Nanoengineered polyglutamic acid fertilizers via self-assembly for efficient tomato growth.

ABSTRACT:

Introduction

Polyglutamic acid (γ-PGA) is a promising biostimulant for enhancing crop growth and stress resistance, while its agricultural application is limited by poor leaf retention, low mobility within plants, and susceptibility to rain wash-off.

Methods

This study developed PGA nanofertilizers via a facile one-step self-assembly strategy in crude γ-PGA aqueous solution without adding salt ions to overcome these limitations. SEM images show that the obtained nanoparticles appear uniform spherical morphology and good dispersibility in water with an average hydrodynamic diameter of 182 nm confirmed by DLS. XRD and DSC patterns indicate a strong reduction in crystallinity consistent with a largely amorphous or highly disordered state.
