Abstract
Relationship between Distance Sampling and Carbon Dioxide Emission under Oil Palm Plantation
Highlights
Forest is the most stable ecosystem in the earth
Returning of organic matter through leaves fall and branches decomposition supply forest soil with adequate nutrient which make the nutrient cycling within the forest ecosystem almost balance (Jordan 1985; Wilcke et al 2001)
The main purpose of this research was to examine for the effect of various ages of rubber plantation in the changes of soil properties in Dhamasraya district, West Sumatra Indonesia
Summary
Forest is the most stable ecosystem in the earth. Hydrology and nutrient cycle in forest can protect the forest ecosystem from drought and nutrient insufficiency. Returning of organic matter through leaves fall and branches decomposition supply forest soil with adequate nutrient which make the nutrient cycling within the forest ecosystem almost balance (Jordan 1985; Wilcke et al 2001). This condition put forest ecosystem as parameter and control for the soil fertility changing in other ecosystem (Donald 2003). Dhamasraya district is the one of rubber plantation center in West Sumatra which contributes more than 50% of total crumb rubber production from this province. Deforestation and land use change from other agricultural purposes to rubber plantation are common problem in this area, which potent to create some ecological problems such as decreasing in biodiversity, hydrological cycle disturbance, and increasing rate of organic matter decomposition, accelerate erosion process, degradation on physical and chemical of soil properties (Yasin 2004; Irwan et al 2008)
