Effect of Decomposition of Leaf Litter on Available Nitrogen and Sulphur in Simarouba Glauca and Calophyllum Inophyllum Agro Forestry Tree Species
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
Field experiment, “effect on decomposition of leaf litter, available nitrogen and sulphur of simarouba glauca and calophyllum inophyllum agro-forestry tree species” was conducted at GKVK, Bengaluru and ARS Hassan during winter and summer 2014-15. The experiment comprising of sixteen treatments consisting of two tree species, two depths, two locations in two seasons, laid out in factorial RCBD with three replications. The leaf litter production quantified for two seasons during winter and summer (November to April 2015) in Simarouba and Calophyllum at two locations revealed that the highest leaf litter fall was recorded during winter in Simarouba (24.33 kg tree-1 month-1) and lowest in Calophyllum (2.7 kg tree-1 month-1) during summer. The available soil nutrients were significantly higher at 90 days after leaf litter decomposition in Simarouba plantation (N-193.8 kg ha-1, and S-29.7 ppm) compared to Calophyllum plantation (N-174.5 kg ha-1, and S-24 ppm), respectively. The Simarouba tree species litter had a higher initial nutrient content and released its nutrients faster with higher proportion than the Calophyllum tree, thus significantly higher soil fertility was obtained in Simarouba agro-forestry system.
