| Abstrak/Abstract |
One of the important factors in agricultural practices is the soil water availability for crops.
This study was aimed to identify landslide deposits, to assess the soil characteristics of each landslide
zone, the effect of soil physical characteristics on the soil water availability for crops, and to
determine the availability of water for crops in landslide deposits. The soil sampling was carried out
by purposive sampling method at 12 landslide points and 4 zones, i.e. crown, main-scarp, main-body,
and toe-slope at 2 soil depths (0-100 cm and 100-200 cm). The data were analyzed with a regression
test and standard deviation method. The results showed that the high soil water availability for crops
occurred at the toe-slope zone, 0-100cm depth and at the main-scarp zone, 100-200 cm depth. The
soil physical properties clearly correlated with soil moisture content. Based on the soil water
availability level, it might be suitable for seasonal crops (i.e cassava) at the toe-slope zone and annual
crops (i.e Albizia chinensis) at the main-scarp zone. Therefore, landslides in the Bompon Sub-
watershed, Magelang is potentially utilized for agricultural development. Estate crops suitable in the
study area are sweet potatoes, cassava, and ginger. |
