Abstract

Cations leaching from leaf litter of Melia azedarach (Linn.) was studied in laboratory. About 37% of initial dry weight of leaf litter was lost after 72 hours. Conductivity and total dissolved solid (TDS) of the leached water significantly (p<0.05) increased to 475 µS cm-1 and 227 mg l-1, respectively. pH of the leached water dropped to 5.64 at the end of the experiment. Conductivity and TDS showed significant (p<0.05, r=0.99) positive linear relationships with the weight loss of leaf litter. The concentration of P, K and Na in leaf litter significantly (p<0.05) decreased to 24 mg g-1, 2247 mg g-1 and 900 mg g-1, respectively and PO4, K and Na in leached water significantly (p<0.05) increased to 0.16 ppm, 5.44 ppm and 5.58 ppm, respectively. Nutrients (P, K and Na) in leaf litter showed significant (p<0.05, ranged from -0.92 to -0.99) negative relationship with the weight loss. But, nutrients (PO4, K and Na) in leached water showed significant (p<0.05, ranged from 0.90 to 0.98) positive linear relationship with the leaching time.
