Furthermore, combined effects of biochar addition and temperature on CO2 production are still unknown. To address this gap, a series of incubation experiments were conducted to examine the single and interactive effects of biochar addition with three particle sizes (1–0.5 mm, 0.5–0.1 mm, and <0.1 mm) and temperature on CO2 production in a temperate forest, China. The soil samples were collected from a poplar (Populus nigra) forest in the sandy area of the ancient Yellow River in western Shandong Province, China. Cumulative CO2 production of fine-grained biochar addition (<0.1 mm) was 88.13–92.67% of that of coarse-grained biochar (1–0.5 mm). The addition of fine-grained biochar decreased CO2 production by reducing soil nitrogen availability (i.e., nitrate and ammonium) and increasing soil pH compared to the coarse-grained biochar. Biochar addition promoted the temperature sensitivity (Q 10) of CO2 production by increasing the relative abundance of recalcitrant carbon fractions. Interactive effects of biochar addition and increasing temperature was synergistic due to the raising Q 10 value of CO2 production. Our results highlight the importance of particle size of biochar on CO2 production, less particle size of biochar, the less CO2 production. We suggest that the simultaneous effect of biochar addition and temperature on CO2 production may be underestimated basing on their single effects. Our results suggest that <0.1 mm is a threshold value of biochar particle size that is helpful to soil carbon sequestration.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81243560","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}

Straw return can improve soil fertility, but it is unknown whether the physicochemical properties of saline sodic soil can be improved by straw return and whether straw return can improve the productivity of saline sodic land. Therefore, we conducted a 4-year field trial to assess the effects of adding straw at 0, 2800, 4200, 5600, and 7000 kg ha−1 (CK, S1, S2, S3, and S4) on the soil physical properties, soil chemical properties, soil nutrients, and rice yield in saline sodic lands from 2017 to 2020. Our results show that a decrease in soil bulk density (BD) and a decrease in the percentage of < 0.053 mm particle size aggregates after straw incorporation depend on the straw incorporation rate. Soil exchangeable Na+ (ENa+) and exchangeable sodium percentage (ESP) were significantly lower in the straw treatments than in the CK treatment, and straw incorporation also had a positive effect on the reduction of soil pH and EC. Straw incorporation had a positive effect on the accumulation of soil organic matter (SOM) and total nitrogen (TN). SOM and TN gradually increased with the increase of straw incorporation rate. Rice yield showed a trend of increasing and then decreasing with the increasing straw incorporation rate, with the highest yield under the S3 treatment at a four-year average yield of 8.57 t ha−1. There was no significant difference between the S3 and S4 treatments in soil physical structure, chemical properties, or nutrients during the experiment. Therefore, we conclude that a reasonable amount of straw incorporation for improving saline sodic soil properties as well as for increasing rice yield in the first four years is 5600 kg ha−1 (S3 treatment).","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77578068","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}

Nitrogen is an indispensable component of fertilizers for producing crops in agricultural soils and is a macronutrient for natural soils driving the food chain, including microbial activities in terrestrial ecosystems. Humans acquired the technology of artificial N fixation during the early 20th century and used the fixed N for fertilizer and industrial materials. Artificial N fixations have amounted to ca. 150 Tg N yr–1 in recent years, surpassing terrestrial biological N fixation. Consequently, a large amount of reactive N (N compounds other than dinitrogen) is lost to the environment, inducing various forms of N pollution and threatening human and environmental health. This review aims to highlight future research on N cycling and management from the soil science perspective based on the author’s experience. The review covers the following themes: N processes to be elucidated preferentially in agricultural soils, interactions between soil and N cycling in the polar regions storing a large amount of organic matter and susceptible to climate change, and N management at national and international scales focusing on how soils are treated.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82675896","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}

Low-phytic acid (LP) crops improve mineral bioavailability in monogastric animals, which can decrease environmental pollution due to phosphorus. Recently, we reported a newly developed LP soybean line by crossing the LP line CX1834 and Japanese normal phytic acid cultivar Natto-kotsubu (Natto), which showed superior traits in seedling emergence, growth, and yield compared with CX1834. The molecular mechanism underlying the LP trait in the LP line remains unclear. The LP line was used for a de novo RNA-Seq analysis, and we illustrated the aberrant RNA splicing of the phytic acid synthase gene inositol-1,3,4 trisphosphate 5/6-kinase 3 (GmITPK3) in the LP line. The expression level of phytic acid biosynthesis-related genes and inositol phosphate isomer concentrations were investigated. A de novo RNA-Seq analysis revealed that the intron retention (IR) transcript of GmITPK3 is highly expressed in the leaves of the LP line. Although expressed in both, the relative abundances of multiple IR transcripts were significantly higher in the LP line than that in the Natto cultivar. The IR transcripts of GmITPK3 encoding truncated proteins were missing an essential domain for their activity, while one possibly contained an abnormal ligand binding site. The relative abundance of IR transcripts was 1.9- to 5.4-times higher in the LP line than that in the Natto cultivar during seed development; accordingly, the production of phytic acid and its precursors in the developing seeds was lower in the LP line than that in the Natto cultivar. No mutation was detected at the exon–intron junction, where a splicing error occurs in GmITPK3 of the LP line, implying that a splicing error is attributed to unknown splicing factor genes involved in the splicing regulation of GmITPK3. Our results provide insights into the possible involvement of splicing errors in GmITPK3 for the trait of low phytic acid production in the LP line.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83414171","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}

A widely practiced countermeasure is the application of K. Long-term maintenance of soil K is crucial due to the long physical half-life of 137Cs (30 years). Plant-available K budgets can be used as an indication of sustainable maintenance. Our previous study found that large water outflow, especially percolation, associated with excessive irrigation caused major K outflow and a negative K budget in a paddy field in Fukushima in 2018. The present study evaluated whether decreasing the water outflow by reducing the irrigation volume from 6300 to 1900 mm reduced K outflow and improved the K budget in the field during the cropping period in 2019. K concentrations in soil solution were comparable in both years, and the percolation water volume decreased to 37% that of 2018, resulting in a 53% reduction in the K output from 392 to 184 kg ha–1. The input via irrigation also decreased (−35 kg ha–1), but the output via surface runoff showed a greater reduction (−58 kg ha–1) owing to a 70% decrease in the water volume compared with 2018. Consequently, the K budget was substantially improved (from −289 to −57 kg ha–1), highlighting the importance of controlling water outflow, particularly percolation, for soil K maintenance in paddy fields with high permeability.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88028601","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}

Water management, however, is considered a burden for farmers, and thus an efficient strategy by which to decrease As and Cd concentrations in brown rice is desired. The purpose of this study was to estimate the effects of water management on the total As and Cd concentrations in brown rice during the 3 weeks before and after heading on a weekly basis. Moreover, the study aimed to determine the differences in this effect among soil types and cultivars. Pot cultivation experiments of rice were conducted by applying two levels of weekly flooding or draining to an L12 orthogonal table, and their effects each week on the As and Cd concentrations in brown rice were identified. Redox potentials of soils decreased during flooding and increased during draining, but the decrease during flooding in Andosols was slower than that in Fluvisols. For the plants growing in Fluvisols, the total As and Cd concentrations in the brown rice increased and decreased with flooding, respectively, and an opposite trend was observed with draining. In the Japonica varieties ‘Koshihikari’ and ‘Hitomebore,’ water management during the first week from 0 to 2 days after heading had the greatest impact on As and Cd concentrations. However, in the Indica variety ‘Takanari,’ the weeks that most affected the As and Cd concentrations were the second and first week from the day after heading, respectively. In the Andosols, the Cd concentration was changed by water management as in the Fluvisols, but the same was not found for the As. This suggests that the effect of water management on the As concentration in brown rice could be nullified by the Andosols ability to absorb As. However, it was also possible that the effect of water management could not be detected due to the low As concentration of the Andosols. These results provide insights that will help to efficiently reduce As and Cd concentrations using information on the rice variety and soil type.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79427105","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}

Although the molecular mechanisms to overcome N deficiency have been intensively studied, the acclimation of photosynthetic apparatus to Fe deficiency in higher plants remains to be further investigated. We previously reported about effective strategies in the chloroplasts of an Fe-deficiency-tolerant crop, barley, which allow photosynthesis under Fe-deficient conditions, not relying solely on Fe acquisition via the roots. The Fe-deficient barley leaves employ at least two strategies, viz., induction of thermal dissipation of absorbed light energy via Lhcb1 phosphorylation, which is maintained stably over Fe-deficiency periods regardless of light conditions, and improved electron flow in or around photosystem I through protein complexes with unknown composition. Previous studies have focused on healthy leaves from which chloroplasts can easily be isolated or on model organisms, such as Arabidopsis and cyanobacteria, to demonstrate typical photosystem structures and photochemical reactions. By contrast, in non-model plants, atypical photosystem structures and compositions have been reported. These structures are generally important to adapt to stress conditions or specific niches. In this review, we elucidate the mechanisms of acclimation of barley photosystems to Fe deficiency and provide an overview of the modulations in the photosystems of other plants under various stress conditions.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91271027","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}

We cultivated plants in rhizoboxes with P-deficient soil for 33 days. We then harvested roots and the adjacent soil from 128 compartments by dividing 2 × 2 cm squares in the rhizoboxes. We investigated relative expression levels of several genes that encode proteins assumed to be involved in P solubilization or translocation. Additionally, we analyzed fractionated P, soluble metal cations (Fe, Al, and Mn), and enzyme activities in the soil of each compartment. We observed a significant positive correlation between one of the MATE (multidrug and toxic compound extrusion/detoxification) genes, LaMATE6, and soluble metal cations, suggesting the secretion of citric acid into the rhizosphere via MATE proteins increased soluble metal cation concentrations. Furthermore, we demonstrated that roots in the same developmental stages were likely to have different influences on the mobilization of fractionated P in the rhizosphere soil. Our findings highlight the importance of investigating the relationship between soil chemical properties and root functions at a high spatial resolution to elucidate the detailed mechanisms of P mobilization by plants.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82175026","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}

In the present study, we confirmed that S fertilization increased secretion of organic acids such as citric acid when soybeans were cultivated in Andosols having a strong P fixation capacity. In contrast, concentration of citric acid in soybean roots did not increase by S fertilization. Therefore, the relationship between S nutrition and gene expression of citric acid exporters was investigated to understand the mechanisms of induction of citric acid secretion by S. Further, we verified whether the expression of citric acid transporter genes, GmMATE13 and GmMATE47, is involved in the induction of citric acid secretion from the roots by S fertilization. The expression level of GmMATE13 in roots was significantly increased by S fertilization compared to that without S fertilization. Therefore, our results suggest that S nutrition is involved in inducing GmMATE13 expression and contributes to the excretion of citric acid from the soybean roots.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87992559","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}

Several soil samples have been traditionally assumed to be sufficient for soil tests to represent field-specific values in conventional Japanese small-scale paddy fields. However, rethinking soil sampling design is required, as many small-scale (<0.3 ha) paddy fields have been consolidated into large-scale (>1 ha) paddy fields to enhance the efficiency of crop production. The purpose of this study is to explore an efficient soil sampling design, including sample size for representing field-specific values and sampling distance for representing spatial variations, in central Japan using bootstrap sampling and geostatistical analysis. Fourteen soil properties were quantified from 553 samples, which was collected at a distance of 24.4 m on average in large-scale paddy fields with continuous rice cultivation and rotation of rice and upland crops (winter wheat and soybean). The results show that the conventional sampling size (n = 3 for each field) achieved mean estimation within 10% error with 95% confidence intervals only for pH and sand content in almost all fields; thus, an optimization of field-specific uniform liming rate is recommended for reducing cost. Geostatistical analysis shows that the recommended soil sampling distance should be 15–163 m, depending on specific soil properties. The results further show that it was difficult to obtain reliable estimates of exchangeable K and mineralizable N because of the high level of spatial uncertainty with high nugget variance. Thus, practitioners should note that the outcomes from soil tests inherently included fine-scale errors in available nutrient levels which may preclude rationale prescriptions. This study demonstrated that appropriate soil sampling design and the subsequent soil management can differ depending on specific soil properties in the actual farming scale of large-scale paddy fields.","PeriodicalId":21852,"journal":{"name":"Soil Science and Plant Nutrition","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81489631","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}
