Abstract
A method is evaluated that employs variation in stable C and N isotopes from fractionations in C and N acquisition and growth to predict root biomasses of three plant species in mixtures. Celtis laevigata Willd. (C3), Prosopis glandulosa Torr. (C3, legume) and Schizachyrium scoparium (Michx.) Nash (C4), or Gossypium hirsutum L. (C3), Glycine max (L.) Merr. (C3 legume), and Sorghum bicolor (L.) Moench (C4) were grown together in separate, three-species combinations.
