TUNING CRYSTAL GROWTH OF HYDROXYAPATITE NANOPARTICLES FOR ENHANCED FOLIAR PHOSPHORUS DELIVERY

Le résumé fourni par la source

Phosphorus fertilization remains inefficient in many cropping systems, motivating the search for alternative delivery methods that minimize losses and boost plant uptake. Nano-sized hydroxyapatite particles have become a promising phosphorus source, though their effectiveness heavily relies on particle design. In this study, we synthesized nano-sized hydroxyapatite by hydrothermal method with controlled crystal growth and physicochemical properties to better suit foliar applications. We systematically examined how synthesis parameters affect particle size, morphology, and crystal growth to identify an optimal suspension formulation for foliar fertilization. Foliar application trials of engineered nano-sized hydroxyapatite on potato plants showed successful uptake. These findings indicate that controlling the crystal growth of nano-sized hydroxyapatite could provide a basis for developing advanced nanofertilizers with improved nutrient efficiency.
