6. Diversity of soil microbial communities: In the perspective of targeting functional genes
Sammanfattning : 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. LÄS MER
7. Imprint of management on microbial communities in arable soil : implications for N2O emissions
Sammanfattning : Arable soils are a major source of the greenhouse gas nitrous oxide (N2O), emissions of which are directly linked to increased use of N fertilizers. Microbial communities that drive N cycle processes in soil ultimately determine the fate of reactive N inputs and control N2O emissions. LÄS MER
8. Tillage practices and their impact on soil organic carbon and the microbial community
Sammanfattning : Soil microorganisms are important for climate regulation as well as for plant nutrition. In agricultural soils the microorganisms are affected by management choices, like which type of tillage that is used. LÄS MER
9. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants
Sammanfattning : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. LÄS MER
10. The influence of soil pH on plant and microbial communities in sandy grasslands
Sammanfattning : 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. LÄS MER
