IntroductionPreliminary research with natural pumice (18,23) has indicated that it might be a useful and inexpensive substrate in experiments on the mineral nutrition of plants. Appreciable surface activity appears to be associated with the high porosity of pumice. An experiment was undertaken to determine the availability to roots of specific elements held on different lots of pumice each of which had been immersed in a single salt solution. This investigation was designed to trace plant growth during the progressive diminution of an individual nutrient element in the substrate, the entire quantity of which wlas initially supplied in an adsorbed state on the pumice, in the presence of a nutrient solution containing all other essential ions in a soluble form and supplied at a uniform rate.

“…Trials were conducted to improve the fertility of various soils by means of adding natural or synthetic ion exchangers containing one (Greenhill and Page, 1933;Wiklander, 1957) or several (Converse et al, 1943;Arnon and Grossenbacher, 1947;Doubsky et al, 1965;Podlesakova, 1979) nutrient ions. In some cases a positive effect of using such fertilizers was observed.…”

The effect of 2% (v/v) addition of ion exchange substrate to a sandy soil on the growth of Dactylis glomerata L., used as a test species, was studied. Four different exchange additives having pH values in the range 4.45-7.14 were evaluated in pot experiments. These additives were prepared as mixtures of monoionic forms of a strong acid cation exchanger and a weak base anion exchanger, loaded with nutrient ions. The additions of the ion exchange substrates to the sand affected plant growth advantageously, increasing the total dry biomass 3.8-8.5 times. The most efficient additive appeared to be the substrate with the lowest pH because it contained the largest stock of nutrient elements. The excessive acidity of the additive was spontaneously neutralized in the mixtures with sand due to reaction of the acid excess with carbonates present in the natural sandy soil.

“…The use of synthetic ion-exchange resins as a source of adsorbed ions for plant growth was first proposed by Schlenker (1942) and Converse et al, (1943) Their studies showed that in systems in which all nutrient ions were supplied in an adsorbed form, the high selectivity for Ca and Mg required daily additions of K to maintain adequate amounts of t h e s e ions in s o l u t i o n . In s t u d i e s of p l a n t response to nutrient ion concentration, control at realistic levels is imperative.…”

Release characteristics of ion-exchange resins as buffers in low ionic strength nutrient solutions

1993

The use of synthetic ion-exchange resins as buffers of nutrient ions is a potential mechanism for the control of ion concentrations in nutrient solutions. In this study equilibrium constants for two cation exchange resins and three anion exchange resins were determined at 25°C in low ionic strength systems. The measured constants were used to successfully predict the resin combinations required to achieve desired solution equilibrium concentrations. The effectiveness of these resins in buffering solution ion concentrations was evaluated by examining their release characteristics in circulating systems from which aliquots of solution were withdrawn and replaced with deionised water to simulate plant uptake. Buffering of N O 3 and S Q concentrations was effective when manual control of one anion was imposed. The cation resins were ineffective in buffering the concentrations of Ca and Mg with a tendency for the resins to retain most of the Ca and Mg in adsorbed form.

The Use of Ion Exchange Materials in Studies on Corn Nutrition

Abstract: (7), who have studied artificial zeolites and the clay fraction from the soil and used them as a source of ions for plants. ALBRECHT and MCCALLA (1) give a very good account of this subject and references to previous work.
