Abstract
The first use of synthetic ion exchange resins in agricultural research goes back to 1942 [1] and 1943 [2] when ion exchange resin was used as a source of adsorbed ions for plant growth in sand culture systems. Although further studies of using ion exchanger as a source to provide nutrient ions in a medium for plant growth and as a means of buffering nutrient solution have been reported [3 - 11], the majority of ion exchange resin studies have focused on their use in exchanging initial counter-ions for other ions (e.g. nutrient ions) in the soil, thereby acting as a nutrient ion sink.
