    Author : Lesya Pronoza; [2017]
    Keywords : Phytoremediation; sustainable development; marginalised regions; cadmium; Nicaragua;

    Abstract : Soil pollution is one of the problems that obstruct sustainable development in the affected regions, posing a threat to the local environment, ecosystems and human wellbeing. Phytoremediation is one of the techniques used to clean polluted soils. READ MORE

  3. 17. Minimized nutrient leaching through fertilizer management : an evaluation of fertilization strategies

    University essay from SLU/Dept. of Soil and Environment

    Author : Joachim Nachmansohn; [2016]
    Keywords : fertilization; fertigation; environment; demand-driven; Ingestad; nutrition; soil;

    Abstract : Nutrient leaching causing surface- and groundwater pollution and eutrophication is one of the main environmental problems of modern society. Plant production is among the quantitatively most important sources of nutrient leaching, particularly of nitrogen and phosphorus, which stands in focus in remediating these problems. READ MORE

  4. 18. Effect of planting density and abiotic conditions on yield of Betula pendula and Pinus sylvestris seedlings in monoculture and mixture

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

    Author : Jennifer McGuinness; [2014]
    Keywords : abiotic environment; Betula pendula; density gradient; Interaction effects; Pinus sylvestris; Planting density; planting composition; seedling yield;

    Abstract : How the yield of mature stands changes in response to factors such as stand composition, planting density and abiotic conditions is a developing topic, and underpins models and generalizations used by forest managers today. However, these generalizations are both the subject of debate and are limited to mature stands, leaving a knowledge gap concerning both mixed species stands and younger stands. READ MORE

  5. 19. Grödans kontra odlingssystemets effekt på frilevande nematoder

    Abstract : Nematodes are perhaps the most common animals in the world. Nematode populations can reach densities up to several millions per square meter in the soil. There are many factors which affect nematode communities in arable soil with respect to diversity and population size. READ MORE

  6. 20. Nutrient effects on microorganism communities in nutrient poor soils

    University essay from SLU/Dept. of Soil and Environment

    Author : Kajsa Söderström; [2012]
    Keywords : soil microorganism activity; MicroResp; fertilizers; nutrients;

    Abstract : Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. READ MORE
