Carbon Dioxide Emissions of Belangeran(Shoreabalangeran) Plant Growing in the Rehabilitation Program in Peatland Area, Indonesia
At present the failure of peatland rehabilitation is not only due to the quality of the seedlings that have not met the standard quality, but also the physical condition of the land, especially in Central Kalimantan. The land to be rehabilitated generally has a low pH, a thin topsoil layer and is poor in nutrients, especially phosphorus (P). These three things generally cause failure, so that many crops in the field experience stress which results in the death of seedlings after planting. Taking this fact as departing point, it is necessary to have a reference that has been tested and evaluated in various peatland rehabilitation activities so that it can become a basis for consideration in preparing a peatland rehabilitation plan in PulangPisau Regency. This study examine the growth rate of rehabilitation plants, namely BelPangeran plants at various plant ages (2 years and 4 years), calculate the CO2 emissions produced in the planting area during the rainy and dry seasons. Our results show, first, the growth of belangeran plants in revegetation areas had different characteristics, the highest plant height growth and the largest diameter were obtained at 2 year old plant locations (P2), namely 377.24 cm and 6.11 cm, followed by 4 year old plant locations (P3). Second, the largest CO2 emission is obtained in the open area (P1), followed by the 2 year old Belangeran plant (P2) and the 4 year old Belangeran plant (P3) during the rainy season, this is due to root and root respiration activities. soil, and the influence of groundwater level fluctuations (water table) that occurs in this region. Where the highest CO2 emissions occur in the rainy season, and the lowest in the dry season
