Application of ion exchange substrates Biona for fertilization of depleted soils and bare sand

The effect of minor additions of ion exchange substrates Biona and mechanical mixtures of ion exchangers, saturated with a full set of biogenic elements, on the productivity of sand and garden soil was investigated. The addition of 2% of substrate Biona increased the crops by four to five times for soil and four to eight times for sand. The effect of the addition of the mixture of the monoionic forms was also very pronounced (two to three times) while less than that of the addition of the ion exchange substrate. Results of the experiments showed that ion exchanger substrates could be used for fertilization of depleted soils.
