Abstract
The results obtained yielded useful and clear composting of to~vn refuse with compared with farmyard manure under aerobic condition, and t and microbiologi~al changes i yield. In addition,
concerning the with we.ter as the same treatments r effect on chemical il as well as on wheat
t organic waste materials
(town refuse + water ,town + sewage, farmyard manure
+ water or farmyard manure + were tested for the
production of biogas under condition.
The physical, microbiol chemical changes
occUlt’ring in the different tr town refuse +
water, town refuse + sewage, yard manure + water or
farmyard manure + sewage) du a composting period of
four month,s were studi ed. different organic waste
materi8ls were put in heaps ( m2/ton). In general, &11 numbers of :licro-organisms c :d,buting to soil ferti-

In 8 pot experiment; each ost WeS applied to soil
