The COVID-19 may have long-lasting impacts on the environment health, biodiversity, and soil security, consequently, will raising several scientific questions to be investigated in near future including the expected environmental impacts of COVID-19 on soil, water and air, connecting the missing links between environmental pollutions and COVID-19. Most importantly, unraveling the role of soil in spreading or reducing transmission of the COVID-19 pandemic, and soil xenobiotics status under the COVID-19 outbreak. Understanding the projected management scenario of soil and freshwater pollution in the post-COVID-19 era and the potential impact of COVID-19 on food and soil security would be of immense aid in the preparation of future pandemics.

Therefore, four irrigation intervals of 3, 6, 9 and 12 days with four irrigation levels of 100 (Control), 120, 80, and 60% cumulated pan evaporation (CPE) were tested. Results showed that irrigation scheduling significantly influenced the stated items. The mean seasonal irrigation water for the highest economical yield of fresh weight of spike was 12.58 cm, while it was 14.05 cm for new corm under 9 days and 60% or 12 days and 80%, respectively with mean value of 13.32cm. Regarding irrigation water productivity (IWP), the stated irrigation scheduling gave the highest IWP for spike (0.7g.cm-1) and new corm of 0.43 g.cm-1. For freesia marketable yield of fresh weight of spike and new corm, maximum spike weight was obtained from 9 days and 60% and for fresh weight of new corm was obtained from 12 days and 80% CPE. By applying 12 days and 120% level, the highest values of plant height, number of leaves per plant and weight of fresh and dry vegetative growth were recorded. Whereas, 3 days and 120% level gave the highest leaf area. Moreover, watering each 9 days and 80% CPE is the effective irrigation scheduling on flowering parameters. Meanwhile, 12 days and 60% is the proper irrigation scheduling for highest total chlorophyll content.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74367093","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}

To assess the status of some trace-elements (As, Co Cd, Pb, Cu and Ni) in the North-East area of Egypt, well-water samples beside of surface, subsurface and deep-soil-samples were collected from 17 different locations to represent three environmental-pathways: the first one signifies areas relatively nearby Damietta-branch, while the third pathway stands for the arable lands nearby Ismaellia-canal. The second pathway is in-between these two pathways. Furthermore, a reference soil (irrigated with fresh-Nile-water) was sampled for data comparison. These samples were estimated for their total and AB-DTPA-extractable contents of the aforementioned trace elements (TEs). Results revealed that AB-DTPA-extractable-TEs were in dynamic equilibrium with the corresponding soluble contents in irrigation water. Likewise, AB-DTPA-extractable-TEs significantly correlated with their corresponding total contents in soil. Concentrations of TEs in surface-soil-layer were higher than the corresponding ones in the subsurface and deep-soil-layers. The calculated values of contamination factor indicated moderate to very high levels of soil contamination with TEs. According to principal component analysis, total and AB-DTPA-extractable-TEs in soil were affected by only one-principal-component, recording 86.13 % of the data variance. This indicates that these contaminants originated probably from the same source. Moreover, multivariate-analyses revealed that total TEs significantly and positively correlated with soil hydraulic conductivity and bulk density, while negatively correlated with exchangeable sodium percentage, clay and organic matter contents. These results indicate that the groundwater flow is the potential source that enriched soils with TEs.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78155761","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 proper nutrition of cultivated plants in its time, source, amount, and place is the guarantee for this satisfied production. Therefore, the science of plant nutrition is an increasingly important area in plant sciences, which has direct and indirect link with human health. The concept of plant nutrition has been changed from investigation of the application, translocation and metabolism of nutrients by plants into the \"engineering\" of these applied nutrients for human health. So, it has been established that \"feed the soil to feed the human\". Thus, recent developments in the field of plant nutrition have led to a renewed interest in the relationship between plant nutrition and human health. Therefore, this is an introduction to highlight on the new book series \"Sustainable Plant Nutrition under a Changing World\", which will be published by Springer Nature. This book series will focus on advance issues in plant nutrition under stressful environments starting with the changing in global climate and reaching to the production of cultivated crops biofortified with desirable nutrients like iodine, and selenium.","PeriodicalId":11727,"journal":{"name":"Environment, Biodiversity and Soil Security","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72998280","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}

Therefore, preserving the availability and quality of this resource is enormously important. Water quality is affected by a number of factors related to the characteristics of the watercourse and surrounding environment, like soil type, agricultural and industrial activity in the studied regions. Therefore, a comparative study was conducted on water samples collected from eight different locations at west and middle Delta regions from Beheira and Gharbia governorates. The obtained results showed that there are significant differences among the means of sample collection sites and dates, as well as the interaction between studied variables in all studied parameters. Although, most physical and chemical parameters were within standards limits except turbidity and chemical oxygen demand (COD). However, the average values of turbidity, color and pH were convergent in both governorates. While total dissolved salts (TSS) had a higher value (42.2 mg L-1) in the Beheira governorate. In the case of, the remaining studied parameters, the values recorded in Gharbia gov. were higher than the corresponding values recorded in Beheira gov. including COD and UV245 absorbance, which are associated with organic pollution.
