Abstract
A hydroponic study was carried out to determine the absorption capacity of some plants in the presence of ion exchange membranes with nutrient solution. Two rice Species Giza 176 and Sakha 101 and two millet species Pearl millet and Berayard millet were used as test plants for the absorption of nutrient elements either from nutrient solution alone, in the presence of cation membrane M-Cation-40, or in the presence of anion membrane M-Anion-40. The obtained results revealed that the absorption from the nutrient solution without any resins was significantly better than that with them. This was referred to that the nutrient solution alone provided the plants with more balanced nutrients than the other ones. It was also observed that cation resins increased the absorption of cations on the account of anions, while the opposite was true for anion resins. The existence of exchange complexes in the root zone significantly affects the absorption of nutrient elements by the roots. It is advisable to apply well-decomposed organic materials to proliferate easy exchange of nutrients for plants, ie. a good mediator between plants, sod and sources of mineral fertilizers. It is also recommended to apply nutrients in a balance With other nutrients as far as possible. The objective of this study was to assess the absorption capacity of the roots of some plants as influenced by the presence of cation and anion resins in the nutrient medium.
