Diversity of arbuscular mycorrhizal fungi and its chemical drivers across dryland habitats
( Springer , 2021 , Article)Qatar is largely characterized by a hyper-arid climate and low soil fertility which create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. In a study of AM fungal communities and their relationship with ... -
Dolomite: Perspectives on a perplexing mineral
( research qate , 2009 , Other)Dolomite is a metastable mineral that can precipitate directly from solutions containing magnesium, calcium and carbonate to form cement or unlithified sediment. It can be categorized into two classes such as penecontemporaneous ... -
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
( Trans Tech Publications , 2010 , Conference Paper)Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism ... -
The effect of type and combination of fertilizers on eukaryotic microbiome of date palm rhizosphere
( Springer Nature , 2024 , Article)The date palm (Phoenix dactylifera) is an important cultivated crop in arid areas. Here, we studied the effect of plant genotype and type of fertilizers on the eukaryotic community structures of the date palm rhizosphere. ... -
Effect of Water Stress (Drought and Waterlogging) on Medicinal Plants
( Springer Nature , 2023 , Book chapter)Climate change causes different biotic and abiotic stresses to the plants, water stress being one of them. Water stress includes water-logging (flooding) and water deficit (drought). These stresses restrict the plant’s ... -
Effects of ambient climate and three warming treatments on fruit production in an alpine, subarctic meadow community
( Wiley , 2021 , Article)Premise Climate change is having major impacts on alpine and arctic regions, and inter‐annual variations in temperature are likely to increase. How increased climate variability will impact plant reproduction is ... -
Effects of Climate and Atmospheric Nitrogen Deposition on Early to Mid-Term Stage Litter Decomposition Across Biomes
( Frontiers Media , 2021 , Article)Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity and quality as well as microbial community abundance ... -
Effects of Coupling Water and Fertilizer on Agronomic Traits, Sugar Content and Yield of Sugarcane in Guangxi, China
( MDPI , 2022 , Article)This work is a contribution to applied water and fertilizer coupling efforts aiming at increasing crop productivity on sugarcane plantations through the analysis of average cane yields obtained following main agronomic ... -
