    Sammanfattning : As of 2020 an estimated number of 821 million people across the world are undernourished and that figure is expected to grow by 2 billion before the end of 2050 (United Nations Sustainable Development 2020). Despite this, every year over 1/3 of food produced globally is disposed of without consumption (Global Panel on Agriculture and Food Systems for Nutrition 2018), and the actual number might be much higher.

  4. 3. Potential uptake of phosphorus by catch crops in greenhouse conditions and release after freezing-thawing

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Rafa Abdulhassan Khalaf; [2013]
    Nyckelord :catch crops; freezing-thawing; phosphorus uptake-release; root morphology;

    Sammanfattning : Catch crops are an important component of cropping systems in Sweden and other Scandinavian countries, but may contribute to phosphorus (P) losses after freezingthawing cycles (FTCs). Eight existing and new catch crop species in Swedish farming were grown in a greenhouse to study potential P uptake and P release from shoots, roots and whole plants after FTCs. LÄS MER
