Синтез наноудобрений на цеолитовой основе: подход и характеристики

Abstract

Background and Aim. The rising cost of mineral fertilizers negatively impacts the competitiveness of agricultural production, calling for the introduction of innovative technologies. One promising solution involves the use of zeolite-based nanofertilizers, which ensure gradual and prolonged nutrient release. The aim of this study is to develop nanofertilizers using natural zeolite as a carrier for macro- and micronutrients.

Materials and methods. Natural clinoptilolite from Kazakhstan was modified with phosphorus, potassium, and trace element compounds (Zn, Cu, Mn). The zeolite samples were characterized using FTIR spectroscopy, BET surface area analysis, and atomic absorption spectroscopy.

Results. The modified zeolites demonstrated high nutrient sorption capacity and stable, environment-dependent release dynamics. Biological tests showed enhanced plant growth and increased resistance to abiotic stress conditions.

Conclusion. The synthesized nanofertilizer formulations are ecologically safe, long-lasting, and effective for sustainable agriculture applications.
