 kg/ha ZA + 330 kg/ha TSP. The result indicated that the compost manure 10 tons/ha (O3) and the combination compost manure 5 tons/ha + CF (C3) produced the highest rice yields (6.89 -6.94 tons/ha) but impacted the highest methane emissions (505.3 – 544.6 Kg.CH4 /ha/season). The important finding showed that among all the treatments, a combination of compost eucalyptus 5 tons/ha + CF (C2) and compost eucalyptus 10 tons/ha (O2) mitigated methane emission to the lowest level (296.6 -305.2 Kg.CH4/ha/season) and gave high rice yields (6.77-6.78 tons/ha) that were not significantly different from those of compost manure (O3 and C3).

This investigation looked at how well soybean seeds germinated in media containing heavy metal Fe and how the pH of the media affected the viability of soybean seeds. This research was conducted at the Seed and Plant Breeding Laboratory at the University of Lampung, Indonesia. The experimental design was a randomized block design. The first factor was seven soybean local varieties – Grobogan, Anjasmoro, Derap 1, Detap 1, Dena 1, Deja 1, and Dega 1 – and the second factor was heavy metal Fe solution pH of 6–7 and 4.5 and without heavy metal Fe (control). Seed viability in heavy metal Fe medium was assessed using radicle emergence, germination capacity or percentage, germination speed, number of normal seedlings, normal seedling hypocotyl length, main root length of regular seedlings, and normal shoot dry weight. This research found that heavy metal Fe affected soybeans’ seeds’ viability in pH 6–7 and 4.5. The observed data showed that all seeds’ viability variables in media with heavy metal Fe, both in pH 6–7 and in pH 4.5, differ from the control media. The seed viability in media heavy metal Fe pH 6–7 was not significantly different from the control media, but in pH 4.5, the difference is significant. Soybean varieties’ characteristics also influence how heavy metal Fe in different pH affects seed viability. Overall, Anjasmoro, Deja, Grobogan, and Dega were the types that consistently demonstrated resistance or adaptation to heavy metal Fe existence, while Dena, Derap, and Detap are susceptible to heavy metal Fe existence. Seed viability in Iron medium is not always related to seed physical performance; therefore, before planting soybean in acid soil, it is recommended to conduct a seed viability test.","PeriodicalId":509941,"journal":{"name":"SAINS TANAH - Journal of Soil Science and Agroclimatology","volume":"198 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139229868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted in three stages. The first stage determined the quality of five compost mixtures: C1, C2, C3, C4, and C5. The second phase of testing for cumulative N minerals was performed after 1, 2, 4, and 8 weeks of incubation. The third stage examined the impact of the compost mixture on the growth and yield of upland rice in comparison with two treatments, namely the control and NPK fertilizer. The results showed a similarity in the forms of mineralization, where the cumulative N mineral increased with the addition of peanut residue to the compost mixture. The use of a mixture of peanut residue and rice straw compost increased net mineralization by 37.27% (C5) to 59.48% (C1), N uptake by 49.19% (C5) to 62.95% (C3), and NUE by 15.04% (C4) to 51.48% (C3).

Andisols, commonly found in Indonesia, serve as agricultural areas with high, excessive, and continuous organic matter input. However, the propensity of the soil for P leaching poses a potential risk of water pollution and eutrophication in the watershed area. This study aimed to evaluate the impact of the application rate of organic matter, specifically chicken manure, often employed in agricultural activities related to Andisols. The experiment involved observing P sorption, P desorption, P sorption kinetics, and P uptake by wheat (Triticum aestivum) in soil incubated with chicken manure added at various rates of 0, 10, 20, 30, and 40 t ha-1. The incubation stages were conducted for 14 days at room temperature (27°C) and soil moisture was maintained within field capacity. The data collected were analyzed using Langmuir isotherm for P sorption and desorption, and first-order kinetics for P sorption kinetics. The results showed that the chicken manure addition at 10-40 t ha-1 significantly reduced P bonding energy in Andisols, but failed to decrease the sorption maxima value due to accumulated P from previous applications performed. The application of 20 t ha-1 (CM20) of chicken manure was found to be the optimal rate, displaying high P uptake and reduced bonding energy, while rates above 20 t ha-1 showed no significant difference in P uptake and bonding energy levels. Therefore, CM20 was recommended to increase P availability and prevent P movement into water bodies, promoting sustainable agricultural practices.","PeriodicalId":509941,"journal":{"name":"SAINS TANAH - Journal of Soil Science and Agroclimatology","volume":"32 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139251339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a symbiosis between plant and arbuscular mycorrhizal fungi can reduce the severity of the effect of salt stress on cultivated plants. The aim of this study was to determine the impact of salt stress on the antioxidant substances and biochemical parameters of chia (Salvia hispanica L.) plants that had been inoculated with the fungus Glomus manihotis. A factorial completely randomized design with seven replicates was used with status of inoculation by the fungus G. manihotis (inoculated vs. not inoculated) as one of factors and the concentration of sodium chloride (NaCl) (0, 50, 100, and 200 mM) as the other status factor. Several parameters in the chia plants were measured including: root infection, phosphorus content, chlorophyll and carotenoid contents, antioxidant enzyme activities (superoxide dismutase and catalase), and malondialdehyde content. The results showed that chia plants inoculated with G. manihotis (mycorrhizal plants), even under salt stress conditions, had higher phosphorus content than non-mycorrhizal plants. High salt levels reduced the percentage of root infection by the mycorrhizal fungus of G. manihotis. Under salt stress conditions, chlorophyll and carotenoid contents of chia leaves were higher in mycorrhizal plants than in non-mycorrhizal plants. The activities of superoxide dismutase and catalase of mycorrhizal chia plants were higher than those of non-mycorrhizal plants, even though they were grown under conditions of high salt levels. The malondialdehyde content of chia plants increased with salt concentration, but decreased in chia plants inoculated with G. manihotis. The findings of this study indicate that G. manihotis inoculation is effective in reducing the effect of salt stress on chia plants.","PeriodicalId":509941,"journal":{"name":"SAINS TANAH - Journal of Soil Science and Agroclimatology","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139263066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
