Effects of the lime nitrogen additive on maturing of artificial compost made frommatured oats (Avena sativa L.) soilage were investigated.Three groups of 50 kg(raw weight) soiling oats cut on after-ripening stage werepiled into experimental pots for compost maturing and three levels of limenitrogen were added in each group, at O (treatment I), 2.5 (II) and 5.0 kg (III)respectively. After piling of materials, the samples for the determination ofcarbon and nitrogen contents were obtained at two-week interval, during eightweeks. One part of the samples from each group were dried and measureddirectly the carbon and nitrogen concentrations, and the ather part of sampleswere analized after exclusion of water soluble compornents.
The results were sumarized as follows:
1. In any treatment, the carbon concentrations of compost, showed the values40~46% of dry matter, were not changed markedly during experimental period.
2. The nitrogen concentrations on treatment II and III were increased by 172 %and 136 % respectively, in eight weeks after piling, for the samples removedwater soluble compornents, compaired to the values of two weeks after piling.
3. The C:N ratio of composts, calculated from the carbon and nitrogen contentson exclusive samples of water soluble compornents, were 71.5, 17.6 and 27.4 fortreatment I, II and III respectively. It was considered that addition of 2.5 kg limenitrogen to 50 kg oats soilage (treatment II) could be obtained the most desirableresult.
