The research aims to understand the potential of marginal lands in joints as a land for agricultural production. Land potential can be observed by the soil’s nutrient binding ability. The joints in the research area had been observed to have caused steep slopes and shallow soils. However, plant growth is observed to be lush and fertile in the research area. The presence of plants is an indicator that the research area is capable of growing and producing plants as food resources.
The research was conducted with a field survey and laboratorium analysis approach. The field survey approach was first made with preparations through digital elevation method (DEM) maps and satellite imagery. DEM and satellite imagery can observe fault kekar in Giripurno Village. One of these fault joints has been observed in Pokoh, the sub-village in Giripurno Village. Field observation is conducted in slope erosional zones with heavy erosion processes. Field observation was conducted to know the morphology and vegetative condition of the area. Soil parent materials (rocks) and soil samples were gathered during field observation. After the field survey, laboratory analysis includes mineralogy, soil physics, and soil chemistry analysis. The research aims to observe the soil development and quality from the parent material to the soil as a medium for plant growth.
This research shows that marginal lands in joints have a high potential as a land for agricultural production. The soil minerals are adequate to become natural essential nutrients for the plants. The soil also has a loam texture, an optimum pH, and soil organic matter quantity for maintaining plant growth. This research concluded that land management includes mechanical and vegetative conservation to reduce land degradation and achieve food security.
