  1. 11. Hur odlare genom odlingsåtgärder kan påverka mikrolivet i jorden : en litteraturstudie

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

    Author : Maria Olsson; [2018]
    Keywords : mikroorganismer; mikrober; bakterier; svampar; gynna; nytta; odling; marktäckning; plöjning; organiskt material;

    Abstract : Jordens mikroliv har visat sig vara känsligt för de störningar som människan orsakar vid brukning av jorden. Ett rikt mikroliv är viktigt för jordens funktionalitet och antalet mikroorganismer kan ses som en indikator för jordens hälsa och kvalitet. READ MORE

  3. 12. The effects of changing temperature and precipitation on free-living soil Nematoda in Norway

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Raluca Munteanu; [2017]
    Keywords : soil nematodes; Norway; climate change; temperature; precipitation; Earth and Environmental Sciences;

    Abstract : The life cycle and behavior of free-living soil nematodes is highly dependent on environmental factors such as temperature and soil moisture, fluctuations leading to significantly lower development and activity rates, dormancy and/or mortality. This literature review summarizes present knowledge about free-living soil nematode temperature and moisture requirements, as well as the commonly accepted predictions about climate change-induced temperature and precipitation changes in Norway.

  4. 13. Growth and phosphorus uptake of potato (Solanum tuberosum L.) in an alkaline soil as affected by mineral nitrogen forms and inoculation with phosphate-solubilizing bacteria and mycorrhizal fungi

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

    Author : Kristina Weimers; [2017]
    Keywords : alkaline soil; ammonium chloride; ammonium nitrate; ammonium sulphate; AMF; Bacillus megaterium; Solanum tuberosum L; P deficiency; potassium nitrate; Rhizophagus irregularis;

    Abstract : In soils with relatively high pH (pH > 7), potatoes (Solanum tuberosum L.) and other phosphorus (P) demanding crops might suffer from P deficiency despite P fertilization and significant reserves of P in the soil. Also, a high risk for P deficiency for potatoes may be expected when the soil is cold and the root system undeveloped. READ MORE

  5. 14. Biotiska faktorers inverkan på markstrukturen

    University essay from SLU/Dept. of Soil and Environment

    Author : Sanna Krüger Persson; [2017]
    Keywords : markstruktur; näringsväv; feedback; markorganismer; aggregat;

    Abstract : Soil structure is a key factor in the functioning of soil, including its ability to support root growth. Soil structure influences the circulation of nutrients and affects the gas exchange, and acts as habitat for the soil organisms. READ MORE

  6. 15. Microbial communities in a boreal forest podzol profile and responses to the presence of Pinus sylvestris seedling roots

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Johanna Jernberg; [2013]
    Keywords : Archaea; Bacteria; Boreal forest; DGGE; Fungi;

    Abstract : The boreal biome consists of coniferous forests that cover much of the northern hemisphere, and constitute an important natural resource for the forest industry, but has also gained attention in the light of global warming in acting as potential sinks of atmospheric carbon dioxide. Both forest production and carbon sequestration are closely connected to the activities of soil microorganisms, which play major roles in nutrient cycling and decomposition of plant biomass. READ MORE
