Nutrients (N, P and K) dynamics associated with the leaf litter of two agroforestry tree species of Bangladesh

Eucalyptus camaldulensis (Dehnh.) and Swietenia macrophylla (King.) are not native to Bangladesh, but they are widely used in agroforestry practices for their commercial values. Selection of tree species with efficient return of nutrients is a vital challenge in agroforestry practices to maintain the soil fertility for sustainable crop production. Therefore, a comparative study was conducted on nutrients (N, P and K) leaching from leaf litter of E. camaldulensis and S. macrophylla in laboratory condition. The initial dry weight of leaf litter of E. camaldulensis and S. macrophylla were significantly (pN>P) release during the leaching process. Nutrients (N, P and K) concentration in leaf litter of these species showed significant (p
