Soil surface electrochemical properties, such as specific area and charge number, are important indexes to evaluate the agricultural soil quality change. However, there is not enough focus on effect of different improved materials reclaimed characteristics. Therefore, we selected maturing agent (TM), fly ash (TF), organic fertilizer (TO), + (TMO), (TFO), no modified material (CK) treatment for ...

It has long been considered that ferric phases stabilize organic matter (OM) in soils. Temporarily waterlogged soils, which Fe is submitted to regular reductive solubilization and oxidizing precipitation, have often used study these processes. However, few studies interested the evolution of OM quality under such conditions. We therefore experimentally investigated impact a redox cycle on disso...

Coastal sediments are considered to be final receptacles for organic and inorganic contaminants. Characterizing those assessing their biodegradation potential have become a great challenge in recent years. In this study, the chemical composition, including content polycyclic aromatic hydrocarbons, microbial community abundance diversity (using culture-independent approaches targeting 16S rRNA g...

Winter jujube (Ziziphus jujuba Mill. cv. Dongzao) is highly popular due to its attractive taste and flavor of fruits. However, cultivation facing a serious obstacle for the substantial decrease in fruit soluble solids contents. In this study, four commonly-used fertilization types, including organic manure application (OM), combined NPK fertilizer (OC), at high rate (HC) low (LC) were selected ...

The study of individual difference variables in the realm of written feedback is one of the significant lines of research which has been reinvigorated in the last few years. These variables are believed to affect both students’ engagement with feedback and their writing improvement. The present correlational study investi- gated the relationship betw...

One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...
