  1. 16. The effect of spent mushroom (Agaricus bisporus) compost on the indigenous rhizosphere microbiota in strawberry cultivation

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

    Author : Hani Elaamer; [2020]
    Keywords : Trichoderma spp; Actinomyces spp; Pseudomonas spp; Bacillus spp;

    Abstract : Spent mushroom compost (SMC) is a by-product of mushroom cultivation with the potential to be used in the cultivation system to suppress plant pathogens, enhance water holding capacity, increase soil water aeration and to improve the soil structure through the input of organic matter and additional nutrients. The electric conductivity (EC) as well as pH recorded high values in the SMC, which is a challenge for its application in food production systems. READ MORE

  3. 17. Re-sourcing soil fertility : assessing the soil amendment potential of farm household resources and wastes in Bolo Silasie, Ethiopia

    University essay from SLU/Dept. of Soil and Environment

    Author : Jorunn Hellman; [2020]
    Keywords : nutrient recovery; manure management; ecological sanitation; material flow analysis; East African agriculture;

    Abstract : The global agriculture of today is to a high degree dependent on mineral fertilisers that through a constant accumulation of nitrogen (N) and phosphorus (P) in the biosphere contribute to greenhouse gas emissions and eutrophication of water bodies. At the same time, agricultural productivity around the world is largely constrained by low inputs of plant nutrients. READ MORE

  4. 18. Small-scale biogas production from organic waste and application in mid-income countries – a case study of a Lebanese community

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sebastian Huber; [2019]
    Keywords : Sustainable Development; Lebanon; small-scale; biogas production; organic waste; liquid digestate; anaerobic digestion; feasibility study;

    Abstract : The controlled anaerobic digestion of organic waste in a biogas facility aggregates advantages of waste treatment, energy recovery and nutrient recycling and is a promising technology to deal with contemporary issues of waste management and energy recovery. Small-scale biogas production units can be simply designed and successfully operated even in settings where means for advanced technology equipment are low and institutional capacities limited.

  5. 19. How is feed-related behaviour in growing pigs affected by total mixed ration feed with intensively treated silage?

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Sara Holmström; [2019]
    Keywords : pig behaviour; grass-clover silage; total mixed ration; social interactions; nutrient utilization;

    Abstract : In Nordic countries, roughage e.g. silage from ley crops is mainly provided in the daily feed rations to pigs within organic production systems. Grass-clover silage brings multiple advantages in letting pigs perform natural behaviours and reduces aggressive social interactions. READ MORE

  6. 20. Antinutritionella faktorer i baljväxter : hälsoeffekter, halter och effekter av beredning

    University essay from SLU/Department of Molecular Sciences

    Author : Ylva Henriksson; [2017]
    Keywords : baljväxter; antinutritionella faktorer; proteasinhibitorer; α-amylasinhibitorer; lektiner; saponiner; α-galaktosider; fytat; tanniner; oxalat; lektiner; sojaböna; lupin; bondböna; trädgårdsböna; ärta; lins; beredning; tillagning;

    Abstract : Konsumtion av baljväxter som livsmedel har positiva hälsoeffekter men begränsas av förekomsten av antinutritionella faktorer (ANF). ANF minskar utnyttjandet av näringsämnen genom olika mekanismer, till exempel inhibering av digestionsen-zymer eller komplexbindning med mikro- och makronutrienter, och kan vara direkt skadliga i stora mängder.
