  2. 6. Crop diversification across scales : implications for resource use and cropping systems sustainability

    Author : Carolina Rodriguez Gonzalez; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The industrialization of agriculture and efforts to maximize yields of commodity crops are major drivers of biodiversity loss and disruption of ecosystems balance. To become more sustainable, agriculture needs to be aligned with the delivery of multiple ecosystem services, and reduce its dependency on external inputs and its negative environmental impacts.

  4. 7. Friend or Foe? Biocontrol interactions of Pythium oligandrum within the potato cropping system

    Author : Christian Benjamin Andersen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The potato crop is a valuable but vulnerable food source on a global level. It is under constant pressure from destructive plant diseases such as early and late blight. Traditionally to control these diseases farmers have relied heavily on synthetic fungicide use. READ MORE

  5. 8. Diversified agroecosystems for biodiversity and ecosystem services : Ecological intensification of faba bean cropping under land use and climate change

    Author : Chloë Raderschall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Loss of natural habitats and lack of continuous floral resources in intensive agricultural landscapes limit the population growth of ecosystem service providers, such as pollinators. Weakened ecosystem service delivery and climate change stressors contribute to crop yield instability. READ MORE

  6. 9. Diversifying crop rotations for sustainable production and climate change adaptation

    Author : Alessio Costa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Industrial cropping systems are increasingly simplified, with fewer crops being grown, requiring extensive use of inputs, and contributing to environmental pollution and climate change. Solutions are needed to reduce the negative effects, while retaining productivity in the face of increasingly frequent detrimental climatic conditions. READ MORE

  7. 10. Recycling Filter Substrates used for Phosphorus Removal from Wastewater as Soil Amendments

    Author : Victor Cucarella Cabañas; Gunno Renman; Greg Morrison; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Compact filter; Filtra P; Phosphorus recycling; Polonite; Soil amendment; Sorption isotherms; Soil science; Markvetenskap; Solution chemistry; Lösningskemi; Agricultural engineering; Jordbruksteknik; Water engineering; Vattenteknik; Environmental chemistry; Miljökemi;

    Abstract : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. READ MORE
