It is the essential predictor used in most predictive programs for predicting water flux, solute, and heat transport in soil. Predictive programs such as Rosetta, RETC, and HYDRUS-1D are usually used PSD measured by the pipette method (PM), whereas the usage of PSD measured by laser diffraction technique (LDT) yields a large estimation error in heavy soil. The aim of the work was to optimize PSD measured by LDT for approaching to PSD measured by PM by suggesting Pedotransfer functions (PTFs). Furthermore, it is to evaluate the efficiency of PSD calculated by the proposed PTFs for estimating soil hydraulic properties using Rosetta program. Particle size distribution was measured by two methods: LDT and PM using the same dispersion factor (sodium pyrophosphate solution 4%). Proposed PTFs were derived for calculation of particle size distribution using a linear regression between PSD measured by LDT as an independent variable and PSD measured by PM as a dependent variable. PSD calculated using proposed PTFs leads to optimize values of PSD measured by LDT for approaching to values of PSD measured by PM. Optimizing PSD by proposed PTFs was suitable for calculating soil hydraulic parameters using Rosetta program with a little estimation error, for agro-soddy podzolic with soil texture as silty loam and silty clay loam.","PeriodicalId":294623,"journal":{"name":"Soil in the Environment","volume":"44 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132152054","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}

One way to overcome this problem is to use wastewaters for irrigation. To determine the effect of salinity and sodicity of municipal wastewater as irrigation water and leaching application, on some of common soil chemical properties and consequently on growth performance of corn, a soil column experiment was conducted with sandy clay loam soil. Nine treatments including wastewaters with three different salinity levels: 1, 4.7 (blending of 1 and 9 dS/m wastewaters with 1:1 ratio), 9 dS/m, and three levels of leaching fractions: 0, 15 and 30 percent were arranged in a factorial experiment with three replication. Results show that at first and last layer of the soil, the effect of 30 percent leaching on soil salinity (ECe) was statistically significant only for irrigation with 9 dS/m wastewater. Application of the 15 and 30 percent leaching fraction for irrigation with 4.7 dS/m wastewater (SAR = 8.2) significantly reduced soil SAR at first layer of the soil. The application 30 percent leaching fraction significantly increased corn dry yield for irrigation with all of three wastewaters. There was no significant difference between effects of irrigation with 4.7 dS/m wastewater with the 15 and 30 percent leaching fraction and irrigation with 1 dS/m wastewater with 0 and 15 percent leaching fraction on IWUE. Results show that with combination of leaching method and reduction wastewater salinity through blending of wastewaters for irrigation with saline sodic wastewater, high corn biomass can be achieved, without any significant difference in comparison with non-saline or non-sodic wastewater.","PeriodicalId":294623,"journal":{"name":"Soil in the Environment","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127954201","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}

Among the many agrochemicals used, glyphosate-based herbicides raised controversy, encouraging research to clarify if the benefits of their use outweigh their alleged harmfulness. In this spirit, this study assessed soil quality indicators on glyphosate-sprayed fields under natural (NC) and zero tillage conditions (ZT) in Northwest Argentina, to analyze the effect of the herbicide application on soil degradation. The ZT soils underwent five years of continuous spraying (2-4 times a year) after land clearing, while the NC soil, without any laboring practices, was subjected to two consecutive applications. Among the measured indicators (physical, chemical, and biological), water-stable aggregates (WSA), particulate organic matter (POM) and dehydrogenase activity (DHA) showed quality differences between ZT and NC samples. The highest values were found in NC (WSA 72%; POM 4.9%; DHA 1460 mg TPF/g soil /d) and the lowest in ZT (WSA 13%; POM 1.69%; DHA 180 mg TPF/g soil /d); showing a lower quality in ZT regarding structure stability, nutrient availability and microbial activity. A Discriminant Analysis revealed that as glyphosate application increased, the overall soil quality decreased within the NC samples, resembling that of ZT. Thus, soil health deterioration was attributed solely to glyphosate spraying in NC. Furthermore, multivariate analysis allowed identification of chemical indicators as of higher sensitivity to the short-term response after application, and biological indicators as more sensitive to long-term changes. The quality decline in time in the NC soil, caused by the use of glyphosate-based herbicides, could endanger the soils sustainability.","PeriodicalId":294623,"journal":{"name":"Soil in the Environment","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126434073","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 experiment was arranged in completely randomized design with three replications. Results demonstrated significantly higher plant height, root/ spike length, shoot/ root dry weight, number of tillers/ spikelets/ grains, 1000 grain weight, grain/ straw/ biological yield, nitrogen/ phosphorus/ potassium concentrations of shoot and grain due to inoculation with W6 or W10 alone or in combination as compared to no inoculation. Carriers significantly lowered the spike length, root dry weight, grain number, biological/ grain/ straw yield, nitrogen/ phosphorus/ potassium concentration in shoot and nitrogen concentration in grains as compared to no carrier (seeds soaked for 1 h). However, peat was statistically at par with no carrier for plant height, root length, shoot dry weight, number of tillers/spikelets, 1000 grain weight, grain phosphorus and potassium concentrations. Combined (W6×W10) inoculation remained most prominent followed by W6 and W10, respectively. Similarly, inoculation without carrier (soaking) remained most efficient from carriers followed by peat as a carrier. Biogas slurry and press mud remained statistically at par with each other but lower than no carrier and peat in all parameters. Keeping in view the results, it can be inferred that combined inoculation without carrier (soaking) is most beneficial but peat can be recommended as best carrier from biogas slurry and press mud.","PeriodicalId":294623,"journal":{"name":"Soil in the Environment","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129198771","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}

Recreational zones create a ‘green frame’ of a city and provide vital functions and services for city dwellers. This research focuses on the comparative analysis of spatial distribution of the key soil properties (acidity, organic carbon and nutrient contents) in the urban park named after Artyom Borovik (Moscow, Russia) before and after reconstruction. The maps of the urban soil’s properties were created for both periods by interpolation of the field data, collected from the depths 0-30, 30-50 and 50-100 cm. The maps of the analyzed properties were developed using open Quantum GIS2.4 software by Inverse Distance Weighting (IDW). High spatial variability was observed for the soil properties with the highest variance reported for nutrient concentrations. High heterogeneity in P2O5 and K2O was obtained both in topsoil and subsoil, before and after reconstruction. We found that average concentrations of P2O5 and K2O were correspondingly above and below legal threshold taken for the Moscow city. As a result of the reconstruction the pH has changed from slightly acid and acidic to neutral and slightly alkaline. The topsoil soil organic carbon (SOC) content has increased in result of reconstruction but still was below threshold, recommended by municipal regulations. The findings of the research can be used to project possible changes in soil cover resulted from expansion and reorganization of green areas, which is essential to support decisions in urban planning and soil management in sustainable cities.","PeriodicalId":294623,"journal":{"name":"Soil in the Environment","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123819845","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}
