A crop growing in the right quantity and quality can only be secured if nutrients are provided in an adequate quantity and available form. Copper (Cu) has primary importance among microelements in growing winter wheat. Lack of Cu hinders nitrogen uptake by plants. Therefore, increasing bioavailability is important in crop production. It has been conducted successful foliar fertilisation experiments with Tetraamminecopper(II) sulphate for several years. The efficiency of the applied compound was enhanced by the application of a retarded nutrient-supply. To secure retardation, ion exchange was carried out in NaA type synthesized zeolite with Tetraamminecopper(II) sulphate. Structure of Tetraamminecopper(II) sulphate, and zeolite ion-exchanged by copper-tetraamine was analysed with a derivatograph and X-ray diffraction. Derivatograph analyses revealed heat stability. X-ray diffraction analyses revealed that copper-tetramine ions exchanged a significant part of the sodium ions of zeolite in ion exchange.
