  1. 1. Biochar and hemp as peat substitutes in organic growing media : effects on nutrient availability and nutrient uptake

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

    Author : Malin Nilsson; [2022]
    Keywords : Growing media; substrate; biochar; hemp; peat substitution; nutrient availability; nutrient use efficiency;

    Abstract : This study aimed at evaluating the suitability of biochar and hemp as partial or complete replacement of peat in horticultural growing media, with specific emphasis on the effects on nutrient availability and plant nutrient uptake. The study was motivated by the environmental concerns surrounding the use of peat, along with a desire to explore possible uses for biochar and a crop residue from hemp cultivation. READ MORE

  3. 2. Biochar and Hemp as Peat Substituents in Horticultural Substrates and Their Effects on Presence of Microbiota

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

    Author : Louise Hagbard; [2022]
    Keywords : biochar; hemp; Cannabis sativa; peat reduction; peat; microbiome; fibers; substrate; growing media; Trichoderma; Pseudomonas; Lactuca sativa;

    Abstract : The extraction of peat has been shown to have a detrimental impact on the environment in several ways, including through emissions of greenhouse gases but also through a negative impact on fragile habitats, ecosystems, and ecosystem services. The horticultural sector is a major user of peat products and thus contributes to both emissions and habitat changes. READ MORE

  4. 3. Allelopatisk förmåga hos Cannabis sativa L. (Hampa) och dess potential som biologisk bekämpning av ogräs

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

    Author : Rasmus Lundell; [2022]
    Keywords : Cannabis sativa; allelopati; biologisk kontroll; fytoremediering; ogräs; sekundärmetaboliter;

    Abstract : Sedan människan började kultivera växter har ogräsbekämpning varit en viktig del av odlingen. Under det senaste halvseklet har användningen av kemiska bekämpningsmedel blivit allt vanligare men i takt med att vi sett risker har lagstiftarna tvingats reglera användningen samtidigt som odlare söker alternativ.

  5. 4. Framställning av högkvalitativa textilfibrer av industrihampa (Cannabis sativa L.) under nordiska förhållanden

    University essay from SLU/Dept. of People and Society

    Author : Helena Edén; [2020]
    Keywords : naturfiber; bastfiber; enzymatisk rötning; cottonisering; textilåtervinning;

    Abstract : Textilproduktionens största belastningsområden på miljön är kemikalieanvändning, vattenförbrukning och utsläpp från transporter, och efterfrågan på mer närproducerade material, såsom hampa, ökar. Producenter som vill utnyttja hampans olika delar, däribland fibrer, möter ofta hinder relaterade till att processindustri och kvalitetsspecifikationer saknas. READ MORE

  6. 5. Utilization of Hempseed Press Cake: Optimization of Protein Isolation and Ice Cream Formulation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Erica Forsén; [2020]
    Keywords : Food engineering; Livsmedelsteknik; Technology and Engineering;

    Abstract : Hempseeds, a by-product from hemp fiber production, have a very good nutritional profile, both for essential fatty acids and amino acids, increasing the interest to use hempseeds as a food source. The aims of this project were to optimize the extraction of proteins from hempseed press cake, characterize the functions of the proteins and determine if an ice cream formulation can be created.
