Crystalline Structure Properties Of Bleached And Unbleached Wheat Straw (Triticum Aestivum L.) Soda-Oxygen Pulp, Esat Gümüşkaya, Mustafa Usta
Turkish Journal of Agriculture and Forestry
In this study, the crystallinity index and crystallite size of wheat straw powder, soda-oxygen pulp and soda oxygen pulp bleached with hypochlorite (H) and hypochlorite and peroxide (HP) sequences were determined using an x-ray diffractometer method. The crystallinity indexes of these pulp samples were found to be 45.61%, 52.00%, 52.60% and 54.11%, respectively. The crystallite sizes of these pulp samples were also determined and were 6.4 nm, 3.4 nm, 4.3 nm and 4.6 nm, respectively. On the other hand, the crystallinity index and crystallite size of holocellulose, cellulose and alpha-cellulose in wheat straw were then found to be 65.00%, 55.20% …

The Effect Of Wheat Straw, Corn Straw And Tobacco Residues On Denitrification Losses In A Field Planted With Wheat, Ali̇ Coşkan, Mustafa Gök, Işik Onaç, İlker İnal, Turan Sağlamti̇mur
Turkish Journal of Agriculture and Forestry
A field experiment was conducted to determine the effects of different organic residues (OR) (e.g., wheat straw corn straw and tobacco residues) on nitrogen mineralization and denitrification loss (N_2O-N) using application rates recommended to local farmers. Nitrate and ammonium analyses were carried out on periodically collected soil samples. In-situ denitrification loss was determined using the acetylene inhibition technique (AIT). The results revealed that OR application increased N mineralization significantly. In the favorable conditions for nitrification and intensive mineralization period, NO_3^--N accumulation at 0-60 cm depth peaked at 163.0, 177.7 and 226.6 kg N ha^{-1} in plots with wheat straw, corn …
