Soil salinization is one of the most serious problems facing soil fertility, crop productivity and sustainable agricultural development in Egypt. The risk present, when it leads to toxicity. This study focuses on evaluation at East Nile Delta enhance management strategy program using geographical information system (GIS). Two different classifications salt-affected soils, agronomic classification Russian classification, were used. Ninety-two surface samples collected depth 0–30 cm. Inverse...

The issue of soil contamination is one the most important subjects that interests decision-makers all over world. It also related to fertility and food security. soils adjacent drains in Egypt suffer from increasing concentration heavy metals, which negatively affects crop quality. Precise spatial distribution maps metals are an essential key mitigating negative impacts on ecosystem. Sixty random locations El-Moheet drainage were chosen west side Nile River, El-Minia governorate, Egypt. Six...

Potentially toxic elements (PTEs) pose a significant threat to soil and the environment. Therefore, fast quantification of PTEs is crucial for better management contaminated sites. Versatile technique such as Visible near-infrared spectroscopy (Vis–NIRS) (350–2,500 nm) has attracted tremendous attention assessing achieved promising results combined with successful multivariate analysis. This research investigated potential Vis–NIRS partial least squares regression (PLSR) variable selection...

Rapid and unplanned urbanisation can lead to altered local climate by increasing land surface temperature (LST), particularly in summer months. This study investigates the Urban Heat Island (UHI) Greater Cairo, Egypt, using remote sensing techniques estimate LST of months over 45 years (1986, 2000, 2017, predicted year 2030). The research objectives steps were, 1- mapped use/ cover (LULC), 2- conducted spatiotemporal analysis LST, with a comparison change across different types, 3- future...

The biochar application can improve the physiochemical properties of both sandy and clayey loam soils is considered a potential adaptation tool toward climate change. Therefore, current study novel in combining water-hyacinth-derived with organic manures as suggested effective way treating soil under arid semiarid conditions. Water hyacinth weeds were slow pyrolyzed at temperature 300 °C, which resulted nonalkaline pH value 6.31, suitable for alkaline soils. A pot experiment was established...

Newly reclaimed sandy soils under arid conditions are characterized by poor physical and biochemical properties specially, rapid organic matter decomposition. Field experiment was developed to investigate the feasibility of using poultry manure its derived biochar integrated with different levels N fertilizer as a soil amendment for newly in Western Desert El-Minia Governorate, Egypt. Results showed that application (PM) or (PMB) combination inorganic had caused significant changes on range...

This researchconducted to evaluate the relationship between status of total and available Cr,Cd, Ni Pb physiochemical properties different agricultural soils El-Minia Governorate, Egypt. To realize this goal, combined twenty one surface soil samples (30-cm depth) signifying main great groups Governorate were collected tested for in relation toheavy metals soil.Positive negative high significant correlations found contents all studied heavy elements properties.Statistical analyses show that,...

Soil application of water hyacinth biochar as a source nutrient- and carbon-rich biomass may be an effective ploy to eradicate this invasive aquatic weed. Incubation trial was conducted assess effects addition on some sandy soil biochemical biological properties potential carbon sequestration at different rates methods. Results demonstrated that pyrolysis temperature 300 °C 30 min furnace residence time produced with coveted physicochemical properties. Field emission scanning electronic...

Drought stress is a group of abiotic stresses that affects plant growth and yield production. A field experiment over two successive seasons (2021–2022 2022–2023) in sand soil was conducted to investigate the integration effect deficit irrigation, amendment “hundzsoil”, spraying proline on water use efficiency (WUE), yield, fruit quality 8-year-old Crimson seedless table grapes. Four application rates (0, 2, 4, 6 kg hundzsoil /vine) were added during dormancy period, four irrigation levels...

Introduction: Benzene is an important raw material for the manufacture of synthetic rubbers, gums, lubricants, dyes, pharmaceutics and agriculture chemicals. Occupational exposure to may induce some adverse health effects. Aim work: This study aimed evaluation among petrol Stations workers byassessment symptomatic, hematological immunological changes by using trans- trans muconic acid (t, t MA) as a urinary indicator. Subjects Methods: A comparative cross – sectional was conducted on five...

Driven by spreading Jerusalem artichoke (sunchoke) cultivation for increasing food production and to reduce environmental risks of intensive inorganic fertilization, the target this research is evaluate influences using potassium humate as organic fertilizer on soil properties, microbial activities, yield components see if removal immature flowers will affect plant growth.To achieve target, tubers were planted in clay loam during two successive summer seasons 2014 2015 Middle Egypt.Results...

Sandy soils occupied a considerable area of marginal lands in arid and semi-arid regions. Previous studies on biochar paid rare attention its particle size effect soil properties, usually used < 2 mm size. The aim was to focus the impact different sizes some sandy physical biological properties barely growth. This develop management strategy for using as conditioner soil. Laboratory experiments were conducted evaluate possibility two (< 2-5 mm) at application rates, 1% 1.5% (w/w), with an...

Biofertilizers and biocontrol agents have been improved for several decades as microbiological tools that can provide beneficial outcomes in the growth health of plants. Two field experiments were performed Scientific Farm Horticulture Department, Faculty Agriculture, Minia University, Egypt during winter 2022/2023 using clay loam soil. Control plots treated with recommended rates mineral fertilizer NPK (100%) without inoculation, while other inoculated Egyptian isolates effective...

Biochar is projected as a soil conditioner to amend physical and chemical properties.However, behavior of biochar in alkaline soils under arid semi-arid conditions Egypt not much investigated.In this study, field experiments were carried out greenhouse explore the effect applying sugarcane bagasse with two different ways at three rates (10, 20 30 ton ha -1 ) on some properties clay loam tomato growth yield.The conducted for successive seasons 2015 2016.Mixing top surface reduced particle...

The turbidite sands of the Nile Delta Plio-Pleistocene section have been demonstrated to be a good quality reservoir within Egyption Mediterranean Gas Province.Exploration has based in last decades on definition clear direct hydrocarbon indicators (DHI), as bright spots, flat amplitude shut-offs, polarity reversals,….etc.In this paper, seismic attributes technique; such root mean square (RMS) amplitude, reflection intensity, instantaneous frequency and Instantaneous phase are applied 2D...
