: Soil carbon sequestration is a riskier long-term strategy for climate mitigation than direct emissions reduction as it plays a main role in closing carbon emission gaps. Mangrove ecosystem is a natural wetland that allocated at Red Sea and extended for 500 km at the Egyptian western coast. Five sampling sites were investigated at the north near to the city of Hurghada beginning from the Abu Monquar Island (27° 12′ 58′′N, 33° 52′ 34′′E). This work investigates the impact of the original population of Mangrove type (Avicennia marina ) on the soil carbon sequestration. Obtained results of the mean values of measured soil bulk density (SBD) at the soil surface (0-30 cm) were revealed that the lowest values of the SBD was at Abu Monquar Island with 1.31± 0.02, g cm -3 and at Safaga with 1.53 ± 0.05 g cm -3 . While at El Gouna 1, 2 and at Hurghada the SBD values varied from 1.63 to 1.75 g cm -3 . In addition, the soil dry bulk density at the control site (beach without plants) was 1.75± 0.05g cm -3 . On the other hand, the highest values of the Calcium carbonate were obtained Abu Monquar island with 168. 20 gKg -1 , while the Calcium carbonate values were 26.60 gKg -1 , 69.30 gKg -1 , 58.50 gKg -1 , 91.90 gKg -1 and 26.90 gKg -1 for Gouna1, Gouna2, Hurghada, Safaga, and the control, respectively. The mean values of measured soil organic carbon pool (SOCP) at the soil surface (0-90cm) revealed that the lowest values of the SOCP was at Hurghada with 8.81± 0.12 Mgha -1 and the highest values at Abu Monquar island with 59.75 ± 0.15 Mgha -1 . While at El Gouna 1, 2 and at Safaga the SOCP values were 14.48, 12.86, and 39.98 Mgha -1 , respectively. In addition, the SOCP at the control site (beach without plants) was 6.62± 0.25 Mgha -1 . Thus the Mangrove ecosystem has a great potential to sequestrate the soil organic carbon and reduce the atmospheric CO 2 .
与直接减排相比，土壤固碳是一种风险更大的减缓气候变化的长期战略，因为它在缩小碳排放差距方面发挥着主要作用。红树林生态系统是分布在红海沿岸，在埃及西海岸延伸500公里的天然湿地。从Abu Monquar岛(北纬27°12′58”，东经33°52′34”)开始，在赫尔格达市北部附近调查了5个采样点。本研究探讨了红树林类型(Avicennia marina)原始种群对土壤固碳的影响。得到的土壤表面(0 ~ 30 cm)实测土壤容重平均值显示，阿布蒙夸尔岛(Abu Monquar Island)和萨法加(Safaga)土壤容重最小，分别为1.31±0.02 g cm -3和1.53±0.05 g cm -3。而在El Gouna 1、2和Hurghada, SBD值从1.63到1.75 g cm -3不等。对照场地(无植物滩涂)土壤干容重为1.75±0.05g cm -3。另一方面，以Abu Monquar岛的碳酸钙含量最高，为168。Gouna1、Gouna2、赫尔格达、萨法加和对照的碳酸钙含量分别为26.60 gKg -1、69.30 gKg -1、58.50 gKg -1、91.90 gKg -1和26.90 gKg -1。土壤表层(0 ~ 90cm)实测土壤有机碳库(SOCP)均值显示，赫尔格达岛最低，为8.81±0.12 Mgha -1，阿布蒙夸尔岛最高，为59.75±0.15 Mgha -1。而El Gouna 1、2和Safaga的SOCP值分别为14.48、12.86和39.98 Mgha -1。对照点(无植物海滩)的SOCP为6.62±0.25 Mgha -1。因此，红树林生态系统在固存土壤有机碳和减少大气co2方面具有很大的潜力。

: This investigation was carried out at the experimental farm, Faculty of Agriculture, Zagazig University through the growing summer season of 2019. This study was conducted to evaluate the effect of inorganic, organic and bio-fertilization on plant growth and NPK content by successive four cuts of sudan grass plants grown in clayey soils. The most important findings could be summarized as follows: Generally, in most cases, adding any organic sources i.e., chicken manure (CM) or rabbit manure (RM) or Quail manure (QM) or farmyard manure (FYM) at the rate of 0.5% with50 % RD (NPK) plus inoculated by microbien (Mic.) gave the highest significant values of four cuts and accumulative fresh weight as well as N, P and K percentage of sudan grass grown in clay soil compared with control treatment. As a general view, the fresh weight and N percentage of sudan grass grown in clay soil was increased from 1 st cut to 2 nd one then decreased in 3 rd cut followed by last one using the control treatment or 100% RD (NPK) with or without microbien inoculated or 50% RD (NPK) with CM, QM, RM and FYM with microbien inoculated. The same trend was noticed for P% using the microbien inoculated with 50 % RD (NPK) or 50% RD (NPK) alone or control treatment. Also, the fresh weight of sudan grass was increased from 1st cut to 2nd one followed by 3rd cut then decreased in last one by adding the treatment of 50% RD (NPK) with QM or CM. Similar trend was obtained for N% by adding the 100% RD (NPK) with or without microbien inoculated or 50% RD (NPK) with Mic. The same trend was noticed for P% by adding 50% RD (NPK) plus 0.5% of any organic wastes with or without microbien inoculated. Similar trend was obtained for K% by adding 50% RD (NPK) plus 0.5% of any organic wastes with microbien inoculated compared with control treatment. In general, it could be stated that to increase forage production and its quality of sudan grass, mineral with organic and bio-fertilizer can be used at rate of 50% NPK mineral fertilizers with any organic wastes plus bio- fertilizer (microbien)under the same soil conditions.

: The main goal of the present research is to investigate the possibility of recycling agricultural residues for producing different types of pressed wood. All experimental work was conducted using a mixture of wood saw dust + linen sass + corn stalks with equal percentages, to produce samples of different types of pressed wood. The main experiments were carried out to control and study the effect of some different operating parameters (pressing pressure (1, 3, 5, 7 MPa), pressing time (5, 10, 15, 20 min.) and resin type (Urea formaldehydes and Speria formaldehyde) affecting the pressed wood production processes. The produced pressed wood was evaluated taking into consideration physical properties (Density, thickness swelling and water absorption), mechanical properties (Modulus of elasticity, modulus of rupture, and internal bond strength) and final product quality. The obtained data reveal that the produced pressed wood quality were meeting the required physical and mechanical properties as stated in the standard quality guidelines under conditions of 5 MPa pressing pressure and 15 min.. pressing time with the use of urea formaldehyde resin. The findings also illustrated that by controlling both pressing pressure and pressing time, a mixture of wood saw dust + linen sass + corn stalks with equal percentages could be used to produce different types of pressed wood (Particleboards, PB; Medium density fiberboards, MDF and High density fiberboards, HDF).

: The impact of replacement monosodium glutamate (MSG) with a ratio of 1:1 mixture of salt and sugar on the microbiological quality of deep fat fried chicken breast strips throughout frozen storage (-18°C) for 90 days was assessed. Also, the antibacterial activity of monosodium glutamate and a mixture of salt (sodium chloride) and sugar can (sucrose) in a ratio of 1:1 was determined by disc diffusion assay, the minimum bactericidal concentration (MBC) and the minimum inhibitory concentration (MIC). Results showed that Gram-negative bacteria since the mean values of the inhibition zones were in the ranges of 11.8, 13.4, 15.4, and 16 mm when studying the effect of monosodium glutamate on Escherichia coli , Serratia marcescens , Bacillus cereus, and Staphylococcus aureus , respectively. Also, the mean values of the inhibition zones were in the ranges of 14.2, 15.6, 18.2, and 17 mm when studying the effect of the mix of sugar and salt in a ratio of 1:1 on Escherichia coli , Bacillus cereus, Serratia marcescens , and Staphylococcus aureus , respectively. The average MIC and MBC values of monosodium glutamate against Gram-negative bacteria were 37.5 and 75 µg/ml, respectively, while these values were 32.5 and 65 µg/ml against Gram-positive bacteria, respectively. Also, the average MIC and MBC values of the mix of sugar and salt in a ratio of 1:1 against Gram-negative bacteria were 27.2 and 55 µg/ml, respectively. While these values were 22.5 and 45 µg/ml, respectively against Gram-positive bacteria, respectively. Besides, the results demonstrated that the control of chicken strips possessed the uppermost values of total bacterial count and the least values of total coliform count compared to the remaining treatments. Salmonella and Escherichia coli were not found in both treatments up until the ending of the storage period. The control of chicken strips possessed the least counts of total Staphylococcus aureus , total psychrophilic bacteria, and yeast and mold counts compared to the remaining treatments.
