    Sieving An Overview Sciencedirect Topics

    Sieving an overview ScienceDirect Topics.Wet sieving was potentially the most adapted method to study microbial community diversity and abundance in soil aggregates in comparison to dry sieving, although it is time consuming and difficult to perform. Furthermore, studies are needed to assess if wet sieving is the relevant method across a larger number of land use and soil types, and ...

    Effects Of Sieving Drying And Rewetting Upon Soil

    Effects of sieving drying and rewetting upon soil.Soil microcosm studies often require some form of soil homogenisation, such as sieving, to provide a representative sample. Frequently, soils are also homogenised following drying and are then rewetted, yet little research has been done to understand how these methods impact upon microbial communities.
