Abstract

Abstract Abstract Introduction and objective: Organic materials and their components are important elements in formation and stability of Soil aggregates and play a significant role in its construction. However; Distribution of organic materials in soil aggregates especially in Iran’s central dry areas aren’t that explicit. Suitable organic materials in soil tissues are important indicators of each ecosystem stability and in regard to the fact that organic materials are so scares in Iran, studying the soil quality of Gonabad farm lands seem to be essential. Hence; this study is about to determine the Carbon to Nitrogen ratio in Gondabad’s irrigated land area by qasabeh qanat in 2015. Methodology: the present study is descriptive. This study’s objective is to determine the Carbon to Nitrogen ratio in irrigated land’s soil by aqueduct borough according to present standards in technical journal number 893 of Soil and Water Research Institute (organic Carbon percentage with Wet oxidation method and Nitrogen with the Kjeldahl method of determining total Nitrogen). Sampling was done systematically. To obtain Carbon and Nitrogen amounts and their ratio all laboratory samples were experimented and for data analysis Excel and SPSS were run. Results: based on observations, we noticed that Carbon and Nitrogen percentage in Gonabad farm lands in comparison with standards was low, as in some areas Nitrogen amount is reported zero. Arid or semi-arid area is probably one of the cause for this problem. Hence; growing different plants in this area are relatively low, so, due to the slow pace of fresh plant material entrance into the soil, soil Carbon and nitrogen are low in this area. Conclusion: based on finding, in regard to the wet oxidation of organic carbon method in range of 0-15 and the Kjeldahl method of determining total Nitrogen, the Nitrogen percentage was so low and in some areas it has been reported zero. Also, according to obtained amounts for Carbon and Nitrogen, C/N ratio in range 0-57 was reported.
