This study aimed at the potential of microbes to utilize carbon substrates embedded in the rhizosphere soil thereby contributing to the healthy nature of the tomato plants. The potential soil physiochemical features and utilization of carbon substrate by soil microorganisms as a result of their respiration to reveal their functions in the ecosystem were evaluated. The soil samples were amassed from the healthy tomato plant rhizosphere, diseased tomatoes, and bulk soil in this study. The physiochemical features and carbon substrate utilization in the bulk soil samples, and rhizosphere samples of powdery diseased, and healthy tomato plants were assessed. The MicroRespTM procedure was used to determine the community-level physiological profiles (CLPP) employing fifteen (15) carbon (C) substrates selected based on their importance to microbial communities embedded in the soil samples. Our results revealed that various physiochemical properties, moisture content, water retention, and C substrates including sugar, amino acid, and carboxylic acid were greater in HR and the substrates were not significantly different ( p < 0.05). The study reveals higher soil respiration in HR as a result of the microbial communities inhabiting HR utilizing more of the C-substrates. This investigation contributes to the tomato plant's healthy state as the microbial communities utilized carbon substrate compared to DR after employing the CLPP assays.","PeriodicalId":49023,"journal":{"name":"Journal of Soil Science and Plant Nutrition","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135093618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was conducted in a greenhouse for 120 days. Dolomite lime was applied superficially without incorporation, individually or in co-application with commercial compost or corn straw-derived biochar. Soil samples were collected at four depths (0–10, 10–20, 20–30, and 30–40 cm). Subsequently, pH, electrical conductivity, and dissolved organic carbon were measured. Bioavailable Cd and geochemical fractionation of Cd were measured at each soil depth. Root- and leaf-Cd concentrations in cacao seedlings were also determined. The results illustrate that the application of either compost or biochar has a pronounced impact on enhancing the mobility of dolomite lime within the soil (up to 40 cm). Notably, heightened alkalinity penetration was observed when dolomite lime and biochar were jointly applied. Concurrently applying biochar with dolomite lime led to a significant elevation in soil pH and a marked reduction in the concentration of bioavailable Cd. Furthermore, the concentration of leaf-Cd underwent a reduction exceeding 50% (± 2%) due to the application of dolomite lime and biochar. Potential mechanisms connected to Cd immobilization may encompass ion exchange and the formation of co-precipitates. Overall, the simultaneous use of dolomite lime and biochar was effective in decreasing Cd concentrations in cacao seedlings.","PeriodicalId":49023,"journal":{"name":"Journal of Soil Science and Plant Nutrition","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135094655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, soybean root growth in sandy and loess soil was evaluated to understand the impact of site and soybean variety characteristics on soybean N uptake under continental conditions in Central Europe. Root analysis to determine rooting depth and root length density (RLD) was carried out using the profile wall method at three growth stages and two soybean cultivars ( Glycine max (L.) Merr. cvs. Merlin and Sultana) in three consecutive years at two locations in eastern Germany. Fertiliser-derived N uptake of soybean from the soil surface and the subsoil was determined at 0.3 and 0.6 m depths using 15 N-labelled nitrate N. Root studies showed that soybean roots grew up to 1.4 m on sandy and loess soil sites. Root length densities of up to 2.4 cm cm −3 were documented in the topsoil. By means of 15 N application, soybean was shown to take up 15% of the surface-applied nitrogen in the dry growing season and 67 % in high rainfall years, between 19 and 77 % of the nitrogen placed at 0.3 m soil depth, and between 2 and 64 % of the nitrogen placed at 0.6 m soil depth by flowering. The field trials showed that soybeans can absorb a high proportion of the nitrogen placed in the subsoil by flowering time. Due to a well-developed root system reaching deep into the soil, soybeans are able to cover their N demand from soil-borne sources and secure yield formation during dry periods by water uptake from the subsoil.","PeriodicalId":49023,"journal":{"name":"Journal of Soil Science and Plant Nutrition","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135829589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
