Plant health and performance are highly dependent on the root microbiome. The impact of agricultural management soil microbiome has been studied extensively. However, a comprehensive understanding how types fertilization regimes affect both is still lacking, such as microbiome’s stability, whether it follows same patterns In this study, we carried out long-term experiment to see different types...
The objective of this study was to assess the effect of N fertilization in the nursery on frost and water stress resistance of seedlings in Mediterranean forest species. We reviewed the data of six independent fertilization experiments that were performed between 1997 and 2003 in six Mediterranean forest species: three oaks (Quercus suber L., Q. ilex L., and Q. coccifera L.), and three conifer ...
A scoping review was conducted to map the research evidence on the use of videoconferencing for remote health care provision for older adults in care homes. The review aimed to identify the nature and extent of the existing evidence base. Databases used were Embase, Medline, Web of Science, and Cochrane Library Reviews. The review identified 26 articles for inclusion, of which 14 were case stud...
BACKGROUND Obstetrics remains the largest medico-legal liability in healthcare. Neither an increasing awareness of patient safety nor a long tradition of reporting obstetric outcomes have reduced either rates of medical error or obstetric litigation. International debate continues about the best approaches to measuring and improving patient safety. In this study, we set out to assess the feasib...
Nematode communities were monitored for three years in a citrus soil ecosystem in Central Florida under various agricultural regimes comparing standard vs. reduced-input practices. Differences in agricultural regimes consisted of two fertilization levels, two irrigation levels, and two types of ground cover under the tree (herbicide vs. mulch). While some nematodes were affected sporadically by...
In biodiversity experiments based on seeded experimental communities, species richness and species composition exert a strong influence on canopy structure and can lead to an improved use of aboveground resources. In this study, we want to explore whether these findings are applicable to agriculturally managed permanent grassland. Vertical layered profiles of biomass, leaf area (LA) and light i...
In response to increased popularity and greater demand for medicinal plants, a number of conservation groups are recommending that wild medicinal plants be brought into cultivation systems. We collected four medicinal herbs Cichorium pumilum, Eryngium creticum, Pistacia palaestina and Teucrium polium used in traditional Arab medicine for greenhouse cultivation to assess the effects of different...
Improving soil fertility/productivity and reducing environmental impact of nitrogen (N) fertilization are essential for sustainable agriculture. Quantifying the contribution of various fertilization regimes to soil N storage and loss has been lacking in a wide range of spatiotemporal scales. Based on data collected from field experiments at three typical agricultural zones in China, soil N dyna...
Mathematical and experimental simulations predict that external fertilization is unsuccessful in habitats characterized by high water motion. A key assumption of such predictions is that gametes are released in hydrodynamic regimes that quickly dilute gametes. We used fucoid seaweeds to examine whether marine organisms in intertidal and subtidal habitats might achieve high levels of fertilizati...
Fertilization affects bacterial communities and element biogeochemical cycling in flooded paddy soils and the effect might differ among soil types. In this study, five paddy soils from Southern China were subjected to urea addition to explore impacts of fertilization on nitrogen oxide (N2O) emission and bacterial community composition under the flooding condition. 16S rRNA gene-based illumina s...
