Allah created everything in this universe, from humans (Man) to animals, plants, soils, air, water, etc., where everything was made or created from water. Concerning the creation of humans, Allah created or made all things in an excellent phase and the first step of human creation was fashioned from clay. These steps include the creation of Man from spurting water, a drop of semen, the sperm fashioned into an embryo, this embryo fashioned into a shapeless lump of flesh, then from the lump of flesh, fashioned bones, then clothed the bones with flesh and then created the consanguinity and affinity. So, a very strong link between soil and human health has been reported and the great roles of soils in plant and human nutrition have also have been established. On the other hand, the effect of pollution of soils and their security on human health should be considered. Therefore, this review is an attempt to emphasize the great roles of soils in human creation and health as well as the security of soils under pollution conditions.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Impact of Green Manure, Mineral and Bio Fertilizers on Soil Fertility, Onion-maize Productivity and N-use Efficiency11282753410.21608/jenvbs.2019.7507.1051ENKholoudEl-NaqmeSoils, Water and Environment Res.

Center, Giza, Egypt.Journal Article20190122SOIL fertility was and still one of the most important factors controlling the productivity of crops. A field experiment was conducted at Sakha Agricultural Research Station, Egypt to assess the effect of green manure, bio-N fertilizer and mineral nitrogen fertilizer on some soil properties, mineral nitrogen fertilizer efficiency (i.e., N-use efficiency) and yield of onion (in winter season 2015/2016) following by maize (in summer 2016). Treatments included bio-N-fertilizers, mineral nitrogen fertilizer and green manure. The results showed that using all green manures (i.e., Egyptian clover and fenugreek) before planting onion significantly developed soil properties; increased availability of the studied nutrients and total porosity. Inoculations with bio-fertilizer maximize these effects on soil properties and yield of onion and maize. Interaction between fenugreek with bio-fertilizer and mineral N-fertilizer at 120 kg fed-1 attained the highest values of total onion yield, averages of bulb weight, diameter, dry matter content and nutrients-uptake of NPK in the first season after green manure application. After cultivation of maize, the highest values of grain and dry stalks yields, 100-grain weight and NPK-uptake were obtained with the interaction of Egyptian clover with bio-fertilizer and N-fertilizer at 90 kg fed-1. The use of Egyptian clover as green manure with bio-fertilizer increased N-use efficiency for onion at 60 kg N fed-1 and for maize grain yield was at 120 kg N fed-1. So, the study concluded importance of using green manures to improve soil properties and use efficiency of mineral nitrogen fertilizer.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Nanoparticles: A Novel Approach for Sustainable Agro-productivity29622828310.21608/jenvbs.2019.7478.1050ENAlaa El-DeinOmaraAgriculture Microbiology Dept., Soil, Water and Environment Research Institute (SWERI), Sakha Agricultural Research Station, Agriculture Research Center (ARC), Egypt0000-0001-5622-7501TamerElsakhawyAgriculture Microbiology Dept., Soil, Water and Environment Research Institute (SWERI), Sakha Agricultural Research Station, Agriculture Research Center (ARC), EgyptTarekAlshaalSoil and Water Dept., Kafrelsheikh Uni.HassanEl-RamadySoil and Water Dept., Faculty of Agriculture, Kafrelsheikh Univ, Egypt.ZoltánKovácsAgricultural Botanics, Plant Physiology and Biotechnology Department, University of

On the other hand, the highest total seed yield of cowpea was recorded from use the co-inoculation with 9 ton ton/fed which was 0.679 and 0.682 (ton fed-1) for seed yield and 0.316, 0.324 (ton fed-1) for straw yield during 2015 and 2016 seasons, respectively. <br /> Consequently, it is to recommend that mixture inoculate with Bradyrhizobium sp. and Azospirillum brasilense and addition of 9 ton fed.-1 bentonite could be improving crop growth of cowpea and improve sandy soil fertility.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Monitoring Water Quality of some Canals in Delta Region, Egypt73953029310.21608/jenvbs.2019.11428.1057ENSabry AbdElMonemAbdAllahFaculty of Agriculture, Sibirbay Campus, Mahalat Menouf Rd, Tanta, Gharbia, Egypt.0000-0003-1425-2711Hassan RagabEl-RamadySoil and Water Department, Faculty of Agriculture, Kafrelsheikh University, Kafr El-Sheikh, Egypt0000-0002-1113-726XAbdelhakeem E.El-SherbeniPlant protection dept., Faculty of Agriculture, Tanta University, Tanta, Egypt.Helmy A.AnberPlant protection dept., Faculty of Agriculture, Tanta University, Tanta, EgyptElsayed A.KeshkPlant protection dept., Faculty of Agriculture, Tanta University, Tanta, EgyptSobhyHamedPlant protection dept., Faculty of Agriculture, Tanta University, Tanta, EgyptHazem M.AminePlant protection dept., Faculty of Agriculture, Tanta University, Tanta, EgyptJournal Article20190403Egypt suffers from the scarcity of water resources. The problem has been exacerbated by the steady increase in population density and the establishment of the Grand Ethiopian Renaissance Dam. 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. Thus, physical and chemical approaches can be used to evaluate the water quality in relevant locations. Further studies based on biological approaches should be also carried out.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Effect of Microbial Inoculation and Mineral Amendments on Improving Compost Quality971073762510.21608/jenvbs.2019.12225.1059ENSheblA.

Eight rice genotypes namely; Sakha102, Sakha104, Sakha105, Sakha106, Giza178, A22, IRAT170, and WAB56-125 were evaluated under drought and salinity conditions. Significant genetic variation was found among rice cultivars for seedling vigor under salt and drought stress conditions. Thus, the selection for improved traits among these cultivars would be effective in all traits. The phenotypic coefficient variability (PCV %) was higher than genotypic coefficient variability (GCV %) for the all traits, indicating the existence of wide genetic variability among these genotypes. Under sever salt stress, A22 followed by WAB56-125 were the most tolerant rice genotypes which can be used for cultivation under salt stress conditions. Furthermore, Sakha104 was the best genotype under water deficit for most studied traits followed by IRAT170 and could use to improve the drought tolerance in breeding programs.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Influence of Arbuscular Mycorrhizal (AMF) Inoculation on the Performance of Sakha 107 Rice Cultivar under Different Irrigation Intervals.1191294751310.21608/jenvbs.2019.15637.1068ENSaiedGewailyRice Research &amp; Training Center, Field Crops Research Institute, Agricultural Research Center, Sakha, Kafr El,Sheikh, EgyptJournal Article20190804the experiment was effectuated at the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt in 2017 and 2018 rice growing seasons to determine the performance of Sakha 107 rice cultivar as affected by inoculation of Arbuscular Mycorrhizal fungi (AMF) under different irrigation intervals.

The combined use of mineral fertilizer and bio fertilizer is required so; wheat plants were inoculated with Azospirillum lipoferum strains and/or Anabaena oryza to evaluate plant growth parameters and productivity under salt affected soils. Salt-tolerant A. lipoferum isolates (A10 and A11) have been isolated and identified by 16S rRNA sequencing. Wheat grains were inoculated with A. lipoferum strains and/or A. oryza. Inoculation with A. lipoferum and/or A. oryza increased root length compared with un-inoculated grains. Wheat plants inoculated with bacterial species grown in pots and soil experiments which had different salinity levels that arranged from normal (2.4 dSm-1) to salty (6.9 and 11.4 dSm-1) soils. The activity of enzymes urease and phosphatase in the wheat rhizosphere were determined. A. lipoferum species had the variable microbial count at different salinity levels. In addition, salinity had deleterious effects on the dry weight of plants, the number and dry weight of branches, spikes and grains, total chlorophyll, nitrogen and potassium concentrations. Furthermore, Na% was increased in shoot and grains of wheat plants. Reashiry, inoculation with nitrogen fixed A. lipoferum strains and/or A. oryza enhanced these parameters. Thus, inoculation with the salt-tolerant A. lipoferum strains (A10 and/or A11) and/or A. oryza reduced the deleterious effect of salt stress on wheat plants and enhanced productivity as compared to un-inoculated plants which fertilized with full dose traditional mineral nitrogen.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Productivity of Heavy Clay Soils as Affected by Some Soil Amendments Combined with Irrigation Regime1471625417010.21608/jenvbs.2019.14251.1066ENMahmoud Abou EL-FotuchAiadSWERI, ARC.Journal Article20190702Two field experiments were carried out at Sakha Agricultural Research station, Kafr El-Sheikh governorate during the two growing seasons 2015/2016 and 2016 to investigate the effect of irrigation regimes and soil amendments on some soil properties, some water relations and yields of wheat and maize. The experiments were conducted in strip block design with three replicates. The most important findings can be summarized as follows: <br /> Irrigation at 40% depletion of available soil moisture received the highest amount of irrigation requirements, consumed water and stored water. The highest values of irrigation application efficiency and water consumptive use efficiency were recorded with irrigation treatment at 55% depletion of available soil moisture during two growing seasons. Water productivity (wp) and productivity of irrigation water (PIW), were recorded highest values under (I2) for maize crop. While the highest values of wp and PIW for wheat and maize were achieved from the interaction between irrigation treatment (I2) and soil amendments . The electric conductivity, sodium adsorption ratio, exchangeable sodium percentage were clearly improved and reducing of soil bulk density and increasing soil basic infiltration rate with application of soil amendments. Irrigation treatments and soil amendments have highly significant effect on increasing of yield of wheat and maize. Economic evaluation recorded the highest values of total income, net income, economic efficiency and net income from water unit with application of compost at rate of 5 ton fed-1 under I2 for wheat and maize crops.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Evaluation of Salt-Tolerant Azospirillum lipoferum and Its Role in Improvement of Wheat Growth Parameters1631785539010.21608/jenvbs.2019.16428.1069ENIbrahimEl-AkhdarMicrobiology Department, Soils, Water and Environment Research Institute, ARC, Egypt.MostafaEl-SheekhBotany Department, Faculty of Science, Tanta Univ.

The isolates were cultivated on nitrogen-free malate (NFM) medium supplemented with different NaCl gl-1 concentrations (Zero, 0.7 and 1.5%) and tryptophan to study the salt tolerant in vitro and indol acetic acid production. Pots were used to evaluate the most salt-tolerant and efficient species and soils of this experiment had artificially salinized with different salinity levels. The most salt-tolerant A10 and A11 species were genetically identified by 16S rRNA sequencing and the results revealed to be closest matched at 99% A. lipoferum strains and selected to inoculate wheat plants. The investigated A. lipoferum species had variable divergence growth at different salinity levels. Actually, increased salinity had deleterious effect on IAA production. In addition, salinity had deleterious effect on dry weights of plants, number and dry weight of branches, total chlorophyll, sodium and potassium% with increasing salinity levels. But, inoculation with associative nitrogen fixation A. lipoferum isolates enhanced the previous parameters. Thus, inoculation with the salt-tolerant A.lipoferum isolates decreased the deleterious effect of salt stress on wheat plants.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Quality Assessment of Some Water Sources and Soil under Sea Water Intrusion Conditions in North Nile Delta, Egypt1791926253910.21608/jenvbs.2019.19036.1073ENMohamedEl-GhannamSoils, Water and Environment Research Institute, Agricultural Research Center, Giza, EgyptMona K.Abdel-RazekSoils, Water and Environment Research Institute, Agricultural Research Center, Giza, EgyptHeshamAbo El-SoudSoils, Water and Environment Research Institute, Agricultural Research Center, Giza, EgyptJournal Article20191103Poor water quality mainly exists because of the increasing population and horizontal expansion which are associated with deterioration in sanitation and crop productivity.

The results showed that studied soil chemical, physical properties and its fertility parameters were significantly influenced by the individual treatments and recorded highest values due to the interaction among studied treatments after sugar beet and cotton cultivation. The yield of sugar beet and cotton crops were significantly increased and recorded the highest values at the interaction of highest levels of treatments. Therefore, the irrigation and fertilization management could be considered a proper approach to sustain the soil and water resources in particular under arid and semi-arid regions. Further studies are needed for more and novel approaches in handling the salt-affected soilsThe National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Impact of Fulvic Acid and Nitrification Inhibitor on Wheat Production and NO3-N losses in Clay Soil2412546748910.21608/jenvbs.2019.19806.1074ENMohamed SamiElsakasoil, Water and Environment Research institute- Sakha Agricultural Research StationTamerKhalifasoil, Water and Environment Research institute- Sakha Agricultural Research StationHeshmAboElsoudsoil, Water and Environment Research institute- Sakha Agricultural Research StationJournal Article20191119Two field experiments were conducted at Sakha Agric. Res. Station, Kafr El-Sheikh Governorate, Egypt, during two successive seasons (2017/18 and 2018/19) to study the effect of fulvic acid and nitrification inhibitor on NO3 leaching and wheat yield and chemical constituents. A split plot design with three replicates were used with three fulvic acid applied i. e 0, 4.76 and 9.52 kg ha-1 as main plots as well as nitrogen fertilizers as ammonium sulphate (21% N) (with or without nitrification inhibitor (NI)) at rate of 90, 135 and 180 kg N ha-1, in sub-plots. Nitrification inhibitor 3, 4-dimethylpyrazole phosphate (DMPP) (EC 1.7 dS m-1and pH 4.4) was applied at 8%. Results indicated that the highest mean values of EC, OM and available NPK were obtained from soil in plots resaved 180 kg N ha-1 with DMPP + 9.52 kg fulvic acid ha-1. The highest mean values of plant height (110.34 and 111.42 cm); 1000-grain weight (55.60 and 61.00 g); grain yield (7.62 and 7.95 Mg ha-1); straw yield (13.64 and 14.02 Mg ha-1); N concentration in grain and straw were (2.09 and 0.84 %, respectively); N content of grain (152.97 and 149.56 kg N ha-1); N content of straw (99.51 and 95.58 kg N ha-1) and total N uptake by wheat (252.49 and 245.14 kg N ha-1) were recorded by 180 kg N ha-1 combined with 8% DMPP + 9.52 kg fulvic acid ha-1 in first and second seasons, respectively.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Mobility and Potential Ecological Risk Assessment of Copper and Zinc in Alluvial and Marine Soils in The North Nile Delta, Egypt2552686748510.21608/jenvbs.2019.20947.1078ENHebaElbasiounyBiological and Environmental Sciences Department, Faculty of Home Economic, Al-Azhar University, 31511, Egypt0000-0002-7245-6483FathyElbehiryCentral laboratory for environmental studies, Kafrelsheikh University,33516, Egypt.0000-0002-0296-2647Journal Article20191213COPPER (Cu) and zinc (Zn) are micronutrients needed for organisms, however, they are heavy metals and may become toxic to the organisms when exceeding the allowable limit in the environment. Two soil types of marine and alluvial were sampled in the North Nile Delta, Egypt. Copper (Cu) and zinc (Zn) were analyzed to investigate the availability and to evaluate ecological risk assessment and identify pollution sources. Cu and Zn were extracted from soil samples by DTPA-TEA. The higher content of Cu was recorded in alluvial soil, especially in the surface, while Zn concentrations in both soils didn’t differ with depth. Six indices were used in this study to evaluate the potential ecological risk of Cu and Zn in the examined soils. The results of these indices revealed that affecting Cu and Zn anthropogenically in some profiles of the studied soils. As well, the results of principal component analysis (PCA) showed that Cu and Zn in marine soils mainly originated from anthropogenic source, while this is true in alluvial soil in Zn only. Human and agricultural activities may be the main source of Cu and Zn especially fertilizers and pesticides, which indicates that there may be environmental threating by those metals in the study area in the future.The National Centre for Information and Documentation (NIDOC), the Academy of Scientific Research and TechnologyEnvironment, Biodiversity and Soil Security2536-94153201920190201Potential Impacts of Copper Sulfate and Sodium Silicate Salts of Maize Late Wilt Disease and Synthase of Anti-defense Compounds2692827638110.21608/jenvbs.2020.21138.1079ENGamalFarahatPlant pathology department institute, ARC0000-0003-2252-0165Journal Article20191218Corn seeds coating by copper sulfate and sodium silicate salts exhibited non phytotoxic and led to reduce late wilt disease infection percentage under field nursery conditions during two tested seasons of 2017 and 2018 compared to control treatment. A fertilizer by 5-25 gm. of these salts added with first and second irrigates separately to corn seedlings led to retarding of late wilt disease in the field and caused reduction of infection percentage with the most salts tested cons. Reduction of the disease as salts application resulted in enhancement of yield especially with high cons .Increasing of salts cons led to increase the retarding of late wilt disease and reduction of infection percentage. Generally, Copper sulfate was more effective against late wilt disease than sodium silicate and recorded high retarding of disease and the highest enhancement of the yield in comparison of control and other treatments. Induction of peroxidase and polyphenol oxidase enzymes synthase by salts application may be have role in retarding late wilt disease followed by increasing of chemical compounds of fat, ash and carbohydrates contents while antioxidant and total phenols did not effected .
