{"title":"EFFECT OF ORGANIC AND SYNTHETIC SOIL CONDITIONERS WITH DIFFERENT NITROGEN LEVELS ON THE PERFORMANCE OF WHEAT IN SANDY SOIL","authors":"H. Z. El-abdeen, Gehan H. Youssef, S. Sayed, Marwa Shady","doi":"10.51193/ijaer.2022.8506","DOIUrl":"https://doi.org/10.51193/ijaer.2022.8506","url":null,"abstract":"The main problems of sandy soil are its inability to hold on to nutrients, its fast drainage, its lack of soil structure and its small buffering capacity. It cannot hold on to nutrients because it has little or no clay and organic matter. Therefore, the objective of this study was to determine the effect of the combined application of some synthetic soil conditioners with two forms of humic acids (HA) as organic soil conditioners in reducing nitrogen fertilizer requirements to maximize wheat yield productivity. So, two experiments were designed in a split-split plot design with three replicates at the Experimental Station Farm in El-Ismailia governorate during the two successive winter seasons using wheat plant (Triticum Sativacv Giza 168). The treatments included two forms of organic acids and synthetic soil conditioners in the presence of three levels of nitrogen fertilizer. The common agricultural practices for growing wheat according to the recommendations of the Ministry of Agriculture were followed. Obtained results revealed that the application of humic acids type either HK or HCa in combination with PVA or bitumen emulsion under different application rates of nitrogen fertilizers enhanced wheat plant productivity (yield, straw, and grains kg/fed) along with uptake macronutrient as compared to control treatment. The superior one was HCa in combination with PVA and B in presence of 75% N application in the first and second season, respectively. Moreover, soil fertility was improved by adding soil conditioners in different forms with/without nitrogen fertilizers as compared to the control treatment i.e. EC values, OM, and available NPK were significantly increased in all treatments applied; the maximum increase was observed with HCa combination with B at 75% from nitrogen dose. Also, the same trend was observed with dry stable aggregates and total porosity of sandy soil for an average of two seasons. An opposite trend was observed with bulk density whose values generally decreased with all treatments. In conclusion, can be clarified that the application of humic materials either HK or HCa was increasing soil fertility which is reflected in wheat plant productivity but it was more efficient when in combination with synthetic polymers especially B, and can save about 25% from nitrogen fertilizer applied.","PeriodicalId":182275,"journal":{"name":"International Journal of Agriculture and Environmental Research","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126413928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In natural antimicrobial research, however, plants, especially herbs and spices, are given more attention; this chapter focuses on new fruit and vegetable discoveries. In addition to bacteriocins, microorganisms which are used in food fermentation often develop various antimicrobial metabolites, including organic acids, hydrogen peroxide, ethanol, and diacetyl. Animal products such as tissue, milk and eggs contain various antimicrobial agents, mostly in the form of peptides (polypeptides). In certain cases, to be tested or added to food products, natural antimicrobials are extracted and purified. Extraction and purification can alter the chemical structure of and influence the functionality of natural antimicrobials. Thus, in order to avoid potential modification or degradation of active ingredients, an extraction method with minimal processing such as juice or mechanical direct extraction seems to be more promising. The behavior of natural antimicrobials may also be affected by the original source, harvest time and growth stage. These natural antimicrobial compounds could be affected by food components, processing, and storage in food applications. Growing consumer fears regarding chemical antimicrobials, on the other hand, and increasing resistance of pathogenic microbes have drawn the scientific community's attention to studies on the possible antimicrobial activity of natural products. Natural antimicrobials are normally recognized as safe and the most promising solution appears to It is for microbial resistance and might better meet the demands of consumers for healthy foods. Recent perspectives on the antimicrobial activities of natural plant products, extraction methods, modes of action and factors affecting antimicrobial activity have been addressed in this review article.","PeriodicalId":182275,"journal":{"name":"International Journal of Agriculture and Environmental Research","volume":"952 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133923813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim of the current work is the investigation of using small wind turbines in greenhouses located in Crete, Greece for electricity generation. Crete hosts the majority of greenhouses in Greece which are mainly used for vegetable production. Use of wind turbines like other distributed electricity generation technologies has many economic and environmental benefits and they are highly desirable. The wind energy potential in various locations in Crete has been estimated as well as the electricity generated by small wind turbines from existing studies. In locations with high average annual wind speeds in Crete the cost of wind electricity is lower than the cost of grid electricity. In some of these locations there is a high concentration of greenhouses. Provided that net-metering regulations allow, additionally to solar electricity, generation of wind electricity use of small wind turbines in greenhouses with high annual electricity demand in Crete is economically profitable and environmentally attractive.
