Fosforläckage från hästhagar i Hågadalen : Åtgärdsförslag till den småskaliga hästhållaren

Sammanfattning: The title of this degree project is “Phosphorous losses from horse paddocks in Hågadalen – action proposals for the small scaled horse keeper” Phosphorus losses from human activity is a global problem that requires identification of sources and action proposals. The purpose of this work is to identify the need for action in and near the horse paddocks in Hågadalen, and to find possible measures that the horse keepers can use. Reports from various state authorities, other degree projects and current research reports is the basis of the literature study in this report. Existing calculations of pasture acreage in Hågadalen have also been used. The calculations shows that despite that the pasture is a small percentage of the total acreage the losses from the paddocks is a significant part of the total losses. By modifying some of the horses feeding from oats to hey, the phosphorus losses could be reduced. Possibly could feeding areas also be governed by the same regulations as storage of manure. Rules about cleaning paddocks which houses more than three horses per hectare could also be considered.
