Soil bacteria boost root lignin, helping crops survive salty farmland
Scientists have discovered that beneficial soil bacteria help plants survive in salty conditions by stimulating the production of lignin, a natural compound that strengthens roots and boosts resilience — rather than by keeping salt out. Greenhouse and field tests confirmed healthier plants and higher yields in salty soils. The findings could lead to bio-based treatments that open up previously unusable farmland to agriculture.
