The Impact of Salinity on Root Nodule Development in Plants
Salinity quietly undermines legume productivity long before visible leaf symptoms appear. Root nodules—tiny biological factories that fix atmospheric nitrogen—are among the first tissues to falter when salt concentration climbs. Salt ions shrink nodule number, cut nitrogenase activity, and shorten nodule lifespan. The result is a hidden hunger that no fertilizer top-dressing can correct. How Salt…
