Abstract EN
A laboratory study was carried out to assess the impact of compost types and compost levels on soli respiration rate and enzymatic activity in different soil texture.
the experiment was a factorial on the basis of completely randomized design including three factors with three replication, the first factor involved five soils texture(s1debaga,s2 bakrajaw,s3 zawita,s4 kanyshireen,s5 agholan), second factor involved four compost types(c1 indian,c2 dutch,c3 estonia,c4 coca cola company), third factors included three levels (0, 1 and 2 ton.donum-1) and their combinations.
the soil respiration rate was measured by using an alkali absorption technique, in this study a container of ( 8 cm diameter and 14.4 cm in high ) was used as co2 isolation chamber for thus (a 180) isolation chamber prepared and divided by the soils texture, the experimental treatments was designed in factorial completely randomized design with three replication.
the results indicate that highest values were (133.501, 21.586, and 3.409 of dehydrogenase μgtpf.g-1, urease μgn.g-1 soil and soil respiration rate g.co2.m-3.day-1 were recorded in (s4) sandy clay loam.
the highest values were (111.904), (21.055) and (2.597) of (dehydrogenase, urease) and (soil respiration rate) were recorded from (c1) and (c4) treatment respectively.
the application of 1ton.donum-1 led to increase dehydrogenase, urease activity and soil respiration rate respectively.
