Abstract

Zeolites are a group of minerals, with a special structure giving them properties like ion-exchange capacity and the ability to act as molecular sieves. Due to these properties zeolites have a wide range of applications in various areas.
ZeoPro is a commercial product, based on natural zeolite minerals and developed as a plant growth medium. It is claimed to improve plant performance, utilize nutrients more efficient and reduce nutrient leaching to the environment. In this study the effect of ZeoPro on cucumber and tomato seedlings was evaluated when 5%, 10% and 20% ZeoPro was mixed into the growth medium. The results showed some increase in growth when ZeoPro was added to the growth medium. In cucumber the growth increased with increasing amount of ZeoPro, generating the largest plants with 20% ZeoPro and the smallest in the control group without ZeoPro. In tomato, the largest plants were found in the 5% group closely followed by the 10% and 20% groups. The plants in the control group, grown without addition of ZeoPro were clearly smaller than the other groups.

Zeoliter är en grupp mineraler med speciell struktur vilken ger dem egenskaper som jonbytarkapacitet och möjlighet till molekylsiktning. På grund av dessa egenskaper har zeoliter ett stort antal skilda användningsområden.
ZeoPro är ett planteringsmedia baserad på naturliga zeoliter. Det sägs ge kraftfullare plantutveckling, högeffektivt näringsutnyttjade och reducera näringsläckage till omgivningen. I den här studien utvärderas effekten av ZeoPro på småplantor av gurka och tomat, när 5%, 10% och 20% ZeoPro blandades i växtsubstratet. Resultaten visade på en viss ökad tillväxt vid tillsats av ZeoPro. På gurka ökade tillväxten med ökat innehåll av ZeoPro och gav störst plantor vid 20% innehåll av ZeoPro och minst plantor i kontrollgruppen utan tillsats av ZeoPro. I tomat fanns de största plantorna i 5%-gruppen tätt följda av 10%- och 20%-grupperna. Plantorna i kontrollgruppen, utan tillsats av ZeoPro, var tydligt mindre än de andra grupperna.
