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

    University essay from SLU/Dept. of Agricultural Biosystems and Techology

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

    Abstract : 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.

  3. 12. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    University essay from SLU/Dept. of Ecology

    Author : Marta Holmlund; [2023]
    Keywords : wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Abstract : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

  4. 13. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    University essay from SLU/Dept. of Ecology

    Author : Yixian Chen; [2023]
    Keywords : density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Abstract : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. READ MORE

  5. 14. Secrets of the Seeds : exploring the relationship between seed morphology and seed quality in Lepidium campestre, a novel oil crop for Northern Sweden

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Keywords : Lepidium campestre; field cress; oil crop; plant breeding; domestication; seed morphology; seed colour; seed analysis; Northern Sweden; glucosinolate;

    Abstract : This study set out to explore relationships between seed morphology and qualitative traits in field cress, Lepidium campestre, with the goal of assisting the breeding process of this crop under domestication. A collection of seeds of L. campestre as well as related species was analysed for weight and size using a MARViN seed analyser. READ MORE

  6. 15. Föryngring med hägn : effekten av viltbete på självföryngrad ädellövskog i tre skånska naturreservat

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Håkan Ramberg; Kaj Sjöqvist; [2023]
    Keywords : Bokskog; naturlig föryngring; betesbegärlighet; viltbete; strukturförändring;

    Abstract : Ädellövskogens artsammansättning styrs av flera naturliga processer, en av dessa processer är viltbete. Bete kan leda till att trädslagsfördelningen förändras och att föryngring blir problematiskt, speciellt i områden med stora viltstammar och för de mer betesbegärliga trädarterna. READ MORE
