Abstract
Currently , many have been concerned with the oil palm cultivation since it may also put land resources in danger and bring about environmental damage. Poor practices in managing agricultural land very often occur due to the inadequate knowledge of soil conservation. Application of soil and water conservation is to maintain the productivity of the land and to prevent further damage by considering land capability classes. This research was aimed at obtaining soil and water conservation techniques which are the most appropriate and optimal for oil palm cultivation areas based on land capability classes which can support sustainable oil palm cultivation. Several soil conservation techniques had been treated to each different class III, IV, and VI of the studied area. These treatment had been performed by a standard plot erosion. The results showed for the land capability class III, Cover plants + Manure was able to control runoff, erosion and reduce leaching of N (LSD P≤0,05), in which soil conservation produced the lowest erosion (3,73t/ha), and N leaching (0,25%). On land capability class IV, Sediment Trap + cover plants+ manure was able to control runoff, erosion and reduce organic C and P leaching (LSD P≤0,05), in which soil conservation produced the lowest runoff (127,77 m 3 /ha), erosion (12,38t/ha), organic C leaching (1,14 %), and P leaching (1,28 ppm). On land capability class VI, there isn’t significant effect of soil conservation, but Bench Terrace + cover plants +manure has the lowest runoff, erosion and soil nutrient leaching.
Highlights
Oil palm trees have been widely grown in many parts of Indonesia
This research was aimed at obtaining soil and water conservation techniques which are the most appropriate and optimal for oil palm cultivation areas based on land capability classes which can support sustainable oil palm cultivation
The research was conducted in community oil palm plantations wich already pre-determined of their land capability classes (III, IV and VI)
Summary
In Aceh Province, in Bireuen Regency, these plants have shown rapid development in recent years. In 2012, for example, the land prepared for developing oil palm plantation reached 27.434 ha, spreading across seven subdistricts (IICB, 2014). The magnitude of the oil palm potential development in Bireuen Regency is undoubtedly crucial to the increase in foreign exchange earnings. The plantations are generally on the land slope of 15-60%, with land capability classes III - VII (Satriawan and Fuady, 2012). The land classes III and IV are still appropriate for agricultural activities when accompanied by the application of appropriate soil conservation technologies. Land capability classes of V - VII are very vulnerable to damage if used for agricultural activities (Saida et al, 2013)
