KERAGAMAN CACING TANAH PADA LAHAN DENGAN BERBAGAI MASUKAN BAHAN ORGANIK DI DAERAH LAMPUNG UTARA

Abstract

A study has been done to know earthworms diversity on land with different resources of organic
matter in North Lampung area, Sumatera.The land were secondary forrest, alley cropping with organic
mater resources from gamal
(Gliricidia sepium
), soga
(Peltophorumdasyrrachis
) and mixture of G.
sepium and P. dasyrrachis andrest land
(without other organic matter resources except from harvest
residues of yellow corn
(Zea mays
).It have found seven species totaly in the research land. On the
secondary forrest was found seven species perfect. Changing it to alley cropping was consequence
one species lost
(Metapheretima carolinensis
) and changing it to general agriculture without other
organic matter resources except from plant harvest residues was consequence two spesies lost
(M.
carolinensis and Dichogaster crawi
). Different resources of organic matter on land were made
inquire factor of earthworms diversity that lived in the soil.
