  1. 1. 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

    Keywords : agroecology; transdisciplinary research; action research; participative video making; eco-efficiency; cosmology; emic perception; indigenous farmers; small-scale farmer; non adoption of innovations; Ratanakiri; Cambodia;

    Abstract : In 2008 the most extensive evaluation of global agriculture in human history notable named “agriculture at a crossroad” was published, indicating that agroecological small-scale farming systems could be a path to follow in the future in order to secure a sustainable food supply. Yet it is claimed that there is a gap between knowledge regarding the methods used for agroecological farming and its application by farmers. READ MORE

  3. 3. Skördeeffekter av biokolstillsats och kompletterande gödsling i två fältförsök

    University essay from SLU/Dept. of Soil and Environment

    Author : Elin Laxmar; [2017]
    Keywords : terra preta; biokol; pyrolys; skörd; kväve;

    Abstract : Biokol är ett material med hög kolhalt som framställs genom en reaktion som kallas pyrolys. Pyrolys är en upphettning av biologiskt material under förhållandevis låga temperaturer och begränsad tillgång till syre. Biokolet som bildas innehåller en hög andel kol och har en stor specifik yta.

  4. 4. Impact of Crop Diversity, Fertilization and Legumes on Soil Organic Carbon in Grasslands

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Kristina Witzgall; [2016]
    Keywords : Soil organic carbon; soil quality; agricultural productivity; perennial production grassland; fertilization; crop diversity; soil carbon; Earth and Environmental Sciences;

    Abstract : Agricultural soil quality is decreasing as a result of the expansion and intensification of agriculture. A key indicator of soil quality is soil organic carbon (SOC) which is degraded when land is converted from natural to cultivated systems and subject to intensive agricultural land use, reflecting reduced soil fertility and productivity.

  5. 5. Tree cover and tree traits affects soil carbon and soil compaction in parklands in central Burkina Faso

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

    Author : Gustaf Dal; [2016]
    Keywords : Burkina Faso; soil; soil organic carbon; dry bulk density; parklands; trees; agroforestry; vegetation density; tree density;

    Abstract : Burkina Faso is a country with an insufficient agricultural production and this is partly due to the fact that the population is growing and also because of environmental factors such as drought, erosion and poor soils. The most common agricultural system in this part of the world is the parkland which can be defined as farmlands with scattered well-grown trees. READ MORE
