Environmental Impact Assessment and Source Identification of Total Suspended Particulate Matter and Some Elements Emitted from a Workplaces in Jordan Authored by Omar Ali Al Khashman The objective of the present study was to assess the extent and severity of atmospheric particulate concentrations and metal concentration in dust, street dust and soil in the Aqaba Industrial Estate (AIE). Samples of dust, street dust and soil were analyzed for their contents of atmospheric particulate matter and elements (Fe, Cu, Ni, Pb, Zn, Mn and Cr) after digestion with nitric acid. This study shows that analyzed major sources and magnitude of elements pollution. The mean concentrations of the elements were as follows: CFe > CPb > CZn > CCr > CMn > CCu and CCd where C stands for concentration. Zn, Cd and Pb were in high levels in the area close to the workplace, while the chromium level was low. This study indicates that all of the elements are concentrated on the surface soil, and dec...

Yam-Based Cropping Systems Performances with Chemical Fertilizers Authored by Raphiou Maliki Yam (Dioscorea spp.) is a tuber crop widely cultivated in the humid and sub-humid lowland regions of West Africa and the Caribbean. More than 90% of the worldwide production (40 million metric tons of fresh tubers year-1) is produced in West Africa [1].   Yam cultivation in West Africa is now confronted with the scarcity of fertile soil available for clearing [2]. In Benin nowadays, farmers hardly have the possibility to rely on long duration fallow and yam is being cultivated in 1 or 2-year herbaceous fallow–yam or maize-yam rotation systems with manual incorporation of residue into the soil.   The decline in yam yields under continuous cultivation has led to the largely accepted conclusion that yam requires a high level of natural soil fertility (organic matter and nutrient) (O’Sulllivan and Ernest, 2008). Since the demand for yam keeps increasing due to the continued population gro...

A Prevalence Study of Ectoparasites on The Long- Eared Hedgehog (Hemiechinus Auritus) in Sohag Governorate, Egypt Authored by Abd El Aleem SS Desoky Hedgehogs are small, nocturnal and spiny-coated mammals which are found in synanthropic environments and they are kept as pets by some people [1,2]. As hedgehogs feed on insects, worms, centipedes, snails, mice, frogs, lizards and snakes, they are considered as useful animals for natural ecosystems and are in the protected species list [1]. They are ideal hosts for ecto and endoparasites, because they have active foraging behavior and do not groom themselves [3]. On the other hand, these animals can serve as reservoir for some zoonotic pathogens. Hedgehogs acquire some pathogens through tick or flea bites and are involved in the endemic cycle of these pathogens. Keeping in mind that Hedgehogs are known as potential host for some variants of Anaplasma phagocytophilum, tick–born encephalitis virus (TBEV), Rickettsia felis, Eucoleus aerophil...

  Tomato Shading Study- Las Vegas 2018 Results Authored by Angela O Callaghan Cooperative Extension in southern Nevada has been recommending shading tomato plants in the summer to extend the season and help improve production as well as quality. The question remained “Does shading up tomatoes really help in such a harsh desert climate, and if so, how much shade? Do all tomato cultivars benefit equally?” This research aimed to obtain information that could be useful to small growers, including household growers, who must confront the in this region. We selected four commonly grown tomato cultivars: Celebrity, Early girl, Heat Wave and Red Cherry (a very small-fruited variety). The treatments were, 0%, 30% and 50% shade. We transplanted seedlings into raised beds with organically amended soils. The land where the raised beds were located where plants had not grown previously. Major problems included wind damage, sunscald, herbivory and root knot nematodes. The project had noticea...

  Tapping Soil Microbiota: Overlooked Underground Players in Agricultural Production Authored by Yuan Wang Soil, the base for agricultural production, is constantly influenced by a variety of physical, chemical, and biological factors. Despite the abundance and diversity, soil microorganisms have been largely overlooked until recent a few years, due to the untapped functions caused by the difficulties in microbe isolation and culture. Soil microbiota, by definition, is the microbial communities that reside in specific soil niches. With the advances of next-generation sequencing technologies, more and more soil microbiomes from different soil environments were dissected genetically and functionally. These studies suggest that manipulation of soil microbiota may be one of the potential solutions for next-generation agriculture.   To read more about this article:  https://irispublishers.com/wjass/fulltext/tapping-soil-microbiota-overlooked-underground-players-in-agricult...
