Abstract

ABSTRAKA study has been done to know relation of earthworm with physic, chemist and microbiologiccondition of ultisol acid soil in North Lampung, Sumatera. The research indicated there was strongpositive correlation between contents of light and moderate fractions of soil organic matter and Corganikwith earthworm population. There was strong positive correlation between contents of totalfraction, light and moderate fractions of soil organic matter, C-organic and earthworm population withtheir freshweight. There was strong positive correlation between contents of total fraction, moderateand heavy fractions of soil organic matter, N-total and earthworm freshweight with sum of theircocoons. There was strong positive correlation between contents of light and moderate fractions ofsoil organic matter, C-organic, N-total and earthworm freshweight with weigth of their casts. Thepopulation, freshweight, sum of cocoons and casts weight of eartworms have positive correlation withsoil porosity. Soil temperature have negative correlation on all of variables. Sum of fungi and totalmicroorganisms have not strong correlation on the earthworms. The low of soil pH have not negativeeffect on the earthworms, it was suspected because which was lived in there were all of adaptablespecies with ultisol acid soil.Keywords : Earthworm, Physic, Chemist dan Miocrobiologic Condition, Ultisol Acid Soil

Abstract

ABSTRAKA study has been done to know earthworms diversity on land with different resources of organicmatter in North Lampung area, Sumatera.The land were secondary forrest, alley cropping with organicmater resources from gamal (Gliricidia sepium), soga (Peltophorumdasyrrachis) and mixture of G.sepium and P. dasyrrachis andrest land (without other organic matter resources except from harvestresidues of yellow corn (Zea mays).It have found seven species totaly in the research land. On thesecondary forrest was found seven species perfect. Changing it to alley cropping was consequenceone species lost (Metapheretima carolinensis) and changing it to general agriculture without otherorganic 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 madeinquire factor of earthworms diversity that lived in the soil.Keywords : Diversity, Earthworms, Soil Organic Matter
