The main physiographic units and its soil taxonomic ; family levels could be classified as follows: 1-    Soils of Playa: a-     Typic Haplosalids, fine loamy over sandy skeletal, mixed, hyperthermic. b-    Duric Haplosalids, sandy skeletal, mixed, hyperthermic. 2-Soils of Sabkha: Lithic Gypsisalids, sandy skeletal, siliceous, hyperthermic, shallow. 3- Soils of Sand Sheets: Calcic Haplosalids, sandy skeletal, mixed, hyperthermic, deep. 4- Soils of Peniplain: Typic Haplosalids, clayey skeletal, hyperthermic. 5- Soils of Cultivated plain: a- Typic Torriorthents, fine loamy, mixed, hyperthermic. b-Typic Torriorthents, clayey over fine loamy skeletal, mixed, hyperthermic. c-Typic Haplosalids, coarse loamy skeletal over clayey, mixed, hyperthermic . d-Typic Haplosalids, fine loamy over coarse loamy, mixed, hyperthermic.   The statistical size distribution reveal that these soils have mainly  poorly sorted sediments with near symmetrical to fine skewed materials and lepto kurtic to meso kurtic pattern. These parameters indicate that the studied area is formed under water or both water and wind action, forming of non- uniform parent materials.   Current suitability of the studied soils could be categorized into three suitable classes; moderately suitable (S2) , marginally suitable (S3) and not suitable (N1) with different intensity degree of soil limitations. By existing suitable improvement practices, the potential suitability classes assessed are two suitability classes; moderately suitable (S2) and not suitable (N2).   Data revealed that current suitability for some specific crops were not suitable (N), except for some scattered areas developed on cultivated plain which are suitable for all the studied crops. On the other hand, the potential suitability classes differed according to the satisfaction conditions between different properties of soils developed on the studied physiographic units and crop water requirements. However, soils of sabkha and cultivated plain are highly suitable (S1) for groundnut. Also, soils of peniplain and cultivated plain are highly suitable (S1) for potato and grapes. Whereas, soils of playa, peniplain and cultivated plain are moderately suitable (S2) for olives.   Water of wells and springs are considered the main sources for irrigation in El- Dakhla Oases soils. Data revealed that the suitability of irrigation water had (C1–S1) class with non restriction at west El–Mowhob and Kalamon area , while it represented (C4–S4) class with very high salinity levels and very high alkalinity hazard at El- Zaiate well and Bathor spring waters, indicating severe restrictions in these soils.   Data revealed that the crop water requirement values of some specific crops are considered high, due to the highness of evapotranspiration values. It represented with an average of 500, 800 and 1800 mm/s for vegetable, field and fruit crops, respectively. So, it is very important to apply suitable irrigation systems such as trickle or sprinkler, under these conditions.                                         }, keywords = {Keywords: GIS,Land evaluation,Soil Taxonomy,and Crop water requirements}, url = {https://ejss.journals.ekb.eg/article_1572.html}, eprint = {https://ejss.journals.ekb.eg/article_1572_7a7b0ff41b21d4a0e522c8179ee62fe8.pdf} } @article { author = {}, title = {Heavy Metals Immobilization in Sewage Sludge Using Some Amendments}, journal = {Egyptian Journal of Soil Science}, volume = {56}, number = {1}, pages = {31-40}, year = {2016}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2016.1593}, abstract = {}, keywords = {Silica gel,Cement Bypass,Rock phosphate and charcoal activated carbon,Stabilization,Sewage Sludge}, url = {https://ejss.journals.ekb.eg/article_1593.html}, eprint = {https://ejss.journals.ekb.eg/article_1593_737b2c43c05ed29d55876016451463ca.pdf} } @article { author = {}, title = {Phosphorus Fertigation and Preplant Conventional Soil Application of Drip Irrigated Grapevines}, journal = {Egyptian Journal of Soil Science}, volume = {56}, number = {1}, pages = {41-51}, year = {2016}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2016.1594}, abstract = {}, keywords = {grapevine,phosphorus,fertigation,Preplant application}, url = {https://ejss.journals.ekb.eg/article_1594.html}, eprint = {https://ejss.journals.ekb.eg/article_1594_3fcd9b450be9115158e038de9aff43b0.pdf} } @article { author = {}, title = {The Integration Effect between Mineral and Bio￾fertilization on Wheat Production in Soils High in Iron at the New Valley, Egypt .}, journal = {Egyptian Journal of Soil Science}, volume = {56}, number = {1}, pages = {53-68}, year = {2016}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2016.1595}, abstract = {}, keywords = {New Valley soils,P,Zn,mycorrhizae,Azotobacter,Iron content,Wheat}, url = {https://ejss.journals.ekb.eg/article_1595.html}, eprint = {https://ejss.journals.ekb.eg/article_1595_75f148e0907ea3b52b778e9fc7d52cda.pdf} } @article { author = {}, title = {Effect of Mineral Fertilization and Some Organic Compounds on Faba Bean Crop in some Soils at the New Valley, Egypt}, journal = {Egyptian Journal of Soil Science}, volume = {56}, number = {1}, pages = {69-91}, year = {2016}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2016.2344}, abstract = {    FIELD experiments were carried out during two successive years in two sites at the New Valley, Egypt. The first site was clay soil located at El-KaserVillage, El-Dakhlla Oasis and the second site was sandy soil located at El-Monera village, El-Kharaga Oasis. Seeds of faba bean variety Rebaya were cultivated in both the two studied locations. This study was designed in order to improve the yield of faba bean under conditions of the NewValley soils by the combination of mineral fertilizers and some organic compounds. Nitrogen (N), phosphorus (P) and potassium (K) fertilizers were applied as soil and foliar applications at different rates. Different rates of boron (B), molybdenum (Mo) and zinc (Zn) were applied as foliar applications. Some organic compounds viz., humic acid (HA), amino acid (AA), ascorbic acid (AS) and licorice extract (LC) were combined with mineral fertilizers.   Application of N, P and K along or with B, Mo and Zn increased yield and nutrient contents of faba bean. The treatments of mineral fertilizers and organic compounds further increased yield components, nutrient contents, total antioxidants activity and total phenol of faba bean in both soils. Organic compounds increased the yield and their effectiveness could be arranged as: LC < HA < AA< AS in ascending order.  Mixing these compounds had higher effect on yield and nutrient contents than individual applications. Their effect could be arranged in ascending order as: LC + HA< LC + HA + AA< AS + AA + HA< AS + AA + HA + LC. The AS had the highest effect on total phenols and antioxidants. The LC had higher values than HA and AA treatments, respectively. The most effective treatment in the yield was (AS + AA + HA + LC + N2P2K2 + with micronutrient), which achieved 5.95 and 2.73 t fed-1 of shoot and seed, respectively in sandy soil. In clayey soil, these values were 8.91 and 4.30 t fed-1, respectively. Regarding total antioxidants and phenols, the same treatment could achieve the highest values in both soils recording 216 and 227 μg ascorbic acid ml-1 extract and 791 and 876 μmol of gallic acid ml-1 extract for shoot and seed, respectively in sandy soil. These values were 231 and 243 μg ascorbic acid ml-1 and 891 and 983 μmol of gallic acid ml-1 in clayey soil, respectively. This study demonstrated that incorporating some organic compounds along with mineral fertilizers has a beneficial effect on yield and quality of faba bean.    }, keywords = {Mineral fertilizers,Organic compound,yield,Faba bean,Sandy and clay soils in NewValley}, url = {https://ejss.journals.ekb.eg/article_2344.html}, eprint = {https://ejss.journals.ekb.eg/article_2344_7a2022fcf47424b3a50d168c5333e891.pdf} } @article { author = {}, title = {Influence of Foliar Applied Mineral and Bio￾fertilizers on the Yield Parameters of Fig and Olive Trees Grown in the Northwestern Coast of Egypt}, journal = {Egyptian Journal of Soil Science}, volume = {56}, number = {1}, pages = {93-112}, year = {2016}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2016.1596}, abstract = {}, keywords = {Integration of foliar mineral and bio-fertilizers,Fig and olive fruits,Valleys in the North-Western Coast,Matrouh Governorate,Egypt}, url = {https://ejss.journals.ekb.eg/article_1596.html}, eprint = {https://ejss.journals.ekb.eg/article_1596_c118b6cfb50019c4bad49c73cef8fe33.pdf} } @article { author = {}, title = {Some Soil Properties, Growth Parameters and Crop Yield as Responded to Soil Temperature Management}, journal = {Egyptian Journal of Soil Science}, volume = {56}, number = {1}, pages = {113-130}, year = {2016}, publisher = {The National Information and Documentation Centre (NIDOC) affiliated to Academy of Scientific Research and Technology(ASRT)}, issn = {0302-6701}, eissn = {2357-0369}, doi = {10.21608/ejss.2016.1597}, abstract = {}, keywords = {soil hydraulic properties,Soil temperature fluctuation,Maize,Faba bean}, url = {https://ejss.journals.ekb.eg/article_1597.html}, eprint = {https://ejss.journals.ekb.eg/article_1597_511152d3b1ef78c859a04098982db9da.pdf} } @article { author = {}, title = {Evaluation of Bio-and Mineral Phosphorus Fertilizers Accompanied with Foliar Application of Micronutrients on Quantity and Quality of Soybean (Glycin max L.)

The results showed that the yield and its components were significantly increased with the levels of mineral P-fertilizers, biological P-fertilizers and foliar spray of micronutrients alone or in combination. Also, the results disclosed that the highest values of yield components obtained with a combination of P rate of 22.5 kg P2O5/fed with inoculation of P-biofertilizer and foliar spray of micronutrients. Application of phosphorus at the rate of 22.5 kg P2O5/fed in combination with phosphorus dissolving bacteria significantly increased the uptake of macro-, micro-nutrients, protein and oil contents. Moreover, the combined application of mineral phosphorus and foliar micronutrients application had a positive effect on N, K, Mn, as well as protein and oil content. The interaction between phosphorus level at 22.5 kg P2O5/fed, phosphorus biofertilizer and foliar micronutrients had a significant influence on uptake of K, Fe, and Mn in seeds of soybean plants.
