Abstract

This work is aligned with the main purpose of REDD+ reward but it needs sufficient records of carbon to develop the Monitoring Reporting and Verification (MRV) system and reference emission level. Hence, the objectives of the study are to compare the carbon stocks of different aged public plantations with respect to neighboring sites, to see the variation in mean annual increment carbon (MAIC) and to assess the variation in amount of nitrogen (N), phosphorous (P) and potassium (K) in soil. Three public plantations in Mahottari district, Tarai were selected for study. Then, random sampling was applied to collect the data from control and plantation sites. Altogether 28 sample plots were distributed on the study site. The sample plots were established navigating the coordinates in the field of 10 m ´ 10 m for pole and 1 m ´ 1 m for litter and grasses. Height and diameter at breast height were measured of pole, and samples of litter and grasses were collected. Meanwhile, the soil samples were collected from the centre of the plot from 0-0.1 m, 0.1-0.3 m and 0.3-0.6 m depths. The biomass was
calculated using standard equations and soil C, N, P and K contents were estimated in the lab. The result showed there were significant differences in carbon (C) stocks, it was 140.32 t/ha in treatment site 68.39 t/ha in control site of Shreepur public plantation while MAIC was found to be highest 10.19 t/ha in same site and lowest 3.39 t/ha in Bisbitty public plantation. Moreover, nitrogen was highest 98.41 kg/ha in 0- 0.1m and it was decreased according to soil depths in Shreepur public plantation and same trend was found in soil P and K. Hence, such type of intensive research is recommended in order to secure the candidacy for REDD+ reward.
