Synthesis of zeolite-based nanofertilizers: approach and characteristics

Abstract

Background and Aim. The rising cost of mineral fertilizers negatively impacts the competitiveness of agricultural production, necessitating innovative technologies. One promising solution is the use of zeolite-based nanofertilizers, which provide gradual and prolonged nutrient release. This study aimed 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, environmentdependent nutrient release. Biological tests indicated enhanced plant growth and increased resistance to abiotic stress.

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