  1. 11. Influence of cropping and fertilization on soil pore characteristics in a long-term field study

    University essay from SLU/Dept. of Soil and Environment

    Author : David Nimblad Svensson; [2020]
    Keywords : X-ray CT; soil structure; biopores; connectivity;

    Abstract : Soil porosity, pore size distribution and pore characteristics such as connectivity are important for a range of soil processes including ease of root growth and air and water transport. The pore structure is therefore an important part of soil fertility. READ MORE

  3. 12. 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. 13. Investigating discouraging and encouraging emic reasons to apply eco-efficient farming methods : a participatory study with indigenous small-scale farmers in Ratanakiri, Cambodia

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

    Author : Lilian-Marleen Beck; [2018]
    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

  5. 14. 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.

  6. 15. 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.
