  1. 1. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Ellen Ek Moreau; [2023]
    Keywords : Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Abstract : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

    Author : Gabriel Thor; [2022]
    Keywords : markpackning; hållfasthet; markstruktur; marktextur; direktsådd; reducerad jordbearbetning;

    Abstract : Att gårdar blir större är en tydlig trend inom det svenska lantbruket. Med det följer även en större efterfrågan på större maskiner och redskap. Denna rationalisering medför en ökad risk för att åkermarken blir kraftigt packad och därigenom skadad, vilket på sikt kan leda till försämrad bördighet. READ MORE

  6. 5. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden
