Overview

Controlled experiment reveals that native bacteria and bone-derived nanofertilizers boost phosphorus uptake in early maize, highlighting a soil-dependent role for recycled fertilizers.

Key Points

To determine whether climate-adapted native phosphate-solubilizing bacterial consortia enhance early maize growth, phosphorus nutrition, and uptake when applied alone or combined with salmon-bone nanohydroxyapatites across diverse soils.
Screened 59 native bacterial isolates from Mediterranean, Continental, and Arid agroecosystems for traits including phosphate solubilization, indole-3-acetic acid production, and biological nitrogen fixation.
Inoculated maize seeds with site-specific bacterial consortia and evaluated growth under controlled conditions in matching soils with and without salmon-bone nanohydroxyapatite fertilization.
Screened bacterial strains exhibited nanohydroxyapatite phosphate-solubilization efficiencies between 4.8% and 11.4%, achieving maximum soluble phosphorus release of 34.5 mg L⁻¹.
Bacterial inoculation increased substrate bacterial biomass across all test environments by 47% in Mediterranean, 56% in Continental, and 155% in Arid soils.
Maize biomass gains occurred primarily in Continental and Arid soils, with Arid soils uniquely displaying upregulation of root phosphate transporter genes (ZmPHT1;1, ZmPHT1;2, and ZmPHT1;6) and enhanced phosphorus recovery efficiency.
