Summary
1. Taking over from the Agency of Agricultural Property of the State Treasury or purchasing
from private owners the strips of land at least 10 m wide which are adjacent to the
waters of the river Oder catchment area. In the areas where arable lands lay directly next to
the river, where mineral and organic fertilizers, as well as pesticides, are intensively used, it
is proposed to plant trees and shrubs on the 10 m wide strips adjoining the river, and to plant
such species as reed and reed-mace in the direct vicinity of the river.
2. The construction of ditches, parallel to the river, and ended with reservoirs planted
with underwater and submerged vegetation absorbing large quantities of nutrients. The
ditches are proposed to be built along the stretches of the Oder and its tributaries most
heavily threatened by non- point pollution.
3. The wide use of soil analyses carried out for the nutrient requirements contained in
fertilizers used there, which will permit the optimal use of these fertilizers. Additionally,
several small applications of fertilizer should be administered in proper times, instead of
one big one. One solution is to promote organic farming methods in the Oder valley.
4. The enhancement of the autopurification capacity of the Oder and its tributaries
through the development of rich plant communities and associations in the river and along
its banks:
• diversifying the cross-section of the river bed,
• extension of the river length,
• planting of reed, reed-mace, and other submerged vegetation along the banks,
• planting of underwater vegetation in the river current,
• increase of aeration of the river waters through the construction of swift currents,
steps, and deeps,
• facilitating the flooding of parts of the valley and the filtration of the inundation
waters through the soils.
5. Increasing pressure on the Czech Republic to make it undertaking decisive steps
towards reducing the pollutants discharged in the waters of the Oder on Czech territory.
6. Initiating cooperation with nature conservation and environmental protection authorities
in Germany, especially with the local authorities of the regions neighbouring with the
Oder, in order to undertake joint activities related to the protection of the river and its valley.
7. Undertaking all possible activities aimed at resolving the problem of the discharges to
the Oder of saline mining waters from the coal mines in the Czech Republic and Poland.
8. Supporting the project of injection of saline water from the Legnica G³ogów Copper
Mining Complex into the deep excavations created following the extraction of natural gas.
9. Intensifying projects aimed at constructing and modernizing old waste water treatment
plants, especially where their operation can bring the most significant results. It is particularly
important to ensure that phosphorus and nitrogen substances are removed. Those activities
are most important in the nine key areas of the Oder catchment basin, which are the
sources of the largest burdens of pollutants. They are: Ostrava (The Czech Republic), the
