Implication

Review demonstrates microbial biodegradation strategies for clearing herbicide residues in agricultural soil, highlighting cost-effective consortia for restoring soil ecological health.

Key Points

  • Synthesize current evidence on microbial biodegradation pathways and cost-effective microbial consortia for neutralizing herbicide contamination and restoring degraded agricultural soils.
  • Reviewed degradation pathways including hydrolysis, oxidation, dehalogenation, phosphonate cleavage, and aromatic ring breakdown across bacteria, fungi, and indigenous communities.
  • Evaluated remediation strategies—such as biostimulation, bioaugmentation, compost-assisted treatment, biopiling, slurry bioreactors, and rhizosphere-assisted remediation—targeting atrazine, 2,4-D, and glyphosate.
  • Microbial consortia and locally adapted indigenous strains utilizing low-cost organic amendments provide substantial cost advantages by partitioning complex degradation steps among specialized community members.
  • Field-scale implementation remains constrained by low chemical bioavailability of aged residues, variable soil environments, toxic metabolite accumulation, and poor persistence of inoculated strains.
  • Remediation success requires evaluating broader ecological recovery—such as microbial activity, nutrient cycling, and soil structure—alongside chemical residue degradation.
