1972 Vienna (A) 7th World Fertilizer Congress
The congress was based on a separate concern of the different fertilizer problems in the highly developed and in the developing countries. Corresponding with this subdivision, the subject of this congress was titled “Fertilization in the face of abundance and dearth”. The meeting was attended by more than 300 participants from 29 countries.
It is remarkable that in the discussions one of the viewpoints was concentrated intensively on water pollution and eutrophication problems caused by an inadequate application of fertilizers and/or overfertilization.
