In the past few years, there has been interest from research agencies and relevant ministries to control soil degradation in the Egyptian lands. This study aims to assess soil degradation , soil productivity and the correlation coefficient between them in Bilqas District, Dakahlia Governorate. To achieve this goal, soil data for the study area were taken from a previous study (2010) and compared with soil data for the study area at the present time. Two main physiographic units dominate the study area i.e. Aeolian plain (Coarse texture) and Flood plain (Moderately fine to fine texture). Depending on these physiographic units, the study area was divided into different types of landforms, sixteen soil profiles were selected to represent these types of landforms. The soil profile locations examined by the current study were the same as the soil profile locations for the previous study.<br />Soil degradation status was assessed; the results indicate that the most active soil degradation processes are salinity, waterlogging and alkalinity. After evaluating the soil productivity, it was found that its productivity indexes were decreased in most of soil profiles, while it was stable in some profiles and increased in few profiles. There was correlation coefficient between soil productivity and water table level , salinity and alkalinity.https://ejss.journals.ekb.eg/article_191532_2a0d04d2db8f263e73dc8d8fa318b33f.pdfThe National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)Egyptian Journal of Soil Science0302-670161320211101Enhancing Onion Yield, Quality, Storability and Profitability by Using FYM, Copper and Bio-fertilizer32333519839210.21608/ejss.2021.76458.1448ENMohamed GamalSarhanDepartment of soil fertility and plant nutrition; Soil, Water and Environment Res.

Dep., Fac., of Agric., Minia University, EgyptJournal Article20210517This investigation explored the effect of copper application under organic and bio-fertilization on onion growth, yield and yield components, chemical contents and bulb storability as well as economic efficiency during 2018/2019 and 2019/2020. In this research, the design of the experiments was split-split design in complete randomized blocks in four replications. The factors were: A. farmyard manure (0.0, 12 and 24 t ha-1) where arranged in the main plots, B. copper (0.0 and foliar spray of copper sulphate at rate of 0.1% twice, about 600 L ha-1) where randomly allocated in sub plots, and C. biofertilizer (0.0 and inoculation with Azotobacter chroococcum inoculant) where randomly applied in sub- sub plots. The results indicated that increasing FYM levels, foliar spraying of Cu and bio-fertilization improved all studied onion quality and quantity, except copper concentration in onion leaves at 75 days age which affected only by copper application. From the results of this research, it could be recommended to fertilize onion plants with 12 t ha-1 of FYM instead of 24 t ha-1 with Cu spraying and biofertilizer inoculation to maximize the quality, quantity, storability and net return of onion grown in alluvial soil at Middle Egypt conditions.https://ejss.journals.ekb.eg/article_198392_21046f8990e6d70653208bb096e50f0a.pdfThe National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)Egyptian Journal of Soil Science0302-670161320211101Evaluation of Heavy Metals Concentration as Affected by Vehicular Emission in Alluvial Soil at Middle Egypt Conditions33735419799210.21608/ejss.2021.89288.1460ENMohamed G.

Dep., Fac., of Agric., Minia University, EgyptJournal Article20210804Road traffic exhaust emissions are one of the most common sources of contaminants to soils and vegetation lies in the vicinity of highways. The main aim of this research is to investigate concentrations of Pb, Cd, Zn and Cu in soil at surface soil depth (0.0 – 30) and subsurface soil depth (30 – 60 cm) as affected by vehicle exhausts along the agricultural highway connecting Cairo – El-Minia City across Beba City, Beni-Suef Governorate, Egypt. In addition, revising the consequences on the staple wheat and maize roadside crops in terms of heavy metals presence in the edible parts for animals and humans. The results show that as the distance from the road decreased the concentration of Pb, Cd and Zn increased to 22, 45, 67, in soils and to 34, 56, 67 in plants, respectively. In general, the limits of heavy metals in wheat and maize plants were safe as stated by WHO (World Health Organization), except Cd (34) in leaves of wheat and maize grown adjacent the road. The pollution incidences, namely, transfer factor (TF), single pollution index (PI) and index of geo-accumulation (Igeo) were calculated and the results indicate that these indices decreased as the distance from the road increased especially in the western side rather than the eastern one. In this concern, this soil was moderately contaminated with Cd, while Pb, Zn and Cu were in the safety level. In conclusion, wheat and corn leaves contain cadmium near the danger limit, so it can be concluded that feeding animals should be prevented by plants grown near highways.https://ejss.journals.ekb.eg/article_197992_bfd3870c516e890a5ca897bbacfc49aa.pdfThe National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)Egyptian Journal of Soil Science0302-670161320211101Integrated Management of K -Additives to Improve the Productivity of Zucchini Plants Grown on a Poor Fertile Sandy Soil35536520092510.21608/ejss.2021.99643.1472ENMonaTolbaPlant Nutrition Department, National Research Centre, Dokki, Giza, Egypt0000-0001-6499-2609Ihab MFaridBenha University, Faculty of Agriculture, Soils and Water DepartmentHananSiamPlant Nutrition Department, National Research Centre, Dokki, Giza, EgyptMohamed H.H.AbbasBenha University, Faculty of Agriculture, Soils and Water department0000-0002-1905-1241IbrahimMohamedSoils and Water, Faculty of Agric., Benha UniversitySafaaMahmoudPlant Nutrition Department, National Research Centre, Dokki, Giza, EgyptAbo El-KairEl-SayedAlgal Biotechnology Unit, Fertilization Technology Department, National Research Centre, Dokki-Cairo, EgyptJournal Article20211005Three eco-friendly approaches were investigated for their effects on improving K-uptake by zucchini plants; hence, increasing shoot growth and fruit productivity. These approaches were: (1) amending soil with biochar (0 and 5g kg-1), (2) spraying plants with Amphora extract (0 and 1g L-1) and (3) substituting inorganic-K fertilizers partially with organic ones. In this concern, five levels of compost (0, 1.5, 3, 4.5 and 6 g kg-1) were applied to a poor fertile sandy soil (98.5% sand) in complementation with inorganic NPK-fertilizers to bring their concentrations, even in the control treatment, to the recommended levels. This investigation was conducted under the greenhouse conditions during the summer season of 2020. Results obtained herein reveal that application of either of biochar or Amphora extract exhibited positive effects on soil available-K (20 and 6.5% respectively), K-concentrations in fruits and total K-uptake by the aboveground plant parts. Furthermore, these two amendments raised considerably the dry weights of both zucchini shoots and fruits. On the other hand, compost could partially substitute inorganic-K fertilizers when it was applied at a rate not exceeding 3g kg-1, recording significant improvements in all the investigated parameters. Nevertheless application of high compost doses reduced significantly fruit yield. Generally, there existed a highly significant linear relation between the total K-uptake by plants and fruit dry weights. Accordingly, treatments that improved considerably K-uptake by plants (the combination between foliar application of amphora extract + 5 g kg-1 biochar + 0-3 g kg-1 compost) recorded the highest improvements in productivity of zucchini plants.https://ejss.journals.ekb.eg/article_200925_e342b2a664b77c3a3a681180ceb3831f.pdfThe National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)Egyptian Journal of Soil Science0302-670161320211101Optimizing Roots and Sugar Yields and Water Use Efficiency of Different Sugar Beet Varieties Grown Under Upper Egypt Conditions Using Deficit Irrigation and Harvesting Dates36737220789610.21608/ejss.2021.105612.1476ENOMARYASSINSoils and Water Inst., Agric.

A split split block design with three replications was used. Main blokes were assigned to three irrigation water regimes (100%, 85%, and 70% of water requirement). The sub blots were occupied by three harvesting dates (180, 195 and 210 days). Sub- sub plots were comprised three sugar beet varieties namely (RAVEL, SV1841and SA1686).<br />Results indicated that reducing water supply reduced roots, sugar and biomass yields but increased water use efficiency (WUE). Increasing harvesting date increased roots and sugar yields but reduced biomass yield. Roots, sugar and biomass yields of RAVEL and SA1686 varieties were almost comparable but higher than those of SV1841 variety. The highest sugar WUE was obtained from SA1686 at 70% WR treatment under 210 days harvesting date followed by RAVEL variety at 70 % WR and 210 day harvesting date. Results clarified that cultivating either RAVEL or SA1686 variety with 70% of water requirement and for 210 growing days under Upper Egypt conditions optimized roots and sugar yields and WUE of sugar beets.https://ejss.journals.ekb.eg/article_207896_f30327ecd48e84975873261e6556ac3d.pdfThe National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)Egyptian Journal of Soil Science0302-670161320211101Nanofibers for Sustainable Agriculture: A Short Communication37338020950410.21608/ejss.2021.105877.1477ENKhandsurenBadgarInstitute of Animal Science, Biotechnology and Nature Conservation, Faculty of Agricultural and Food Sciences and Environmental Management, University of Debrecen, 138 Böszörményi Street, 4032 Debrecen, HungaryJoeProkischInstitute of Animal Science, Biotechnology and Nature Conservation, Faculty of Agricultural and Food Sciences and Environmental Management, University of Debrecen, 138 Böszörményi Street, 4032 Debrecen, HungaryHassanEl-Ramadysoil and water dept. faculty of agriculture0000-0002-1113-726XJournal Article20211113Nanofibers could be defined as the fibers which have their diameters in nanometric range. These nanofibers have applied to many fields including the biomedical, pharmaceutical, environmental, and agricultural sectors. The previous fields have increased demand for eco-biodegradable sustainable materials that can use with high superior physical and mechanical properties like nanofibers. The medicinal and pharmaceutical fields have more attractive forces for investment compared to agriculture, which its investments in field of nanofibers still need more efforts. Concerning the agricultural field, nanofibers have been used for coating seeds, for plant protection, for encapsulation of agrochemicals, and for the filtration in irrigation systems. On the other hand, many applications of nanofibers in the environment could be adapted including air and water filtration, environmental sensing, water/wastewater treatment, heavy metal removing, for cosmeceutical purposes, and for antimicrobial treatment. However, more research should be undertaken to investigate different aspects of nanofibers on the agro-environment. There are still many unanswered questions about the impacts of nanofibers on soil biology and its quality. Further work is also required to establish the standardization of nanofiber-amendment for soil and water conservation in frame of sustainable development.https://ejss.journals.ekb.eg/article_209504_4df4d9a43d279369bb2b3afd32e352fb.pdfThe National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)Egyptian Journal of Soil Science0302-670161320211101Edible Mushroom Cultivated in Polluted Soils and its Potential Risks on Human Health: A short communication38138920950510.21608/ejss.2021.106452.1478ENHassanEl-Ramadysoil and water dept. faculty of agriculture0000-0002-1113-726XXhensilaLlanajInstitute of Animal Science, Biotechnology and Nature Conservation, Faculty of Agricultural and Food Sciences and Environmental Management, University of Debrecen, 138 Böszörményi Street, 4032 Debrecen, HungaryJoeProkischInstitute of Animal Science, Biotechnology and Nature Conservation, Faculty of Agricultural and Food Sciences and Environmental Management, University of Debrecen, 138 B&ouml;sz&ouml;rm&eacute;nyi Street, 4032 Debrecen, HungaryJournal Article20211116Edible mushrooms are considered an important source for the human nutrition nowadays because of their high contents of bioactive compounds (e.g., vitamins, proteins, terpenoids, phenolic compounds, lipids, and polysaccharides). These active ingredients are crucial source for many industries particularly the pharmaceutical and therapeutic fields as well as functional foods. This manuscript focuses on what we called mushrooms and their nutritional profiles, edible mushrooms and their common species, therapeutic applications of edible mushrooms. The potential risks of edible mushrooms for human health were also discussed. Cultivated edible mushrooms in polluted soils may represent a serious potential risk on human health. The harvested edible mushrooms from polluted soils may have a high heavy metal content or other toxic metals or organic polluted or radioactives, which could threaten the human health causing several diseases. The sustainable solutions for producing safe edible mushrooms for human nutrition under different growth conditions are of interest global issue due to edible mushrooms are established as one of he most important sources of human foods.https://ejss.journals.ekb.eg/article_209505_bf9cd40bbdf30f4c3fb764066937ad05.pdf
