Past approach to control erosion and restoring forest function have been by forceful replacement of coffee plant
with timber or leguminous tree species such as Calliandra calothirsus, and eviction of the farmers from the forest
jurisdiction area. This research was aimed at testing the level of soil loss under different soil conservation treatments
on land covered by 3 year old coffee trees. The research was conducted on land with slopes ranging from 50 to 60%
at Laksana and Tepus sites of Sumberjaya District, West Lampung province from November 2001 to July 2003.
Erosion measurement was conducted at plots 15 m long and 8 m wide. Five treatments in 4 replications in a
completely randomized block design included: T1 = Sun coffee (open field monoculture coffee), T2 = T1 + Gliricidia
as shade tree, T3 = T2 + dead end trench (rorak), T4 = T2 + hedgerows of natural vegetation, and T5 = T2 + ridging.
The results indicated that erosion level on the 3 year old coffee farm with porous soil structure was very low (&lt; 2
Mg ha-1 yr-1) and thus soil conservation treatments had no significant effects on soil loss, run-off, and soil organic
matter and nutrient lateral transport. Soil physical properties (especially drainage pore and permeability) are dominant
factors that determine the level of soil loss in the study sites. The results of the research proved that, for areas
covered by 3 year old or older coffee, with soil structure similar to that of Laksana and Tepus, coffee trees per se are
sufficient to control erosion to tolerable level.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
