  1. 1. Optimizing nitrogen fertilization in ley : Evaluating the usage of N-sensor and other tools for optimized nitrogen fertilization

    University essay from SLU/Dept. of Soil and Environment

    Author : Johan Johnsson; [2023]
    Keywords : nitrogen efficiency; optimized fertilization; SN value; unfertilized area; Yara N-sensor;

    Abstract : Nitrogen is an essential nutrient for plant growth. It has several functions in the plant and a lack of nitrogen can cause severe yield losses. READ MORE

  3. 2. Biochar from separated digestate and pig manure as soil amendment

    University essay from SLU/Dept. of Soil and Environment

    Author : Lovisa Nissen; [2022]
    Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

    Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

  4. 3. Modeling self-heating and dry matter loss in large-scale biomass storage

    University essay from KTH/Kemiteknik

    Author : Johan Qviström; [2022]
    Keywords : Modell; biomass; storage; self-heating; dry matter loss; Modell; biomassa; förvaring; uppvärmning; torrsubstansförlust;

    Abstract : Materialförluster och självuppvärmning är ett vanligt problem vid lagring av biomassa i stor skala. Biomassan som lagras bryts med tiden ned av mikroorganismer och kemiska processer vilket resulterar i en förlust av torrsubstans, ofta kring 1-4% per månad. READ MORE

  5. 4. Silage quality of grass and red clover-dominated forages as affected by particle size and additive, when ensiled at different dry-matter concentrations

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Malin Hamberg; [2021]
    Keywords : additive content; dry matter; particle size; silage quality;

    Abstract : Syftet med denna studie var att undersöka effekterna av partikelstorlek samt typ och dosering av kemiska tillsatser på ensilagekvalitet och lagringsstabilitet hos klöverdominerat ensilage och gräsensilage vid två torrsubstans (TS)-halter. Partikelstorlekarna var ca 24 cm för långt ensilage och ca 5 cm för hackat ensilage. READ MORE

  6. 5. Water quality and organic matter linkages in waters draining arable fields

    University essay from SLU/Dept. of Soil and Environment

    Author : Adam Eriksson; [2021]
    Keywords : Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

    Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE
