Abstract

Background and Objectives: Nutrient cycles in forests are tightly linked to the hydrological cycle because water acts as the main solvent and transporting agent for nutrient from the aboveground tree canopy to the underlying soil. The aim of this research was to evaluate the monthly and annual changes in chemical properties (calcium, sodium and potassium) of the canopy and Litter leaching of hornbeam (Carpinus betulus L. ) trees during a year compared to nutrients in rainfall (RF). Materials and Methods: This study occurred from January 2012 to February 2013 in a mixed natural stand at Shastkalate Forest Research Station of Gorgan University of Agricultural Sciences and Natural Resources. In a 5000 m2 area in the study site 3 healthy trees with free and symmetrical crown and stem were selected for sampling of RF, throughfall (TF) and litterfall (LF) chemistry. RF, TF and LF were sampled after each rainfall within a year. The collectors were emptied after each rainfall (as soon as rain ceased) and were thoroughly rinsed with deionized water and dried before being replaced. To analyze the chemical content of RF, TF and LF, samples were transported to the laboratory of Gorgan University of Agricultural Sciences and Natural Resources and stored at 4 º C. The concentrations of sodium (Na+), potassium (K+) and calcium (Ca2+) were determined using flame photometer. In order to compare amount of nutrients in TF and LF with RF and to investigate monthly nutrient dynamics of TF and LF, t-test analysis and the one way variance analysis were used. Results: Results showed that Na+ amount in TF (116. 37 kg ha-1year-1), and K+ and Na+ amounts in LF (158. 45 and 78. 79 kg ha-1year-1 respectively), were significantly lower than K+ and Na+ (217. 72 and 172. 82 kg ha-1year-1) in RF (P<0. 05). Also amounts of nutrient leaching of TF and LF in various months were different significantly. The highest leaching amounts of Na+, K+ and Ca2+ were observed for TF, 24. 51, 58. 30 and 3. 14 kg. ha-1, respectively. However highest amounts of Na+ and Ca2+ were measured in October for LF; 19. 93 and 4. 17 kg. ha-1, respectively. Also the lowest leaching of Na+, K+ and Ca2+ of TF (0. 84, 3. 22 and 0. 15 kg ha-1 respectively) and LF (0. 45, 0. 52 and 0. 03 kg ha-1 respectively) were measured in September. Conclusion: In this complex process, in crown cation exchange, the absorption tendency of hornbeam crown was higher than its cation diffusion from leaf and branch tissues, so hornbeam crown tends to absorb nutrition from RF to meet its nutrient need.
