Abstract:
The aim of the study was to develop filters in order to decrease the nutrient and solid-matter load to waterways. It is difficult to prevent completely the transfer of solids and nutrients to lower water systems with traditional water protection methods (e.g. sedimentation tanks) used in forestry. Filter tests were carried out in order to find a solution, which would complement and enhance the existing methods. During the improvement of ditches, it was observed that the filter solutions retained a relatively small amount of nutrients. Various filter materials retained some nutrients, but the amounts were minimal. The observed changes were so small, that they are assumed to remain within the margin of error. In general, the amount of nutrients (nitrogen, phosphorus) in forestry water systems is so minimal that retaining them using mechanical methods is quite difficult.
