Abstract
Cellulosic wastes constitute the majority of agricultural fields. The purpose of this study was to utilize these cellulosic wastes such as wheat straw and wheat straw cellulose on soil carbon mineralization in a sandy loam soils. Two different doses (100 and 1000 mg) of wheat straw cellulose were used to determine the carbon mineralization using CO2 respiration method. The cumulative carbon mineralization was found to be highest at the minumum doses of wheat straw cellulose with nitrogen (W-CL-N, 19.65 mg) and the lowest at the maximum doses of wheat straw (W-Straw, 14.32 mg). The results showed that the application of wheat straw cellulose at minumum doses resulted in higher carbon mineralization rate. The maximum carbon mineralization rate was observed in soil with minimum wheat straw cellulose and nitrogen source were added (1.41%). Whereas, the minimum carbon mineralization rate was determined in the soil mixed maximum wheat straw (1.03 %). The soil mixed maximum wheat straw was determined the lowest carbon mineralization rate due to its complex structure. The use of nitrogen source and organic matter with cellulose have positive effect on soil carbon mineralization. It might be said that these results describe an effective way for disposal of organic wastes.
