Abstract

A incubation experiment is carried out in a wood tent under aerobic and anaerobic with CRD design at 3 replicates in 24 experimental units. The experiment treatments include ( Cow residue , date palm residues without adjusted C/N , date palm residues with adjusted C/N to 1/19 and soil is used as control treatment , The organic components are characterize and measured of the content organic weekly during incubation period for 4 months. The results showed that The aerobic decomposition is faster than anaerobic decomposition , The organic residues of organic matter are reduced under anaerobic condition from 54.59 gm.Kg-1 after 7 days to reach a value of 48.68 gm.Kg-1 after 54 day of incubation period, while under aerobic conditions it is 52.33 gm.Kg-1 to reach a value of 43.81 gm.Kg-1 after 54 day of incubation period and show there are differences significant at 21 , 28 , 35 , 42 , 48 and 54 days respectively, Also The adjusted and non-adjusted date palm residues showed a significant difference superiority in the organic content. matter in all periods
