  2. 6. Earthworm and arbuscular mycorrhizal communities in agricultural soils : management of key soil organisms for sustainable agriculture

    Author : Kaisa Torppa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Intensive agriculture is detrimental to soil biodiversity and functioning. Promoting communities of key soil organisms, such as earthworms and arbuscular mycorrhizal (AM) fungi, may help improve agricultural sustainability by replacing inputs with ecosystem services. READ MORE

  4. 7. Resource efficient control of Elymus repens

    Author : Björn Ringselle; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Elymus repens is a perennial grass weed that causes great yield losses in a variety of crops in the southern and northern temperate zones. Primary control methods for E. repens are herbicides or intensive tillage, both of which have a number of negative side-effects, e.g. READ MORE

  5. 8. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa

    Author : Elin Enfors; Line Gordon; Christian Valentin; Stockholms universitet; []
    Keywords : smallholder farming; water system innovations; agricultural droughts; multi-functional landscapes; development trajectories; uncertainty; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Abstract : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. READ MORE

  6. 9. Diversity of soil microbial communities: In the perspective of targeting functional genes

    Author : Lokeshwaran Manoharan; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soil; metagenomics; sequence capture; microbial communities; functional diversity; taxonomic diversity;

    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

  7. 10. Genome editing of oilseed species by CRISPR/Cas9 for trait improvement

    Author : Sjur Sandgrind; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The demand for vegetable oils for food and other applications is rapidly increasing due to a growing population and an urgent need to replace fossil oils. Furthermore, there are several challenges facing agricultural production, such as a shortage of arable land, climate change, and water pollution due to nutrient leaching from extensive use of fertilizers and tillage.
