| dc.description.abstract | The results showed that on upland rice fields with sediment found five genus of
fungus with number of colonies 4.0 x 103
cfu/g to 9.3 x 104
cfu/g; three bacterial families with
number of colonies 7,1 x 104 cfu/g to 2,8 x 105
cfu/g; and five genera of nematodes with the
amount of 2.6 x 102 /kg of soil to 1.1 x103
/kg of soil.In unpolished upland rice fields were
found four genus of fungus with colonies of 2.4 x 103
cfu/g to 8.4 x 104
cfu/g, three bacterial
families with number of colonies 1.2 x 105
cfu/g to 2.7 x 105
cfu/g and four genera of
nematodes with the amount of 9.6 x 102
/kg of soil to 1.1 x103
/kg of soil. The most common
microbes are Aspergillus, Cladosporium, Penicillium, Phytium and Trichoderma (fungi),
Achromobacteraceae, Brevibacteriaceae, Micrococcaceae (Bacteria), as well as Dorylaimus,
Hemicycliophora, Mononchus, Meloidogyne, Paratrichodorus, Radopholus, Rotylenchulus,
Rhabditis, Seinura and Trichodorus (Nematodes). Fungi, bacteria and nematodes have a good
role in the process of soil decomposition. The results of soil chemical analysis showed that soil
fertility is lower in upland rice fields with sediments compare to those without sediment.
