    Sammanfattning : The last decades have shown increased nitrogen leeching from soil to water recipients. This is in Sweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and the declining extent of wetlands. LÄS MER

  7. 5. Näringsläckage från åkermark inom Brååns dräneringsområde : lokalisering och åtgärdsförslag

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Berit Arheimer; [1991]
    Nyckelord :nutrient leakage; arable land; soil water; erosion; localization; control program; natural nutrient traps; agricultural measures; Earth and Environmental Sciences;

    Sammanfattning : The river of Bråån is heavely polluted by nutrient leakage from arable land. The aim of this study is to propose measures designed to reduce nutrient transport within the dranaige basin (165 km2). Leaking areas of the arable land were located and measures were suggested where they would be most effective. LÄS MER
