Popis:	Symbiotic nitrogen fixation is an essential ecological attribute for sustained amelioration of severely eroded, low fertility soils. The long‐lived perennial, Sericea (Lespedeza cuneata (Dument) G. Don.), is highly tolerant of depleted soil conditions and has exceptional nitrogen fixation capabilities. Objectives of this study were to determine nodulation characteristics, with adjunctive governing factors, that influence 20 year‐age Sericea growth, effectual nitrogen fixation and subsequent improved soil productivity of eroded Dougherty loam (Loamy, mixed, thermic, Arenic Haplustalf). A first‐year lime application resulted in significant favorable Sericea growth and nitrogen fixation throughout the 20‐year period. Sericea growth and nodulation declined approximately one‐third during the second decade of plant age. However, annual nodule regeneration remained at nearly the same level. Peak nitrogenase activity levels occurred with favorable mycorrhizal colonization. Distinctive nonmature and matur...
