Previous studies have explored some of the effects of water nutrient status under such conditions; however, the relationship between water nutrient status in these cultivation conditions and the growth and quality of wasabi is still completely unknown. We evaluated the effects of nutrient strength, inorganic nitrogen sources, and pH of the medium on the growth of wasabi plants. Then, we analyzed the photosynthetic capacity and the ionomes of two major Japanese wasabi cultivars (‘Onimidori,’ an early-growing green-stem type; and ‘Mazuma No.1,’ a late-growing red-stem type) grown under a range of pH conditions. These experiments were conducted using a hydroponic system. Wasabi plants showed the best shoot and root growth in 1/10- and 1/2-strength Hoagland’s solution with a 50:50 ratio of NH4-N:NO3-N. On the basis of the accumulation patterns of NO3−, amino acids, and chlorophylls, the 1/10-strength nutrient solution provided optimal conditions for wasabi growth. For both wasabi cultivars, the best shoot and root growth was in medium at pH 6.0. The photosynthetic capacity of ‘Onimidori’ was greater than that of ‘Mazuma No.1,’ suggesting that this may contribute to the faster growth of ‘Onimidori.’ Ionome analyses revealed tissue-specific mineral accumulation patterns and their differences among different pH conditions and between the two cultivars. Ionome-based multiple-regression analysis revealed a relationship between element concentration profiles in the wasabi plants, especially those in root, and the shoot growth. Wasabi plants are ammonium-sensitive and nitrate-preferring plants, in addition to relatively low nutrient requirements for optimal growth. The results of this study describe the basic nutritional characteristics of wasabi plants. These findings represent an important step toward optimizing fertilization to control wasabi quality and growth in the traditional flooded cultivation system.KEY WORDS: Ionomenitrogenphphotosynthesiswasabi AcknowledgmentsWe thank Jennifer Smith, PhD, from Edanz (https://jp.edanz.com/ac) for editing a draft of this manuscript.Disclosure statementNo potential conflict of interest was reported by the author(s).Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/00380768.2023.2276716Additional informationFundingThis work was supported by Kurita Water and Environment Foundation, number 19B001 (T.I.) and Urakami Foundation for Food and Food Culture Promotion (T.I.).","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135186729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adsorption using biochars is an easy and cost-effective wastewater treatment method. However, aquatic plants such as water hyacinth for biochar feedstock are considered unsuitable for adsorbent use due to limited NH4+-N adsorption capacity. In this study, biochar made from water hyacinth was modified with potassium hydroxide (KOH) and hydrogen peroxide (H2O2) to obtain highly efficient adsorbent. This study aimed to enhance NH4+-N adsorption capacity by KOH- and H2O2-treatments and identify NH4+-N adsorption mechanism of the modified biochars derived from water hyacinth. The NH4+-N adsorption of all biochars was dependent on the initial solution pH increasing from pH 2 to 4, then relatively constant from pH 4 to 8. Pseudo-second-order model and Langmuir model were found to be the best fit for NH4+-N adsorption data. The maximum NH4+-N adsorption capacity of biochars increased about 8 times (17.1 mg g−1) and 10 times (21.5 mg g−1) after KOH- and H2O2-modification, respectively, compared to pristine biochar (2.14 mg g−1). The main NH4+-N adsorption mechanisms were suggested as cation exchange for both biochars particularly KOH-modified biochar, and hydrogen bonding by oxygen-containing surface functional groups for H2O2-modified biochar. This study suggested that aquatic plant-based biochar, which has been considered difficult to use, had potential as a promising alternative adsorbent for removing NH4+-N from wastewater through modification.KEY WORDS: Adsorption isothermadsorption kineticscarboxylic groupcation exchange capacityFTIR Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work was supported by the Science and Technology Research Partnership for Sustainable Development [JPMJSA2005].","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136158676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, understanding the spatiotemporal characteristics of soil loss at the watershed scale is critical for sustainable management of land and water resources. The primary objective of this study was to estimate the spatiotemporal variation in water runoff and soil loss in the Tokoro River watershed (TRW), Hokkaido, Japan. Assuming that agricultural land, which becomes bare depending on the season, is the main source of erosion and that large soil losses occur especially during the snowmelt/freeze-thaw period, we quantified and analyzed the mechanism of soil loss using the Soil and Water Assessment Tool 2012 (SWAT2012). Simulation results based on a publicly available dataset showed that croplands were the primary source of stream sediment load, contributing to 86% of the total soil loss. Furthermore, the soil loss rate was high (241.1–270.9 Mg km−2 yr−1) in sub-basins with a higher percentage of cropland, especially sloped croplands. These sub-basins had a higher risk of productivity loss due to intense erosion and river contamination by muddy runoff. Soil loss mainly occurred in early spring (March and April) and late summer (August – October), accounting for 36% and 45% of the annual soil loss, respectively. Vegetation removal by harvest exacerbated soil loss in October. In March, soil drainage was suppressed by frozen soil, resulting in high surface runoff and soil loss. Therefore, surface runoff when the soil was frozen was considered an important driver of soil loss. The estimation error of the stream sediment loads out of the 95% prediction uncertainty accounted for 26% of the total absolute error. This error could be attributed a lack of certainty in the observation data of high stream sediment loads and the model’s underestimation of water runoff during intense snowmelt and rainfall events.KEYWORDS: Water erosionSWAT modelfrozen groundsnowmeltagriculture AcknowledgmentsThis research was conducted with a financial support from JST SPRING (Grant Number: JPMJSP2119).Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by JST SPRING [Grant Number: JPMJSP2119].","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial community structures involved in the redox cycle of Fe have not been revealed in the Fe-toxic paddy fields. The present study investigated the bacterial community structure and the abundance of Gallionellaceae, Geobacteraceae, and Anaeromyxobacteraceae, as the representative indicator bacteria of Fe oxidizers and reducers, in the bulk and rhizosphere soils and rice roots of a Fe-toxic paddy field in Burkina Faso (BF)in 2017–2019. Thosein a paddy field in Anjo, Japan (AN) were also analyzed for comparison. The amplicon sequencing analysis revealed that the BF rhizosphere soil was characterized by typical anaerobic bacterial groups like Firmicutes and Deltaproteobacteria, including several potential Fe reducers. The relative abundance of Gallionellaceae, lithotrophic Fe oxidizers, in the BF rice roots was significantly lower than that in the AN rice roots. Quantitative PCR analysis showed that the ratios of Gallionellaceae to Geobacteraceae and to Anaeromyxobacteraceae were higher in the rice roots than in the soils irrespective of the fields. However, the ratios of Gallionellaceae to Geobacteraceae were lower in the BF soils and roots than in the AN soils and roots. The ratios of Gallionellaceae to Anaeromyxobacteraceae in the BF soils were also lower than those in the AN soils. These findings indicated the relative predominance of Geobacter- and Anaeromyxobacter-related Fe reducers over Gallionellaceae-related Fe oxidizers in the rice rhizosphere of the BF field, corresponding well to the circumstances of Fe-toxic soil: higher Fe(II) amounts in the soil. Since Fe(II)-oxidizing activity at rice roots is an important factor as a primary defense system against Fe(II) in the soil solution, the ratios of Gallionellaceae to Geobacteraceae and to Anaeromyxobacteraceae may serve as an indicator of potential Fe(II)-oxidizing activity of rice rhizosphere. Further studies focusing on the activity of Fe oxidizers and Fe reducers at rice roots under effective cultivation practices and in various types of Fe-toxic paddy fields will help to promote a better understanding of the Fe-toxic soil circumstances and to establish sustainable rice cultivation in the Fe-toxic soils.KEYWORDS: Iron-oxidizing bacteriairon-reducing bacteriairon toxicitypaddy fieldrhizosphere AcknowledgmentsWe thank Kojima H. of Nagoya University for the measurement of Fed, Feo, and CEC, and Bagayogo A., Zougrana S., and Kiemde S. of the Institute of Environment and Agricultural Research for their help of the sampling and experiments in Burkina Faso.Disclosure statementNo potential conflict of interest was reported by the authors.Supplemental dataSupplemental data for this article can be accessed online at https://doi.org/10.1080/00380768.2023.2259426.Additional informationFundingThe present study was supported by the Grant-in-Aid from the JSPS KAKENHI [17H04619, 18K05372, a","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136062273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been pointed out that a huge discrepancy lies in the different evaluation methods of P adsorption, such as batch experiments and column experiments, which makes it difficult to demonstrate P mobility under flow conditions. The objective of this study was to evaluate the applicability of the convective-dispersion equation using the parameters of the Langmuir-type isotherm obtained from batch experiments with different reaction times: the adsorption capacity of soil (qmax) = 0.112 (g kg−1) for a Gray lowland soil with 24 h reaction time, qmax = 0.484 (g kg−1) for an Andosol (volcanic ash soil) with 24 h reaction time, and qmax = 1.17 (g kg−1) for an Andosol with 32 d reaction time, for describing P mobility in typical Japanese agricultural soils under fast flow conditions. The breakthrough curves of P infiltrating the soil columns demonstrate nonequilibrium P adsorption by the soil. The chemical nonequilibrium model, with a kinetic adsorption rate of α = 0.40 (Gray lowland soil) and 0.098 (Andosol), succeeded in describing the observations in the column experiments. Compared with Gray lowland soil, which is relatively rich in iron oxide, P mobility was largely affected by kinetic sorption in Andosol, which is relatively rich in allophane. It is suggested that the P adsorption capacity of soils should be evaluated reflecting the soil composition in order to simulate the P mobility under flow conditions. In particular, the slow adsorption (long-lasting adsorption) of P by the soil should be considered in the estimation of the P transport.KEYWORDS: Adsorption isothermAndosolGray lowland soilchemical nonequilibrium modelconvection-dispersion equation AcknowledgmentsWe thank Dr. Takeo Shima (Kyushu-Okinawa Agricultural Research Center, National Agriculture and Food Research Organization) for providing us with soil samples.
