The full potential of glauconite-based nanocomposites as micronutrient fertilizers remains underexplored, particularly their interaction with Zn, Cu, and B. Despite the promising applications, mechanisms nutrient sorption effects on plant growth require further investigation, especially concerning structural changes delivery efficiency. This study investigates modification glauconite B solutions to create multifunctional enhanced properties. It was established that activation process preserves primary globular–lamellar morphology while introducing changes. Nanocomposites were synthesized using chemical characterized XRD, SEM-EDS, TEM, FTIR, BET analyses. Agrochemical tests evaluated oat under controlled conditions. zinc sulfate exhibited an increase in specific surface area mesoporosity, enhancing capacity facilitating formation inner-sphere complexes mineral’s basal surface. Modification copper led secondary phases, such sulfates, surfaces microflakes globules preserving crystalline structure coordination Cu2+. Boron-modified by localized restructuring, pore channeling, mesopore diameter, along outer-sphere relative glauconite. Thermogravimetric calorimetric analyses mass spectrometry revealed endothermic exothermic effects, Zn-modified samples, confirming dehydration energetics. Agricultural oats (Avena sativa) demonstrated effectiveness Cu- B-modified improving parameters, including a 7% height 6.4% dry weight. showed high germination rates (up 100%) at low dosages but optimization avoid phytotoxicity higher concentrations. findings highlight adapting for targeted release. Additionally, have applications restoring degraded soils, treating polluted runoff, developing slow-release agrochemical systems.
