  1. 1. The potential use of black soldier fly larvae residue as a fertilizer

    Master-uppsats, SLU/Dept. of Agricultural Biosystems and Techology

    Författare :An-Marthe Ingelaere; [2023]
    Nyckelord :organic waste; fertilizer; black soldier fly; residue; physico-chemical characteristics; sub-Saharan Africa; socio-economic constraints;

    Sammanfattning : In sub-Saharan Africa (SSA), the primary constraint of agriculture productivity has consistently been ascribed to soil fertility. A common approach to improve soil fertility is the use of fertilizers, both organic and inorganic. Though recently interest is increasing in the use of newer alternatives like biostimulants. LÄS MER

    Sammanfattning : Mawira Sitima is a thermal spring located in the village Sitima outside of Liwonde,Malawi. The spring is used by many of the local villagers to take baths, play around and wash clothes. LÄS MER

  5. 4. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Sara Schützer; [2022]
    Nyckelord :;

    Sammanfattning : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). LÄS MER

  7. 5. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Homayoon Davam; [2022]
    Nyckelord :Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Sammanfattning : High nutrient content of chicken litter has made it one of the best organic fertilizers for agricultural land. However, reusing poultry litter in agriculture can be associated with food-borne pathogens such as E.coli, Salmonella and Campylobacter. LÄS MER
