Beschreibung
Zusammenfassung:	The invention relates to a process for the preparation of water which is suitable for irrigation purposes and for making solutions and dispersions of plant food and crop protection products. The invention provides a simple process for continuously preparing large amounts of softened water without environmentally hazardous by-products and only a moderate consumption of chemicals. Natural water is passed through cation-exchanger resin in ammonium and/or potassium form. The cation-exchanger resin is then regenerated with a solution containing ammonium and/or potassium ions, preferably with a solution of a commercial fertilizer containing such ions.
