Ethyl cellulose-alginate/poly(vinyl alcohol) dual-layer coating incorporating biochar-immobilized PGPR for controlled urea release, water retention, and plant stress resilience.

Coated controlled-release fertilizers can synchronize nutrient supply with crop demand, yet single-layer systems are often limited by poor structural integrity and restricted functionality. Here, salt-tolerant plant growth-promoting rhizobacteria (PGPR) were immobilized on biochar and embedded in a dually crosslinked p...
