1. Soil salinity as a driver of microbial community structure and functioning
Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

3. Effects of heavy metal contamination on carbon and nitrogen cycling : An ecological approach to assess risks to soil functions
Abstract : Soil contamination with heavy metals may disrupt soil microorganisms with important roles in carbon (C) and nitrogen (N) cycling. However, there is a lack of understanding on how microorganisms are affected in soil, which may lead to a mismatch when assessing risks of contaminants to field soils. READ MORE

4. Diversity of soil microbial communities: In the perspective of targeting functional genes
Abstract : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. READ MORE

5. The influence of soil pH on plant and microbial communities in sandy grasslands
Abstract : Sandy, calcareous grasslands are species rich temperate semi-natural grasslands. The species composition in 136 plots was analysed in relation to soil chemistry parameters; extractable P and N, soil pH and lime content. READ MORE
